GENERAL DESCRIPTION
The XC6801 series is a constant-current/constant-voltage linear charger IC for single cell lithium-ion batteries. The XC6801 includes a reference voltage source, battery voltage monitor, driver transistor, constant-current/constant-voltage charge circuit, overheat protection circuit and phase compensation circuit. The battery charge termination voltage is internally set to 4.2V ±0.7% and the trickle charge voltage and accuracy is 2.9V ±3%. In trickle charge mode, a safe battery charge is possible because approximately only 1/10 of the full charge current is supplied to the battery. As it is possible to select a highly accurate charge current of either 100mA (MAX.) for L level input to the LIM pin or 500mA (MAX.) for H level, the series is ideal for applications where the charge is from USB. The series’ charge status output pin, /CHG pin, is capable of checking the IC’s charging state via connection to an external LED.

Description
The Elan EM198810 IC is a low-cost, fully integrated CMOS radio frequency (RF) transceiver block, combined with a 64-byte buffered framer block. The RF transceiver block is a self-contained, fast-hopping GFSK data modem, optimised for use in the widely available 2.4 GHz ISM band. It contains transmit, receive, VCO and PLL functions, including an on-chip channel filter and resonator, thus minimizing the need for external components. The receiver utilizes extensive digital processing for excellent overall performance, even in the presence of interference and transmitter impairments. Transmit power is digitally controlled. The low-IF receiver architecture results in sensitivity to -80dBm or better, with impressive selectivity.
In normal applications, the EM198810 is connected to a low cost microcontroller(ex:EM78P451S).
In normal application The on-chip framer processes and stores the RF data in the background, unloading this critical timing function from the MCU. This lowers MCU speed requirements, expedites product development time, and frees the MCU for implementing additional product features.
The framer register settings determine the over-the-air formatting characteristics. Many configurations are possible, depending on the user’s specific needs. Raw transmit data is easily sent over-the-air as a complete frame of data, with preamble, address, payload, and CRC. Receiving data is just the opposite, using the preamble to train the receiver clock recovery, then the address is checked, then the data is reverse formatted for receive, followed by CRC. All of this is done in hardware to ease the programming and overhead requirements of the baseband MCU.
For longer battery life, power consumption is minimized by automatic enabling of the various transmit, receive, PLL, and PA sections, depending on the instantaneous state of the chip. A sleep mode is also provided for ultra low current consumption.
This product is available in 32-lead 5x5 mm JEDEC standard QFN package, featuring an exposed pad on the bottom for best RF characteristics. Lead-free RoHS compliant packaging is available on request.

FEATURES
The EM198810 is a CMOS integrated circuit that performs all functions from the antenna to the microcontroller for transmission and reception of a 2.4GHz digital data. This transceiver IC integrates most of the functions required for data transmission into a single integrated circuit. Additionally, the programmability implemented reduces significantly external components count, board space requirements and external adjustments.
Key Features
*Combines 2.4 GHz GFSK RF transceiver with 8-bit data framer function
*Eliminates need for external software or hardware FIFO; offloads MCU for other tasks

Description
The ATS617 gear-tooth sensor IC is a peak-detecting device that uses automatic gain control and an integrated capacitor to provide extremely accurate gear edge detection down to low operating speeds. Each device consists of a high-temperature plastic shell that holds together a samarium-cobalt pellet, a pole piece, and a differential open-collector Hall IC that has been optimized to the magnetic circuit. This small package can be easily assembled and used in conjunction with a wide variety of gear shapes and sizes.
The technology used for this device is Hall-effect based. The device incorporates a dual-element Hall IC that switches in response to differential magnetic signals created by ferromagnetic targets. The sophisticated processing circuitry contains an A-to-D converter that self-calibrates (normalizes) the internal gain of the device to minimize the effect of air gap variations. The patented peak-detecting filter circuit provides immunity to magnet and system offsets and has the ability to discriminate relatively fast changes such as those caused by tilt, gear wobble, and eccentricities. This easy-tointegrate solution provides first falling edge detection and stable operation to extremely low rpm. The ATS617 can be used as a replacement for the ATS616.
The ATS617 is ideal for use in systems that gather speed, position, and timing information using gear-tooth-based configurations. This device is particularly suited to those applications that require extremely accurate duty cycle control or accurate edge-detection, such as automotive camshaft sensing.
The ATS617 is provided in a 4-pin SIP that is Pb (lead) free, with a 100% matte tin plated leadframe.

Features and Benefits
*Self-calibrating for tight timing accuracy
*First-tooth detection
*Immunity to air gap variation and system offsets
*Immunity to signature tooth offsets

DESCRIPTION
The QT60320 digital charge-transfer (“QT”) QMatrix™ IC is designed to detect touch on up to 32 keys in a scanned X-Y matrix. It will project the keys through almost any dielectric, like glass, plastic, stone, ceramic, and even most kinds of wood, up to thicknesses of 5 cm or more. The touch areas are defined as simple 2-part interdigitated electrodes of conductive material, like copper, Indium-Tin-Oxide (ITO), or screened silver or carbon deposited on the rear of the control panel. Key sizes, shapes and placement are almost entirely arbitrary; sizes and shapes of keys can be mixed within a single panel of keys and can vary by a factor of 20:1 or more in area. The gain (sensitivity) and threshold of each key can be set individually via simple commands over the UART port, for example via the freeware QmBtn program. Key setups are stored internally in an onboard eeprom and do not need to be reloaded.
The IC is designed specifically to work with appliances, ATM machines, security panels, portable instruments, machine tools, or similar products that are subject to environmental 'challenges' or even physical attack. It permits the construction of 100% sealed, watertight keypanels that are immune to environmental factors such as humidity and condensation, temperature, dirt accumulation, or the physical deterioration of the panel surface from abrasion, chemicals, or abuse. To this end the QT60320 contains Quantum-pioneered self-calibration, drift compensation, and digital filtering algorithms that make the sensing function extremely robust and survivable.
The device can readily control keys over graphical LCD panels or LEDs when used with clear, conductive ITO electrodes. It does not require 'chip on glass' or other exotic fabrication techniques, thus allowing the OEM to source the keymatrix from multiple vendors.
External circuitry consists of an opamp, a common PLD, and a quad fet switch, which can fit into a footprint of roughly 1 square inch (6.5 sq. cm). The device also can control two status LEDs, and includes in addition 8 addressable output drive lines and 4 readable spare input lines which can be used to control LEDs, LCDs, or other panel functions without requiring additional control lines from the host CPU. It also makes available to the user 86 bytes of onboard writeable and readable eeprom via the serial interface, thus helping to reduce system cost by eliminating extra components.
QT60320 technology makes use of an important new variant of charge-transfer sensing, transverse charge-transfer, in an XY format that minimizes the number of required scan lines. Unlike older technologies it does not require one IC per key, and is cost competitive even with some membrane technologies. In many cases it can also replace resistive XY sense elements commonly used in touch screens, at a fraction of the price.
This part is not recommended for new designs. Consult Quantum for advice on alternatives.

FEATURES
*Creates 32 ‘touch buttons’ through any dielectric
*100% autocal for life - no adjustments required
*'N' key rollover: senses all 32 keys in parallel
*Keys individually adjustable for sensitivity
*Mix 'n match key sizes & shapes in one panel
*Tolerates a 20:1 variance in key sizes on a panel
*Panel thicknesses to 5 cm or more
*Back lit keys possible with ITO electrodes
