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 APE8955 is a 5A ultra low dropout linear regulator. The product is specifically designed to provide well supply voltage for front side bus termination on motherboard and NB applications. The IC needs two supply voltages, a voltage for the circuitry and a main supply voltage for power conversion, to reduce power dissipation and provide extremely low dropout. The APE8955 integrates many functions. A Power-on-Reset(POR) circuit monitors both supply voltage to prevent wrong operations. A thermal shutdown and current limit functions protect the device against thermal and current over-load. A POK indicates the output status with time delay which is set internally. It can control other converter for power sequence. The APE8955
can be enabled by other power system. Pulling and holding the EN pin below 0.4V shuts off the output. The APE8955 is available in ESOP-8 package which features small size as SO-8 and exposed pad to reduce the junction-to-case resistance, being applicable in 2~3W applications.

General Description
The LP38855 is a high-current, fast-response regulator which can maintain output voltage regulation with an extremely low input to output voltage drop. Fabricated on a CMOS process,
the device operates from two input voltages: VBIAS provides power for the internal bias and control circuits, as well as drive for the gate of the N-MOS power transistor, while VIN supplies
power to the load. The use of an external bias rail allows the part to operate from ultra low VIN voltages. Unlike bipolar regulators, the CMOS architecture consumes extremely low quiescent
current at any output load current. The use of an NMOS power transistor results in wide bandwidth, yet minimum external capacitance is required to maintain loop stability.
The fast transient response of this device makes it suitable for use in powering DSP, Microcontroller Core voltages and Switch Mode Power Supply post regulators. The LP38855 is
available in TO-220 and TO-263 5-Lead packages.
Dropout Voltage: 130 mV (typical) at 1.5A load current.
Low Ground Pin Current: 14 mA (typical) at 1.5A load current.

General Description
The MLX90255xx linear sensor array consists of a 128 x 1 array of photodiodes, associated
charge amplifier circuitry and a pixel data-hold function that provides simultaneous integration
start and stop times for all pixels. The pixels measure 200μm (H) by 66 μm (W) and there is 8
μm spacing between pixels. Operation is simplified by internal control logic that requires
only a Serial Input (SI) pulse and a clock signal. The sensor consists of 128 photodiodes
arranged in a linear array. Light energy falling on a photodiode generates photocurrent, which is integrated by the active integration circuitry associated with that pixel. During the integration
period, a sampling capacitor connects to the output of the integrator through an analog
switch. The amount of charge accumulated at each pixel is directly proportional to the light
intensity and the integration time. The output and reset of the integrators is controlled by a
132-bit shift register and reset logic. An output cycle is initiated by clocking in a logic 1 on SI.
This causes all 132 sampling capacitors to be disconnected from their respective integrators
and starts an integrator-reset period.
