Description
The MCP73837 and MCP73838 devices are fully integrated linear Li-Ion / Li-Polymer battery chargers with autonomous power source selection. Along with its small physical size, the low number of external components required makes the MCP73837/8 ideally suitable for portable applications.
The MCP73837/8 automatically selects the USB-Port or AC-Adapter as the power source for the system. For the USB-Port powered systems, the MCP73837/8 specifically adheres to the current limits governed by the USB specification. The host microcontroller can select from two preset maximum charge current rates of 100 mA (low power USB-port) or 500 mA (high power USB-port). With an AC-Adapter providing power to the system, an external resistor sets the magnitude of the system or charge current up to a maximum of 1A.
The MCP73837/8 employs a constant current / constant voltage charge algorithm with selectable preconditioning and charge termination. The constant voltage regulation is fixed with four available options: 4.20V, 4.35V, 4.40V, or 4.50V, to accommodated the new emerging battery charging requirements. The MCP73837/8 limits the charge current based on die temperature during high power or high ambient conditions. This thermal regulation optimizes the charge cycle time while maintaining the device reliability.
The MCP73837/8 are fully specified over the ambient temperature range of -40°C to +85°C.
The MCP73837/8 devices are available in a 10-Lead, 3 mm x 3 mm, DFN package or in a 10-Lead MSOP package.

The output current range is programmable to 4mA to 20 mA, 0mA to 20mA or an overrange function of 0mA to 24mA.
Voltage output is provided from a separate pin that can be configured to provide 0V to 5V, 0V to 10V, ±5V or ±10V output ranges, an over-range of 10% is available on all ranges.
Analog outputs are short and open circuit protected and can drive capacitive loads of 1uF and inductive loads of 1H.
The device is specified to operate with a power supply range from 10.8 V to 40 V. Output loop compliance is 0 V to AVDD – 2.5 V.
The flexible serial interface is SPI and MICROWIRE compatible and can be operated in 3-wire mode to minimize the digital isolation required in isolated applications.
The device also includes a power-on-reset function ensuring that the device powers up in a known state and an asynchronous CLEAR pin which sets the outputs to zero-scale / mid-scale voltage output or the low end of the selected current range.
The total output error is typically ±0.1% in current mode and ±0.05% in voltage mode.

DESCRIPTION
The BUF01900 and BUF01901 provide a programmable voltage output with 10-bit resolution. Programming of the output occurs through an industry-standard, two-wire serial interface. Once the correct VCOM voltage is established it can easily be stored into the integrated nonvolatile memory.
An initial output voltage and adjustment range can be set by an external resistor-divider. With its large output current capability (up to 100mA), the BUF01900 and BUF01901 are ideally suited as programmable VCOM calibrators in LCD panels.
The BUF01901 has the digital-to-analog converter (DAC) output brought out directly. It has a slightly lower cost than the BUF01900, and works very well with the integrated VCOM in traditional gamma buffers such as the BUFxx702, BUFxx703, BUFxx704 and BUF11705.
The BUF01900 and BUF01901 are both available in TSSOP-8 and 3mm x 3mm DFN-10 packages. The DFN-10 package (only 0.9mm in height) is especially well-suited for notebook computers. Both devices are specified from −40°C to +85°C.
