Microchip Technology, Inc. PMIC - Battery Chargers MCP73842T-820I/UN

The MCP73842T-820I/UN is a dual-cell lithium-ion/lithium-polymer charge management controller designed for applications requiring an 8.2V preset voltage regulation. It operates within an input voltage range of 8.7V to 12V and features high-accuracy voltage regulation with a maximum deviation of ¬±0.5%. The device supports programmable charge current and safety timers, ensuring effective management of battery charging processes. It includes preconditioning for deeply depleted cells, automatic end-of-charge control, and optional continuous cell temperature monitoring. The MCP73842T-820I/UN is packaged in a compact 10-pin MSOP format and is specified for operation over a temperature range of -40¬8C to +85¬8C, making it suitable for space-constrained and cost-sensitive applications such as cradle chargers, digital cameras, and hand-held instruments.
