MCHPMCP73871T-1CCI/ML
Overview
The MCP73871T-1CCI/ML is a highly integrated lithium-ion/polymer battery charge management controller with system load sharing and power-path management. It allows for simultaneous battery charging and system powering from a single input source, such as a USB port or an AC-DC wall adapter, ensuring the system remains powered even when the battery is deeply depleted.
Why Choose This Part
This controller features Voltage Proportional Current Control (VPCC) which ensures the system load is prioritized while preventing input power source overload. It includes an integrated ideal diode for low-loss power-path management and provides a complete linear charge solution with programmable fast charge and termination set points in a compact 20-lead QFN package.
Applications
Key Specifications
Getting Started
Engineers can evaluate this part using the MCP73871 Evaluation Board (MCP73871EV) to test different charging configurations and load sharing scenarios. Design requires only a few external resistors to program the charge current up to 1.1A and the termination threshold, along with standard decoupling capacitors as specified in the datasheet.
