Lithum-ion charging and protection circuit
« on: October 21, 2017, 03:00:28 pm »
Hi,

I'm making my first lithium-ion charging/protection circuit and I'm hoping for a few extra pairs of eyeballs to spot any mistakes I may have made..

The charging controller is an MCP73812 and the protection IC is an AP9101CAK-ABTRG1. Q1 and Q2 are IRLML6344TRPBF logic level N-channel mosfets. It's for a single 18650 cell. Maximum discharge current ~500mA.

Attached schematic.
