Battery Charger

15 parts

Linear and switching charge-management ICs for single-cell Li-ion / LiPo (and a few LiFePO4) batteries. They handle CC/CV charging, termination, and battery protection handshakes so you can charge safely from USB or a DC input.

How to choose

TP4056 / TP4054 — the budget default for ≤1 A linear charging from 5 V; huge community track record.
MCP73831 — tiny, well-documented linear charger for wearables and small boards.
BQ2407x / BQ24295 — pick these when you need power-path management (run the system while charging) or I2C control.
Linear chargers are simple but dissipate heat at high current — above ~1 A or with higher input voltages, prefer a switching charger.
