It integrates over-current, over-temperature, over-voltage, and reverse-current fault protection, reducing external monitoring components on the board.
Charge current and input voltage headroom
Maximum charge current is 7A — this is the continuous constant-current ceiling for a single cell. The maximum supply voltage is 6V, so the input rail must stay below that; a 5V USB or adapter supply is typical, with headroom for cable drop. The I²C interface lets the host adjust the charge current, termination voltage, and timer settings dynamically.
Fault protection set reduces external bill
On-chip fault protection covers over-current, over-temperature, over-voltage, and reverse-current conditions.
