Introduction

AI Translation

FM5001L is a power management IC integrating lithium battery charge management, lithium battery protection, DC-DC boost current-limiting, and 3-speed adjustable fan drive functions; designed specifically for portable fans powered by lithium batteries.

FM5001L supports a complete charging sequence including trickle charging, constant current charging, and constant voltage charging, with charge indicator and full-charge indicator LEDs; supports fan drive function with built-in 3-speed adjustable airflow control and discharge LED indication; when battery voltage drops below 2.9V, FM5001L enters under-voltage state with a total system current of 30uA; built-in constant current charging at 600mA.

FM5001L features multiple protection designs, including load overcurrent protection, anti-backflow protection during charging, short-circuit latch-up prevention, soft-start protection, lithium battery over-discharge protection, over-temperature protection, and under-voltage protection.
