General Description

The SGM41524 is a compact and efficient Lithium ion (Li+) or Lithium ion polymer (Li+/polymer) battery charger.

It can provide power and charge the single cell battery of a system typically found in compact portable device.

An internal switching buck converter regulates the supply input for charging the battery and powering the system even if the battery is absent.

Key Features

resistor programmable constant current and constant voltage charging capability plus a charge limiting timer and operates in compliance with the BAJ/JEITA safety guide. An NTC (β = 3950K) can be used for battery temperature sensing on top of the internal junction temperature monitoring. The IND status output pin can be connected to LEDs to indicate the operating conditions, such as power input ok (POK), in charging (CHG), VIN over-voltage (POK and CHG alternate blinking) and no power/disabled (O.
