NE57611 - Single cell Li-ion battery charger

General Description

The NE57611 is a one-cell, Li-ion battery charger controller which includes constant-current and constant voltage charging, a precise charge termination, and precharging of undervoltage cells.

It contains the minimum circuitry needed to safely charge a lithium-ion or lithium-polymer cell.

Key Features

  • 30 mV per cell charging accuracy from 0 °C to +50 °C.
  • Low quiescent current (250 µA.
  • ON; 2 µA.
  • OFF).
  • Undervoltage precharge detector.
  • Self-discharge maintenance charging.
