HM8202 - Standalone Li-Ion Switch Mode Battery Charger

General Description

The HM8202 is a complete battery charger controller for two (8.4V) cells lithium-ion batteries.

The HM8202 provides a small, simple and efficient solution to fast charge Li-ion battery.

An external sense resistor sets the charge current with high accuracy.

Key Features

  • Input Supply Range: 9V ～ 14V.
  • End-Charge-Current Detection Output.
  • Constant Switching Frequency for Minimum Noise.
  • Automatic Battery Recharge.
  • Automatic Shutdown When Input Supply is Removed.
  • Automatic Trickle Charging of Low Voltage Batteries.
  • Battery Temperature Sensing.
  • Stable with Ceramic Output Capacitor.
  • SOP-8L Package.
