A4062 - STANDALONE Li-ION SWITCH MODE BATTERY CHARGER

Datasheet Summary

Features

  • The A4062 is a complete battery charger controller for two (8.4V) cell lithium-ion batteries. With a 500kHz switching frequency, the A4062 provides a small, simple and efficient solution to fast charge Li-Ion batteries from a wide range of supply voltages. An external sense resistor sets the charge current. An internal resistor divider and precision reference set the final float voltage with ±1% accuracy. When the input supply is removed, the A4062 automatically enters a low current sleep mode,.

With a 500kHz switching frequency, the A4062 provides a small, simple and efficient solution to fast charge Li-Ion batteries from a wide range of supply voltages. An external sense resistor sets the charge current. An internal resistor divider and precision reference set the final float voltage with ±1% accuracy. When the input supply is removed, the A4062 automatically enters a low current sleep mode, dropping the battery drain current to 20μA.
