Introduction

AI Translation

HE4056E is a complete single-cell lithium-ion battery constant-current/constant-voltage linear charge management IC. Thanks to its internal P-MOSFET architecture, no external sense resistor is required in the application. The maximum charge current is up to 1.1A; during high-power operation and elevated ambient temperatures, thermal feedback automatically reduces the charge current to lower the die temperature. The HE4056E includes two open-drain charge status pins: charge status indicator /CHRG and battery fault status output /STDBY.
