EUP8092 - 1.5A Linear Li-Ion/Polymer Charger IC

Description

The EUP8092 series are highly integrated single cell Li-Ion/Polymer battery charger IC designed for handheld devices.

This charger is designed to work with various types of AC adapters or a USB port and capable of operating with an input voltage as low as 2.65V.

Features

thermal regulation loop to control charge current to keep safe operation when PCB lacked of enough heat-sinking. A programmable charge timer provides a backup safety for termination. The EUP8092 automatically re-starts the charge if the battery voltage falls below an internal threshold and automatically enters sleep mode when DC supplies are removed. No external sense resistor or blocking diode is required for charging. A yb NTC thermistor interface is used for charging the battery R ‘ in a safe.

EUP8092 1.5A Linear Li-Ion/Polymer Charger IC with Integrated FET and Charger Timer DESCRIPTION The EUP8092 series are highly integrated single cell Li-Ion/Polymer battery charger IC designed for handheld devices. This charger is designed to work with various types of AC adapters or a USB port and capable of operating with an input voltage as low as 2.65V. The EUP8092 operates as a linear charger and charges the battery in three phases: trickle current, constant current, and constant voltage. When AC-adapter is applied, an external resistor sets the magnitude of the charge current, which may be programmed up to 1.5A with TDFN10 package and a current-limited adapter for lowest power dissipation.
