ETA4257 1.2A/40V Fully Integrated Linear Charger

ETA4257 Description

ETA4257 1.2A/40V Fully Integrated Linear Charger for 1 Cell Li-ion Battery .
ETA4257 is a single cell, fully integrated constant current (CC)/constant voltage (CV) Li-ion battery charger.

ETA4257 Features

* 40V input standoff voltage
* 4.2V charge termination voltage
* 2.6V trickle charge threshold
* Charge current programmable, up to 1.2A
* 400nA BAT current when no charging
* Soft-start limits in-rush current
* Fault and Charge Status Indicator
* DFN3x3-10 APPLICATIO

ETA4257 Applications

* No external sense resistor or blocking diode is necessary for the ETA4257. Build-in thermal feedback mechanism regulates the charge current to control the die temperature during high power operation or at elevated ambient temperature. The ETA4257 has a pre-charge function for trickle charging deepl
