ETA40543 Description
ETA40543 1.2A/16V Fully Integrated Linear Charger for 1 Cell 4.35V Li-ion Battery .
ETA40543 is a single cell, fully integrated constant current (CC)/constant voltage (CV) Li-ion battery charger.
ETA40543 Features
* 16V input standoff voltage
* 4.35V charge termination voltage
* 2.9V trickle charge threshold
* Charge current programmable, up to 1.2A
* 250nA BAT current when no charging
* Soft-start limits in-rush current
ETA40543 Applications
* No external sense resistor or blocking diode is necessary for the ETA40543. Build-in thermal feedback mechanism regulates the charge current to control the die temperature during high power operation or at elevated ambient temperature. The ETA40543 has a pre-charge function for trickle charging dee
