Description:

1.2A/16V Fully Integrated Linear Charger

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

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
