LP3945 Battery Charge Management

LP3945 Description

LP3945/LP3946 Battery Charge Management System October 2003 LP3945/LP3946 Battery Charge Management System General .
The LP3945 and LP3946 are complete charge management systems that safely charge and maintain a Li-Ion battery or a four-cell Ni-MH (LP3945 only) batte.

LP3945 Features

* Ni-MH charging mode as well. The charger has under-voltage and over-voltage protection as well as an internal 5.6 hr timer to prevent overcharging the battery. There are two open drain outputs for status indication. An internal amplifier readily converts the charge current into a voltage. Also, the
