LT LTC4009IUF-1#PBF

Overview

The LTC4009IUF is a constant-current/constant-voltage battery charger controller. It uses a synchronous quasiconstant frequency PWM control architecture that will not generate audible noise with ceramic bulk capacitors. Charge current is set by the combination of external sense, input and programming resistors. With no built-in termination, the LTC4009IUF family charges a wide range of batteries under external control.

The CHRG status pin is active during all charging modes, including special indication for low charge current.
