LTC4009-1 Datasheet Multi-chemistry Battery Charger

Manufacturer: Linear Technology (now Analog Devices)

This datasheet includes multiple variants, all published together in a single manufacturer document.

General Description

The LTC®4009 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 bination of external sense, input and programming resistors.
