ISL9220A - Switching Charger

Download the ISL9220A datasheet PDF. This datasheet also covers the ISL9220 variant, as both devices belong to the same switching charger family and are provided as variant models within a single manufacturer datasheet.

Key Features

  • synchronous PWM technology, maximizing power efficiency, thus minimizing charge time and heat. The 1.2MHz switching frequency allows use of small external inductors and capacitors. A simple charge current programming method is provided. External resistors program the fast charge and end-of-charge currents. The two status outputs can be used to drive LEDs, or can be connected to host processor. A programmable charge timer provides the ability to detect defective batteries, and provides a secondar.
