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 the host processor. A programmable charge timer provides the ability to detect defective batteries, and provides a seco.
