PIN PIN # NAME 1 2 3 4 5 6 7 8 9 10, 11 12 13, 14 15, 16 17 18 19 DESCRIPTION STAT2 Open-drain indication pin.

In conjunction with STAT1 this pin provides a unique indication for each charging state of the cycle.

This pin is capable to sink 10mA minimum current to drive an LED.

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.
