A series RC network from the GATE to the VIN pin is
required to control the slew rate at the VIN pin when the
switch is turned on or off. The slew rate control prevents
excessive current from the capacitor usually located in the
wall adapter from flowing into the battery when the pass
transistor turns on.
BAT (Pin 8): Battery Sense Input Pin. An internal resistor
divider presets the final float voltage to 4.2V. If the BAT pin
drops below 4.05V after the charge cycle has ended, the
timer resets and a new charge cycle begins. This pin is
clamped to 4.7V if the battery is disconnected while
charging.
