PRODUCTION DATA.
The converter does not allow the high-side FET to turn on until the BAT voltage goes below 102% of the regulation voltage. This allows one-cycle response to an overvoltage condition, such as occurs when the load is removed or the battery is disconnected. An 8-mA current sink from SRP to GND is on only during charge and allows discharging the stored output inductor energy that is transferred to the output capacitors. BATOVP also suspends the safety timer.
