The converter will not allow the high-side FET to turn on until the battery voltage goes below 102% of the regulation voltage. This allows 1-cycle response to an overvoltage condition – such as occurs when the load is removed or the battery is disconnected. A total 6 mA current sink from SRP/SRN to AGND allows discharging the stored output inductor energy that is transferred to the output capacitors. If battery overvoltage condition lasts for more than 30 ms, charge is disabled.
