PRODUCTION DATA
The IC provides a recovery method to deal with timer fault conditions. The following summarizes this method:
Condition 1: The battery voltage is above the recharge threshold and a time-out fault occurs.
Recovery Method: The timer fault will clear when the battery voltage falls below the recharge threshold, and battery detection will begin. A POR or taking ISET below 40 mV will also clear the fault.
Condition 2: The battery voltage is below the recharge threshold and a time-out fault occurs.
Recovery Method: Under this scenario, the IC applies the fault current to the battery. This small current is used to detect a battery removal condition and remains on as long as the battery voltage stays below the recharge threshold. If the battery voltage goes above the recharge threshold, the IC disabled the fault current and executes the recovery method described in Condition 1. A POR or taking ISET below 40 mV will also clear the fault.
