PRODUCTION DATA.
The BQ2461x 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 timeout fault occurs.
Recovery Method: The timer fault clears when the battery voltage falls below the recharge threshold, and battery detection will begin. Taking CE low or a POR condition also clears the fault.
Condition 2: The battery voltage is below the recharge threshold and a timeout fault occurs.
Recovery Method: Under this scenario, the BQ2461x applies the IFAULT 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 BQ2461x disables the fault current and executes the recovery method described in Condition 1. Taking CE low or a POR condition also clears the fault.
