    Hi,

    Almost all of our BQ77915xx devices require load removal to recover from certain faults. This is detected by measuring the voltage on the LD pin. If the voltage on the LD pin is less than VLDT (approximately 1.3V), then the device will recognize that the load has been removed. If VLD is greater than VLDT, the device will recognize that there is a load present.
