PRODUCTION DATA
The BQ2416xx enters the low-power sleep mode if the voltage on VSUPPLY falls below the sleep-mode entry threshold, VBAT+VSLP, and VSUPPLY is higher than the undervoltage lockout threshold, VUVLO. This feature prevents draining the battery during the absence of VSUPPLY. When VSUPPLY < VBAT+ VSLP, the BQ2416xx turns off the PWM converter, turns the battery FET on and drives BGATE to GND, sends a single 128-μs pulse on the STAT and INT outputs and updates the STATx and FAULT_x bits in the status registers. Once VSUPPLY > VBAT+ VSLP, the STATx and FAULT_x bits are cleared and the device initiates a new charge cycle.
