PRODUCTION DATA
The device monitors the voltage on both the VIN and the VCC pins. If the VCC pin voltage is lower than the VCCUVLO off-threshold voltage, the device shuts off. If the VCC voltage increases beyond the VCCUVLO on-threshold voltage, the device turns back on. VCC UVLO is a non-latch protection.
If the VIN pin voltage is lower than the VINUVLO falling-threshold voltage but VCC pin voltage is still higher than VCCUVLO on-threshold voltage, the device stops switching and discharges SS. If the VIN voltage increases beyond the VINUVLO rising-threshold voltage, the device initiates the soft start and switches again. VIN UVLO is a non-latch protection.
