SLVSCM8C May 2015 – February 2019 TPS61088
The UVLO circuit prevents the device from malfunctioning at low input voltage and the battery from excessive discharge. The TPS61088 has both VIN UVLO function and VCC UVLO function. It disables the device from switching when the falling voltage at the VIN pin trips the UVLO threshold VIN_UVLO , which is typically 2.4 V. The device starts operating when the rising voltage at the VIN pin is 200-mV above the VIN_UVLO. It also disables the device when the falling voltage at the VCC pin trips the UVLO threshold VCC_UVLO, which is typically 2.1 V.
