7.3.1 Undervoltage Lockout

The undervoltage lockout (UVLO) circuit disables the power switch until the input voltage reaches the UVLO turnon threshold. Built-in hysteresis prevents unwanted ON/OFF cycling due to input voltage drop from large current surges. FLT is high impedance when the TPS20xxC and TPS20xxC-2 are in UVLO.
