9.3.2 Undervoltage Lockout (UVLO)

The TPS1663x devices feature an accurate ± 2% adjustable undervoltage lockout functionality. When the voltage

at UVLO pin falls below V(UVLOF) during input undervoltage fault, the internal FET quickly turns off and FLT is

asserted. The UVLO comparator has a hysteresis of 78 mV (typical). To set the input UVLO threshold, connect a

resistor divider network from IN supply to UVLO terminal to GND as shown in Figure 17. If the Under-Voltage

Lock-Out function is not needed, the UVLO terminal must be connected to the IN terminal. UVLO terminal must

not be left floating.
