7.3.5 Overvoltage Lockout (OVLO)

The series pass MOSFET (Q1) is enabled when the input supply voltage (VSYS) is within the operating range defined by the programmable undervoltage lockout (UVLO) and overvoltage lockout (OVLO) levels. If VSYS raises the OVLO pin voltage above 2.5 V, Q1 is switched off by the 2-mA pulldown current at the GATE pin, denying power to the load. When the OVLO pin is above 2.5 V, the internal 21-µA current source at OVLO is switched on, raising the voltage at OVLO to provide threshold hysteresis. When VSYS is reduced below the OVLO level Q1 is enabled. See Application and Implementation for a procedure to calculate the threshold setting resistor values.
