2-6. Undervoltage lockout (UVLO)

Figure 2.6 Undervoltage lockout (UVLO)

When the input voltage of a load switch IC drops below the internal threshold, the undervoltage lockout (UVLO) function turns off its output to ensure system stability. This function comes in handy because system operation might become unstable if the voltage supplied to a constituent IC or circuit drops. Undervoltage lockout has a hysteresis. When the input voltage rises back above the recovery threshold, the output automatically turns back on.
