OVLATCH

Overvoltage Output Latch Control Input. Drive OVLATCH high to latch

OVLATCH low to clear the latch after overvoltage conditions have been

removed. The latch is transparent when OVLATCH is connected to

GND. OVLATCH is a high-impedance input. Use external pullup or

pulldown.

UVIN

Undervoltage Input. UV is low when UVIN is below the internal 0.5V

threshold. UV is high when UVIN is above the internal 0.5V threshold.

4

UV

Undervoltage Output. UV is low when UVIN is below the internal 0.5V

threshold. UV is high when UVIN is above the internal 0.5V threshold.

There is no timeout delay period for the UV output.
