NAME FUNCTION
7 — OVLATCH
Overvoltage Output Latch Control Input. Drive OVLATCH high to latch
the overvoltage output for any V
CC or V CC2 overvoltage condition. Drive
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.
— — — 3 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.
— — — 6 OVIN
Overvoltage Input. OV is low when OVIN is above the internal 0.5V
threshold. OV is high when OVIN is below the internal 0.5V threshold.
— — EP — EP
Exposed Pad. EP is internally connected to GND. Leave EP
unconnected or connect to GND.
