FUNCTION

Threshold Window Select Input. SET configures the undervoltage

and overvoltage window range for the internal detectors. Connect

SET to GND for ±5% window, or to VCC for ±10% window. Bias SET

to VCC/2 for a ±15% window.

Undervoltage Output. UV/UV asserts when the monitored supply/

supplies are below the UVTH thresholds or MR is low. UV/UV

deasserts after the specified timeout period when the monitored

supply/supplies rise above the UVTH thresholds or for the specified

propagation delay after MR goes high.

MAX6757/MAX6760: Active-low push-pull output (UV).

MAX6758/MAX6761: Active-high push-pull output (UV).

MAX6759/MAX6762: Active-low open-drain output (UV).

VCC2 Voltage Input. Input for the second window voltage monitor,

and device output power supply when VCC2 > VCC.

Active-Low Overvoltage Output. OV asserts low when the monitored

supply/supplies are above their overvoltage threshold (OVTH). OV

goes high impedance immediately when the monitored supply/

supplies drop below OVTH.

There is no timeout delay period for the OV output.

For MAX6763/MAX6764, OV is low when OVIN is above the internal

0.5V threshold. OV is high when OVIN is below the internal 0.5V

threshold.

MAX6757–MAX6762: Active-low open-drain output.

MAX6763: Active-low push-pull output.

MAX6764: Active-low open-drain output.

Overvoltage Output Latch Control Input. Drive OVLATCH high

to latch the overvoltage output for any VCC or VCC2 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.

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.

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.
