TOVER/

Open-Drain, Active-Low Output. TOVER goes low when the temperature of the

part exceeds the factory programmed threshold; must use a pull-up resistor.

5

–

TOVER

Push-Pull, Active-High Output. TOVER goes high when the temperature of the

part exceeds the factory programmed threshold.

TUNDER/

Open-Drain, Active-Low Output. TUNDER goes low when the temperature of

the part exceeds the factory programmed threshold; must use a pull-up

resistor.
