Power
Type
Device power supply. Requires bypass capacitor of 10 µF in parallel with 0.1
µF and 100 pF. Place 100 pF closest to device pin.
Critical temperature output. Open-drain output requires pull-up resistor.
Active “LOW”.
Device ground.
Over-temperature shutdown comparator output or SMBus slave address
input. Defaults as an SMBus slave address input that selects one of three
addresses. Can be tied to V
connected between V
output it is active “Low” and open drain.
