NAME

FUNCTION

OVOUT2

Active-Low Overvoltage Output 2. When the voltage at OVIN2 rises above its threshold, OVOUT2 asserts

low and stays asserted until the voltage at OVIN2 falls below its threshold. The open-drain output has a

16

UVOUT2

Active-Low Undervoltage Output 2. When the voltage at UVIN2 falls below its threshold, UVOUT2 asserts

low and stays asserted until the voltage at UVIN2 exceeds its threshold. The open-drain output has a 30µA

17

OVOUT1

Active-Low Overvoltage Output 1. When the voltage at OVIN1 rises above its threshold, OVOUT1 asserts

low and stays asserted until the voltage at OVIN1 falls below its threshold. The open-drain output has a

18

UVOUT1

Active-Low Undervoltage Output 1. When the voltage at UVIN1 falls below its threshold, UVOUT1 asserts

low and stays asserted until the voltage at UVIN1 exceeds its threshold. The open-drain output has a 30µA

19

RESET

Active-Low Reset Output. RESET asserts low when the voltage on any of the UVIN_ inputs falls below their

respective thresholds, the voltage on any of the OVIN_ inputs goes above its respective threshold, or MR is

asserted. RESET remains asserted for at least the minimum reset timeout after all monitored UVIN_ inputs

exceed their respective thresholds, all OVIN_ inputs fall below their respective thresholds, and MR is

deasserted. This open-drain output has a 30µA internal pullup.

20

UVIN1

Undervoltage Threshold Input 1. When the voltage on UVIN1 falls below its threshold, UVOUT1 asserts low.

21

OVIN1

Overvoltage Threshold Input 1. When the voltage on OVIN1 rises above its threshold, OVOUT1 asserts low.

22

UVIN2

Undervoltage Threshold Input 2. When the voltages on UVIN2 falls below its threshold, UVOUT2 asserts

low.

23

OVIN2

Overvoltage Threshold Input 2. When the voltage on OVIN2 rises above its threshold, OVOUT2 asserts low.

—EP

Exposed Pad. EP is internally connected to GND. Connect EP to the ground plane to provide a low thermal

resistance path from the IC junction to the PCB. Do not use as the only electrical connection to GND.
