Channel 2 Three-State Current-Sense Range Selection Input. Set the circuit-breaker threshold range by
connecting to DGND, DREG, or leave unconnected.
Channel 1 Three-State Current-Sense Range Selection Input. Set the circuit-breaker threshold range by
connecting to DGND, DREG, or leave unconnected.
Power-Supply Input. Connect to a voltage from 2.7V to 16V. Bypass to AGND with a 1FF capacitor.
Analog Ground. Connect all GND_ and DGND to AGND externally using a star connection.
Internal Regulator Output. Bypass to ground with a 1FF capacitor. Connect only to DREG. Do not use to
power external circuitry.
For normal operation, connect BIAS to REG.

Protection Behavior Input. Three-state input sets one of three different response options for undervoltage
and overvoltage events.
Channel 1 Current-Sense Input. Connect SENSE1 to the source of an external MOSFET and to one end of
R
Channel 1 Voltage Monitoring Input
Channel 1 Gate-Drive Output. Connect to the gate of an external n-channel MOSFET.
Channel 1 Gate Discharge Current Ground Return. Connect all GND_ and DGND to AGND externally
using a star connection.
