NAME
FUNCTION
1
IRNG
Three-State Current-Sense Range Selection Input. Set the circuit-breaker threshold range by
connecting to DGND, DREG, or leave unconnected.
2
IN
Power-Supply Input. Connect to a voltage from 2.7V to 16V. Bypass IN to AGND with a 1FF
ceramic capacitor.
3
AGND
Analog Ground. Connect all GND and DGND to AGND externally using a star connection.
4
REG
Internal Regulator Output. Bypass REG to ground with a 1FF ceramic capacitor. Connect only to
DREG and logic-input pullup resistors. Do not use to power external circuitry.
5
BIAS
BIAS Input. Connect BIAS to REG.

PROT
Protection Behavior Input. Three-state input sets one of three different response options for
undervoltage and overvoltage events.
9
SENSE
Current-Sense Input. Connect SENSE to the source of an external MOSFET and to one end of
R
SENSE
.
10
MON
Voltage-Monitoring Input
11
GATE
Gate-Drive Output. Connect to the gate of an external n-channel MOSFET.
12
GND
Gate-Discharge Current Ground Return. Connect all GND and DGND to AGND externally using
a star connection.
