with 10-Bit Current and Voltage Monitor
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 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.
Channel 3 Gate Discharge Current Ground Return. Connect all GND_ and DGND to AGND externally
using a star connection.
Channel 3 Gate-Drive Output. Connect to the gate of an external n-channel MOSFET.
Channel 3 Voltage Monitoring Input
Channel 3 Current-Sense Input. Connect SENSE3 to the source of an external MOSFET and to one end of
R
Polarity Select Input. Connect to DREG for active-high power-good outputs (PG_). Connect to GND_ for
active-low power-good outputs.
Logic Power-Supply Input. Connect to REG externally through a 10Ω resistor and to DGND with a 1µF
ceramic capacitor.
Channel 1 Precision Turn-On Input
Channel 3 Precision Turn-On Input
Channel 1 Active-Low Open-Drain Fault Output. FAULT1 goes low if an overcurrent shutdown occurs on
channel 1.
Channel 2 Active-Low Open-Drain Fault Output. FAULT2 goes low if an overcurrent shutdown occurs on
channel 2.
Channel 3 Active-Low Open-Drain Fault Output. FAULT3 goes low if an overcurrent shutdown occurs on
channel 3.
Channel 4 Active-Low Open-Drain Fault Output. FAULT4 goes low if an overcurrent shutdown occurs on
channel 4.
