NAME
FUNCTION
1
PGOOD
Open-Drain Status Output. High impedance when startup is complete and no faults
are detected. Actively held low during startup and when a fault is detected.
2
TIM
Startup Timer Setting. Connect a resistor from TIM to GND to set the startup period.
Leave TIM unconnected for the default startup period of 9ms.
1
3
IN1
Channel 1 Supply Input. Connect to a supply voltage from 1V to 13.2V. Connect a
0.1礔 ceramic bypass capacitor from IN1 to GND to filter high-frequency noise.
2
4
SENSE1
Channel 1 Current-Sense Input. Connect R
SENSE1
from IN1 to SENSE1.
3
5
GATE1
Channel 1 Gate-Drive Output. Connect to gate of external n-channel MOSFET.
4
6
GND
Ground
7
LIM1
Channel 1 Current-Limit Setting. Connect a resistor from LIM1 to GND to set
current-trip level. Connect to GND for the default 25mV threshold.
8
MON1
Channel 1 Output Voltage Monitor. Window comparator input. Connect through a
resistive-divider from OUT1 to GND to set the channel 1 overvoltage and
undervoltage thresholds. Connect to IN1 to disable.
9
MON2
Channel 2 Output Voltage Monitor. Window comparator input. Connect through a
resistive-divider from OUT2 to ground to set the channel 2 overvoltage and
undervoltage thresholds. Connect to IN2 to disable.
