NAME
FUNCTION
15
POL
Polarity Select Input. Connect POL to DREG for an active-high power-good (PG) output, or con-
nect POL to GND for active-low PG output.
16
DREG
Logic Power-Supply Input. Connect to REG externally through a 10I resistor and bypass to
DGND with a 1FF ceramic capacitor.
17
ON
Precision Turn-On Input
18
FAULT
Active-Low Open-Drain Fault Output. FAULT asserts low if an overcurrent event occurs.
19

21
ALERT
Open-Drain Alert Output. ALERT goes low during a fault to notify the system of an impending
failure.
22
PG
Open-Drain Power-Good Output
23, 26, 27,
31, 32
I.C.
Internally Connected. Connect to ground.
24
HWEN
Hardware Enable Input. Connect to REG or DGND. State is read upon power-up as V
IN
 crosses
the UVLO threshold and sets enable register bits with this value. After UVLO, this input becomes
inactive until power is cycled.
25
DGND
Digital Ground. Connect all GND and DGND to AGND externally using a star connection.
28
LED4
LED Driver 4
29
LED3
LED Driver 3
30
GND
Ground

EP
Exposed Pad. EP is internally grounded. Connect EP to the ground plane using a star connection.
