NAME
FUNCTION
1
4
IN1
Channel 1 Supply Input. Connect to a supply voltage from 1V to 15V and to one end of
R
SENSE1
. Bypass with a 0.1礔 capacitor to ground.
2
5
SENSE1
Channel 1 Current-Sense Input. Connect SENSE1 to the drain of an external MOSFET
and to one end of R
SENSE1
.
3
6
GATE1
Channel 1 Gate-Drive Output. Connect to gate of external n-channel MOSFET.
4

LIM4
Channel 4 Current-Limit Setting. Connect a resistor from LIM4 to GND to set current-trip
level. Connect to GND for the default 25mV threshold. Do not leave unconnected.
5
7
IN4
Channel 4 Supply Input. Connect to a supply voltage from 1V to 15V and to one end of
R
SENSE4
. Bypass with a 0.1礔 capacitor to ground.
6
8
SENSE4
Channel 4 Current-Sense Input. Connect SENSE4 to the drain of an external MOSFET
and to one end of R
SENSE4
.
7
9
GATE4
Channel 4 Gate-Drive Output. Connect to gate of external n-channel MOSFET.

10
STAT1
Open-Drain Status Signal for Channel 1. STAT1 asserts when hot swap is successful and
t
START
 has elapsed. STAT1 deasserts if ON1 is low, or if channel 1 is turned off for any
fault condition.
9
11
STAT2
Open-Drain Status Signal for Channel 2. STAT2 asserts when hot swap is successful and
t
START
 has elapsed. STAT2 deasserts if ON2 is low, or if channel 2 is turned off for any
fault condition.
10
12
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. R
TIM
 must be between
4k?and 500k?
11, 20

N.C.
No Connection. Not internally connected.
12

LATCH
Latch/Autoretry Selection Input. Connect LATCH to GND for autoretry mode after a fault.
Leave LATCH unconnected for latch mode.
13
13
STAT3
Open-Drain Status Signal for Channel 3. STAT3 asserts when hot swap is successful and
t
START
 has elapsed. STAT3 deasserts if ON3 is low, or if channel 3 is turned off for any
fault condition.
14
14
STAT4
Open-Drain Status Signal for Channel 4. STAT4 asserts when hot swap is successful and
t
START
 has elapsed. STAT4 deasserts if ON4 is low, or if channel 4 is turned off for any
fault condition.
15
15
BIAS
Supply Reference Output. The highest supply is available at BIAS for filtering. Connect a
1nF to 10nF ceramic capacitor from BIAS to GND. No other connections are allowed to
this pin.
16
16
GND
Ground
17
17
GATE3
Channel 3 Gate-Drive Output. Connect to gate of external n-channel MOSFET.
18
18
SENSE3
Channel 3 Current-Sense Input. Connect SENSE3 to the drain of an external MOSFET
and to one end of R
SENSE3
.
19
19
IN3
Channel 3 Supply Input. Connect to a supply voltage from 1V to 15V and to one end of
R
SENSE3
.
21

LIM3
Channel 3 Current-Limit Setting. Connect a resistor from LIM3 to GND to set current-trip
level. Connect to GND for the default 25mV threshold. Do not leave unconnected.
