NAME
FUNCTION
1

1
V
CC
Power-Supply Input. Connect V
CC
 to a voltage between 2.47V and 13.2V.
V
CC
 must always be equal to or greater than V
S
 (see Figure 1).

SC_DET
Short-Circuit Detection Output. Connect SC_DET to V
OUT
 through a series
resistor, R
SC
, when not using R
SENSE
. SC_DET forces current (limited to
H200mA) into the external load through R
SC
 at startup to determine whether
there is a short circuit (load probing). Connect SC_DET directly to V
CC
 
when
using R
SENSE
, Do not connect SC_DET to V
CC
 when not using R
SENSE
 in an
attempt to disable load probing.

EN
ON/OFF Control Input. Drive EN high to enable the device. Drive EN low to
disable the device. An optional external resistive-divider connected between
V
CC
, EN, and GND sets the programmable turn-on voltage.

SLEW
Slew-Rate Adjustment Input. Connect an external capacitor between SLEW and
GND to adjust the gate slew rate. Leave SLEW unconnected for the default
slew rate.

GATE
Gate-Drive Output. Connect GATE to the gate of the external n-channel
MOSFET.

OUT
Output Voltage. Connect OUT to the source of the external MOSFET.

15
SENSE
Circuit-Breaker Sense Input. Connect SENSE to OUT when not using an
external R
SENSE
 (Figure 1). Connect SENSE to the drain of the external
MOSFET when using an external R
SENSE
 (Figure 2).

16
CB
Circuit-Breaker Threshold Programming Input. Connect an external resistor,
R
CB
, from CB to V
S
 to set the circuit-breaker threshold voltage.


3
EN1
Active-High ON/OFF Control Input. Drive EN1 high to enable the device when
EN2 is low. Drive EN1 low to disable the device, regardless of the state of EN2.
An optional external resistive-divider between V
CC
, EN1, and GND sets the
programmable turn-on voltage while EN2 is low.


6
EN2
Active-Low ON/OFF Control Input. Drive EN2 low to enable the device when
EN1 is high. Drive EN2 high to disable the device, regardless of the state of
EN1.


8
LATCH
Latch Mode Input. Drive LATCH low for autoretry mode. Drive LATCH high for
latched mode.


9
TC
Circuit-Breaker Temperature Coefficient Selection Input. Drive TC low to select
a 3300ppm/癈 temperature coefficient. Drive TC high to select a 0ppm/癈
temperature coefficient.

N.C.
No Connection. Not internally connected.


EP
EP
Exposed Pad. Connect EP to GND.
