DD
Input
Supply: +11V to +50V. Decouple with
≥

μ
F capacitor.
2
TTL Compatible Input: Logic high turns the external MOSFET on. An internal
pull-down returns an open pin to logic low.
3
Fault
Overcurrent Fault Indicator: When the sense voltage exceeds threshold,
open collector output is open circuit for 5
μ
s (t
G(ON)
), then pulled low for
t
G(OFF)
. t
G(OFF)
is adjustable from C
T
.
Retry Timing Capacitor: Controls the off time (t
G(OFF)
) of the overcurrent
retry cycle. (Duty cycle adjustment.)
Open = 20% duty cycle.
Capacitor to Ground = approx. 20% to <1% duty cycle.
Pull-Up resistor = approx. 20% to approx. 75% duty cycle.
Ground = maintained shutdown upon overcurrent condition.

Sense +
Current Sense Comparator (+) Input: Connect to high side of sense resistor
or current sensing MOSFET sense lead. A built-in offset in conjunction with
R
SENSE
sets the load overcurrent trip point.
Current Sense Comparator (–) Input: Connect to the low side of the sense
resistor (usually power ground).

Gate
Gate Drive: Drives the gate of an external power MOSFET. Also limits V
GS
to 15V max. to prevent Gate to Source damage. Will sink and source
current.
