Pin Function
Supply: +11V to +50V. Decouple with ≥ 10μF capacitor.
TTL Compatible Input: Logic high turns the external MOSFET on. An internal
pull-down returns an open pin to logic low.
Overcurrent Fault Indicator: When the sense voltage exceeds threshold,
open collector output is open circuit for 5μs (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.
Circuit Ground
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 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.
