Supply Voltage Input. IN is connected to the drain of the internal 24mI MOSFET. Bypass IN with
1FF capacitor to ground. Add a transient voltage suppressor diode from IN to GND for output
short-circuit protection.
Fault Status Output. FAULT is an open-drain, active-low output. FAULT asserts low when an over-
current or overtemperature condition triggers a shutdown.
Power-Good Output. PG is an open-drain, active-high output. PG pulls low until the internal power
MOSFET is fully enhanced.
Load Connection Point. Source of the internal power MOSFET.
Active-Low Present-Detect Logic Input. Pulling PRESDET to GND enables the output if ON2 is low
and ON1 is high.
Active-Low Enable Logic Input. Pulling ON2 to GND enables the output if PRESDET is low and
ON1 is high.
Current-Limit Threshold Set. Connect a resistor from CB to GND to set the circuit-breaker threshold.
Internal Regulator Output. Bypass to ground with a 1FF capacitor. Do not power external circuitry
using the REG output.
Active-High Enable Comparator Input. Pulling ON1 high enables the output if PRESDET and
ON2 are held low. ON1 also sets the undervoltage threshold. See the Setting the Undervoltage
Threshold section.
Exposed Pad. EP is internally grounded. Connect externally to ground plane for effective heat dis-
sipation. Do not use as the only ground connection.
