Pin Description
PIN NAME FUNCTION
1ON
On/Off Control Input. ON is used to implement the undervoltage lockout threshold and resets the part after
a fault condition (see the Detailed Description section).
2FB
Power-Good Comparator Input. Connect a resistive divider from output to FB to GND to monitor the output
voltage (see the Power-Good Detection section). FB is also used as a feedback for the current-limit
foldback function.
3 PWRGD
Open-Drain Power-Good Output. PWRGD is high when V
FB
is higher than V
FBH
. PWRGD is low when V
FB
is lower than V
FBL
.
4 GND Ground
5 TIMER
Timing Input. Connect a capacitor from TIMER to GND to program the maximum time the part is allowed to
remain in current limit (see the TIMER section).
6 GATE Gate-Drive Output. The high-side gate drive for the external n-channel MOSFET (see the GATE section).
7 SENSE
Current-Sense Input. Connect a sense resistor from V
CC
to SENSE and the drain of the external n-channel
MOSFET.
8V
CC
Power-Supply Input. Bypass V
CC
to GND with a 0.1µF capacitor. Input voltage range is from +9V to +80V.
