Pin Description
PIN
NAME
FUNCTION
1
ON
ON/OFF Control Input. ON is used to implement the undervoltage lockout threshold and resets the part
after a fault condition for the latched-off version (MAX5933A/MAX5933C/MAX5947A, see the Detailed
Description section).
2
FB
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/
PWRGD
Open-Drain Power-Good Output. PWRGD is high (PWRGD is low) when V
FB
is higher than V
FBH
. PWRGD
is low (PWRGD is high) 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- D r i
ve O utp ut. The hi g h- si
d e g ate d r i ve for the exter nal N - channel M OS FE T ( see the G ATE V ol tag e secti on) .
7
SENSE
Current-Sense Input. Connect a sense resistor from V
CC
to SENSE and the drain of the external n-channel
MOSFET.
8
V
CC
Power-Supply Input. Bypass V
CC
to GND with a 0.1礔 capacitor. Input voltage range is from +9V to +80V
for the MAX5947A/B/C. Input voltage range is from +33V to +80V for the MAX5933AMAX5933F.
