NAME
FUNCTION
1
3
GATE
Gate of the Internal Power MOSFET. Normally leave open circuit. To slow
down the output voltage ramp, connect two capacitors, one to V
IN
and one to
V
OUT
. See GATE Connections for details.
2
4, 5, 12, 13
V
IN
Voltage Input Terminal. Bypass V
IN
, to AGND with a 0.1礔 capacitor to
improve noise immunity.
3
6
FAULT
Fault Logic Output, open-drain. Tie FAULT to the positive logic supply with a
3.3k& resistor. Referenced to DGND.
4
7
DGND
Digital Ground. Ground reference level for the external positive logic, FAULT,
and ENABLE. DGND can vary up to ?V with respect to AGND to
accommodate differential ground voltages in large systems.
5
10
ENABLE
ENABLE Input. Turns on and off the internal FET. ENABLE is a positive logic-
level input referenced to DGND. Drive ENABLE high to enable V
OUT
. Drive
ENABLE low to disable V
OUT
. Pulse ENABLE low to reset the MAX5911/
MAX5912 after a latched fault condition occurs.
6
11
AGND
Analog Ground. Ground reference level for V
IN
, V
OUT
, and UVLO.

V
OUT
Voltage Output Terminal
8
15
UVLO
Undervoltage Lockout Input. Leave UVLO open circuit for default setting
of -28V. Alternatively, UVLO can be connected to a resistive divider to set the
lockout voltage (see the Changing the Undervoltage Lockout Setting section).
The comparator threshold level is +1.258V with respect to V
IN
.
