WDS1
Min/Max Watchdog Logic-Select Input. WDS0 and WDS1 select the watchdog
window ratio or disable the watchdog timer. Drive WDS0 and WDS1 high or

WDS0
low to select the desired ratio, see Table 4.
Watchdog Input.
MAX6793 –MAX6796: A falling or rising transition must occur on WDI within the
selected watchdog timeout period or a reset pulse occurs. The watchdog timer
clears when a transition occurs on WDI or whenever RESET is asserted.

WDI
MAX6791/MAX6792: WDI falling and rising transitions within periods shorter
than t WD1 or longer than t WD2 force RESET to assert low for the reset timeout
period. The watchdog timer begins to count after RESET is deasserted. The
watchdog timer clears when a valid transition occurs on WDI or whenever
RESET is asserted. Connect WDS0 high and WDS1 low to disable the watchdog
timer function. See the Watchdog Timer section.
Active-Low Regulator Hold Input. When HOLD is forced low, OUT1/OUT
remains ON even if ENABLE1/ENABLE is pulled low. To shut down the
12

HOLD
output of the regulator (OUT/OUT1), release HOLD after ENABLE1/ENABLE is
pulled low. Connect HOLD to OUT1/OUT or leave unconnected if unused.
HOLD is internally connected to OUT/OUT1 through a 2μA current source.

OUT2
ENABLE2
Regulator 2 Output. OUT2 is a fixed +5V output. Connect a 10μF (min)
capacitor from OUT2 to GND.
Active-High Enable Input 2. Drive ENABLE2 high to turn on OUT2. ENABLE2
is internally connected to ground through a 0.5μA current sink.
Adjustable Power-Fail Comparator Input. Connect PFI to a resistive-divider to

PFI
set the desired PFI threshold. The PFI input is referenced to an accurate
1.231V threshold.

Regulator Inputs. Bypass IN with a 1μF capacitor to GND.
pFET Gate Drive. Connect GATEP to the gate of a p-channel MOSFET to
provide low drop reverse-battery voltage protection.
Active-High Enable Input 1. Drive ENABLE1 high to turn on OUT1. ENABLE1
is internally connected to ground through a 0.5μA current sink.
Watchdog Disable Input. Drive WD-DIS low to disable the watchdog timer.

WD-DIS
Drive WD-DIS high or connect to OUT/OUT1 to enable the watchdog timer.
The watchdog timer clears when reset asserts.
