NAME
FUNCTION
1
1
RESET
Active-Low Reset Output.
RESET
remains low when V
CC
is below the reset
threshold (V
TH
), the manual-reset input is low, or RESETIN is low. It asserts low in
pulses when the internal watchdog times out.
RESET
remains low for the reset
timeout period (t
RP
) after V
CC
rises above the reset threshold, after the manual-reset
input goes from low to high, after RESETIN goes high, or after the watchdog triggers
a reset event. The MAX160_ _L is an active-low push-pull output, while the
MAX160_ _P is an active-low open-drain output.

CE
IN
Chip-Enable Input. The input to the chip-enable gating circuit. Connect to GND or
OUT if not used.

PFI
GND
Power-Fail Input.
PFO
goes low when V
PFI
falls below 1.235V.
Ground
MR
Manual-Reset Input (MAX16033/MAX16037). Driving
MR
low asserts
RESET
.
RESET
remains asserted as long as
MR
is low and for the reset timeout period (t
RP
) after
MR
transitions from low to high. Leave unconnected, or connect to V
CC
if not used.
MR
has an internal 20k
pullup to V
CC
.
WDI
Watchdog Input (MAX16034/MAX16038
)
. If WDI remains high or low for longer than
the watchdog timeout period (t
WD
), the internal watchdog timer runs out and a reset
pulse is triggered for the reset timeout period (t
RP
). The internal watchdog clears
whenever
RESET
asserts or whenever WDI sees a rising or falling edge (Figure 2).
Battery-On Output (MAX16035/MAX16039). BATTON goes high during battery
backup mode.

RESETIN
Reset Input (MAX16036/MAX16040). When RESETIN falls below 1.235V,
RESET
asserts.
RESET
remains asserted as long as RESETIN is low and for at least t
RP
after RESETIN goes high.
6
5
PFO
Active-Low Power-Fail Output.
PFO
goes low when V
PFI
falls below 1.235V.
PFO
stays low until V
PFI
goes above 1.235V.
PFO
also goes low when V
CC
falls below
the reset threshold voltage.

V
CC
Supply Voltage, 1.2V to 5.5V

7
OUT
Output. OUT sources from V
CC
when
RESET
is not asserted and from the greater of
V
CC
or BATT when V
CC
is below the reset threshold voltage.
9
8
BATT
Backup Battery Input. When V
CC
falls below the reset threshold, OUT switches to
BATT if V
BATT
is 40mV greater than V
CC
. When V
CC
rises above V
BATT
, OUT
switches to V
CC
. The 40mV hysteresis prevents repeated switching if V
CC
falls
slowly.

CE
OUT
Chip-Enable Output.
CE
OUT goes low only when
CE
IN is low and reset is not
asserted. When
CE
OUT is disconnected from
CE
IN,
CE
OUT is actively pulled up to
OUT.
