Pin Description
Backup-Battery Input. When VCC falls below the reset threshold, BATT switches to OUT if VBATT is 20mV
greater than VCC. When VCC rises 20mV above VBATT, VCC switches to OUT. The 40mV hysteresis
prevents repeated switching if VCC falls slowly.
BATT
6
Supply Voltage, 0 to 5.5V. Reset is asserted when VCC drops below the reset threshold voltage (VTH).
Reset remains asserted until VCC rises above VTH and for at least 150ms after VCC rises above VTH.
VCC
4
Output. OUT sources from VCC when it is above the reset threshold (VTH), and from the greater of VCC or
BATT when VCC is below VTH.

PIN
Active-Low Reset Output. RESET is continuously low when VCC is below the reset threshold (VTH), MR is
low, or RESET IN is low. It asserts in pulses when the internal watchdog times out. RESET remains low for
the reset timeout period (tRP) after VCC rises above the reset threshold, after the manual reset input goes
from low to high, after RESET IN goes high, or after the watchdog triggers a reset event. The MAX636_L
is an active-low push-pull output while the MAX636_P is an active-low open-drain output.
RESET
Active-High Reset Output. RESET is continuously high when VCC is below the reset threshold (VTH), MR is
low, or RESET IN is low. It asserts in pulses when the internal watchdog times out. RESET remains high
for the reset timeout period (tRP) after VCC rises above the reset threshold, after the manual reset input
goes from low to high, after RESET IN goes high, or after the watchdog triggers a reset event. The
MAX636_H is an active-high open-drain output.

MAX6361 Manual-Reset Input. Maintaining logic low on MR asserts a reset. Reset output remains assert-
ed for at least 150ms (tRP) after MR transitions from low to high. Leave unconnected or connected to VCC
if not used.

MAX6364 Reset Input. When RESET IN falls below 1.235V, reset is asserted. Reset output remains
asserted as long as RESET IN is low and for at least 150ms (tRP) after RESET IN goes high.
MAX6363 Battery-On Output. BATT ON goes high in battery backup mode.
MAX6362 Watchdog Input. If WDI remains high or low for longer than the watchdog timeout period (tWD), the
internal watchdog timer runs out and a reset pulse is triggered for the reset timeout period (tRP) (Figure 1). The
internal watchdog clears whenever reset asserts or whenever WDI sees a rising or falling edge.
