NAME
FUNCTION
Supply Output for CMOS RAM. When V CC is above the reset threshold,

V OUT
V OUT connects to V CC through a P-channel MOSFET switch. When V CC
is below the reset threshold, the higher of V CC or V BATT will be
connected to V OUT .

Power-Fail Comparator Input. When PFI is less than 1.25V, PFO goes
low. Connect PFI to GND or V CC when not used.
Power-Fail Output. When PFI is less than 1.25V, PFO goes low;
otherwise PFO stays high.
Watchdog Input. If WDI remains high or low for 1.6sec, the internal
watchdog timer runs out and reset is triggered. If WDI is left floating or

WDI
connected to a high-impedance three-state buffer, the watchdog
feature is disabled. The internal watchdog timer clears whenever reset
is asserted, WDI is three-stated, or WDI sees a rising or falling edge.
Reset Output. Whenever RESET is triggered, it pulses low for 200ms. It

stays low when V CC is below the reset threshold (4.65V in the
MAX690A/MAX802L and 4.4V in the MAX692A/MAX802M) and remains
low for 200ms after V CC rises above the reset threshold. A watchdog
timeout also triggers RESET .
Active-High Reset Output is the inverse of RESET . When RESET is

asserted, the RESET output voltage = V CC or V BATT , whichever is
higher.
Backup-Battery Input. When V CC falls below the reset threshold, V BATT

will be switched to V OUT if V BATT is 20mV greater than V CC . When V CC
rises to 20mV above V BATT , V OUT will be reconnected to V CC . The 40mV
hysteresis prevents repeated switching if V CC falls slowly.
