Pin Name Type
Description
MR
Input
Manual-Reset: triggers a reset pulse when pulled below 0.8V, active low. It has an internal 250μA
pull-up current and can be driven from a TTL or CMOS logic line as well as shorted to ground with a
switch.
VCC
Power
Power Supply
GND
Ground
Ground Reference for all signals
PFI
Input
Power-Fail Voltage Monitor Input: When PFI is less than 1.25V, PFO goes low. Connect PFI to GND
or Vcc when not used.
PFO
Output
Power-Fail Output: it gets low and sinks current when PFI is less than 1.25V; otherwise PFO stays
high.
WDI
Input
Watchdog Input: If WDI remains high or low for 1.6sec, the internal watchdog timer runs out and
WDO goes low. Floating WDI or connecting WDI to a high-impedance three-state buffer disables the
watchdog feature. The internal watchdog timer clears whenever reset is asserted, WDI is three-stated,
or WDI sees a rising or falling edge.
NC
No Connect
RESET
Output
Reset Output pulses: low for 200ms when triggered, and stays low whenever Vcc is below the reset
threshold. It remains low for 200ms after VCC rises above the reset threshold or MR goes from low to
high. A watchdog timeout will not trigger RESET unless WDO is connected to MR.
WDO
Output
Watchdog Output: pulls low when the internal watchdog timer finishes its 1.6sec count and does not
go high again until the watchdog is cleared. WDO also goes low during low-line conditions. Whenever
Vcc is below the reset threshold, WDO stays low; however, unlike RESET, WDO does not have mini-
mum pulse width. As soon as VCC rises above the reset threshold, WDO goes high with no delay.
RESET
Output
The inverse of RESET: active high. Whenever RESET is high, RESET is low.
