Manual Reset Input forces RESET to assert when pulled below 0.8V.
An internal pull-up current of 250
μ
A on this input forces it high when left
floating. This input can also be driven from TTL or CMOS logic.
Primary supply input, +5V.
IC ground pin, 0V reference.
Power fail input. Internally connected to the power fail comparator
which is referenced to 1.25V. The power fail output (PFO) remains
high if PFI is above 1.25V. PFI should be connected to GND or VOUT
if the power fail comparator is not used.
Power fail output. The power fail comparator is independent of all other
functions on this device.
Watchdog input. The WDI input monitors microprocessor activity, an
internal watchdog timer resets itself with each transition on the
watchdog input. If the WDI pin is held high or low for longer than the
watchdog timeout period, WDO is forced to active low. The watchdog
function can be disabled by floating the WDI pin.
No Connect
RESET is asserted if either VCCgoes below the reset threshold or by a
low signal on the manual reset input (MR). RESET remains asserted
for one reset timeout period (200ms) after VCCexceeds the reset
threshold or after the manual reset pin transitions from low to high. The
watchdog timer will not assert RESET unless WDO is connected to
MR.
Output for the watchdog timer. The watchdog timer resets itself with
each transition on the watchdog input. If the WDI pin is held high or
low for longer than the watchdog timeout period, WDO is forced low.
WDO will also be forced low if VCCis below the reset threshold and
will remain low until VCCreturns to a valid level.
RESET is the compliment of RESET and is asserted if either VCCgoes
below the reset threshold or by a low signal on the manual reset input
(MR). RESET is suitable for microprocessors systems that use an
active high reset.
Pin No.
