FUNCTIONAL DESCRIPTION
Processor RESET
The CAT823 ? 825 detect supply voltage (V CC ) conditions
that are below the specified voltage trip value (V RST ) and
provide a reset output to maintain correct system operation.
On power ? up, RESET (and RESET if available) are kept
active for a minimum delay t RP of 140 ms after the supply
voltage (V CC ) rises above V RST to allow the power supply
and processor to stabilize. When V CC drops below the
voltage trip value (V RST ), the reset output signals RESET
(and RESET) are pulled active. RESET (and RESET if
available) is specifically designed to provide the reset input
signals for processors. This provides reliable and consistent
operation as power is turned on, off or during brownout
conditions by maintaining the processor operation in known
conditions.
MR
Manual RESET
The CAT823 and CAT825 each have a Manual Reset
(MR) input to allow for alternative control of the reset
outputs. The MR input is designed for direct connection to
a pushbutton (see Figure 4). The MR input is internally
pulled up by 52 k W resistor and must be pulled low to cause
the reset outputs to go active. Internally, this input is
debounced and timed such that RESET (and RESET)
signals of at least 140 ms minimum will be generated. The
min 140 ms t RP delay commences as the Manual Reset input
is released from the low level. (see Figure 5)
