APPLICATION INFORMATION
SUPPLY VOLTAGE MONITOR
Reset Signal Polarity and Output Stage Structure
RESET
¯¯¯¯¯¯ is an active LOW signal. It is developed with
an open drain driver in the CAT1232LP. A pull-up
resistor is required, typical values are 10 kΩ to 50 kΩ.
The CAT1832 uses a CMOS push-pull output stage
for the RESET
¯¯¯¯¯¯.
RESET is an active High signal developed by a
CMOS push-pull output stage and is the logical
opposite to RESET
¯¯¯¯¯¯.
Trip Point Tolerance Selection
The TOL input is used to select the VCC trip point
threshold. This selection is made connecting the
TOL input to ground or V
CC. Connecting TOL to
Ground makes the V
CC trip threshold 4.62 V for the
CAT1232LP and 2.88 V for the CAT1832.
Connecting TOL to V
CC makes the VCC trip threshold
4.37 V for the CAT1232LP and 2.55 V for the
CAT1832.
After VCC has risen above the trip point set by TOL,
RESET and RESET
¯¯¯¯¯¯remain active for a minimum time
period of 250 ms.
On power-down, once V
CC
falls below the reset
threshold the RESET outputs will remain active and
are guaranteed valid down to a V
CC level of 1.0 V.

Manual Reset Operation
Push-button input, PBRST
¯¯¯¯¯¯, allows the user to issue
reset signals. The pushbutton input is debounced and
is pulled high through an internal 40 kΩ resistor.
When PBRST
¯¯¯¯¯¯ is held low for the minimum time of
20 ms, both resets become active and remain active
for a minimum time period of 250 ms after PBRST
returns high.
No external pull-up resistor is required, since PBRST
¯¯¯¯¯¯
is pulled high by an internal 40 kΩ resistor.
PBRST
¯¯¯¯¯¯ can be driven from a TTL or CMOS logic line
or short-ed to ground with a mechanical switch.
