Function
PB RESET
Push Button Reset Input. T his debounced input will ignore pulses of less than 1 ms and is guaranteed to re-
spond to pulses greater than 20 ms.
T ime Delay Set allows the user to select the maximum amount of time the ADM1232 will allow the
STROBE
input to remain inactive (i.e.,
STROBE
is not receiving any high-to-low transitions), without forcing the
ADM1232 to generate a RESET pulse. (See
STROBE
specifications, Figure 4 and the note on
STROBE
timeout selection.)
T olerance Input. T his input will determine how much the supply voltage will be allowed to decrease (as a per-
centage tolerance) before a RESET is asserted. Connect to V
CC
for 10% and GND for 5%.
0 V ground reference for all signals.
Active high logic output. Will be asserted when:
1. V
CC
decreases below the amount specified by the T OLERANCE input or,
2.
PB RESET
is forced low or,
3. If there are no high-to-low transitions within the limits set by T D at
STROBE
or,
4. During power-up.
Inverse of RESET , with an open drain output.
T he
STROBE
input is used to monitor the activity of a microprocessor. If there are no high-to-low transi-
tions within the time specified by T D, a reset will be asserted.
Power supply input +5 V.
