PIN FUNCTION DESCRIPTIONS
Function
Push Button Reset Input. This debounced input will ignore pulses of less than 1 ms and is guaranteed to re-
spond to pulses greater than 20 ms.
Time Delay Set allows the user to select the maximum amount of time the ADM1232A will allow the STROBE
input to remain inactive (i.e., STROBE is not receiving any high-to-low transitions), without forcing the
ADM1232A to generate a RESET pulse. (See STROBE specifications, Figure 4 and the note on STROBE
timeout selection.)
Tolerance Input. This 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 VCC for 10% and GND for 5%.
0 V ground reference for all signals.
Active high logic output. Will be asserted when:
1. VCC decreases below the amount specified by the TOLERANCE input or,
2. PB RESET is forced low or,
3. If there are no high-to-low transitions within the limits set by TD at STROBE or,
4. During power-up.
Inverse of RESET, with an open drain output.
The 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 TD, a reset will be asserted.
Power supply input +5 V.
