PB RESET

Push-Button Reset Input. This debounced input ignores pulses of less than 1 ms and is

guaranteed to respond to pulses greater than 20 ms.

TD

Time Delay Set. This input allows the user to select the maximum amount of time that the

ADM1232 allows the STROBE input to remain inactive—that is, STROBE is not receiving any

high-to-low transitions—without forcing the ADM1232 to generate a RESET pulse.

RESET

Active High Logic Output. This pin is asserted when any of the following events occurs:

if there are no high-to-low transitions within the limits set by TD at STROBE; and during power-up.

RESET

Inverse of RESET. This pin has an open-drain output.

STROBE

The STROBE input is used to monitor the activity of a microprocessor. If there are no high-to-low

transitions within the time specified by TD, a reset is asserted.
