GENERAL DESCRIPTION

Each part is available in a choice of seven reset threshold

options ranging from 2.19 V to 4.63 V. The reset and watchdog

timeout periods are fixed at 140 ms (min) and 1.6s (typ),

respectively.

The ADM823/ADM824/ADM825 are supervisory circuits

which monitor power supply voltage levels and code execution

integrity in microprocessor-based systems. As well as providing

power on reset signals, an on-chip watchdog timer can reset the

microprocessor if it fails to strobe within a preset timeout

period. A reset signal can also be asserted by means of an

external push-button, through a manual reset input. The three

parts feature different combinations of watchdog input, manual

reset input and output stage configuration, as shown in Table 1.

The ADM823/ADM824/ADM825 are available in 5-lead SC70

and SOT-23 packages and typically consume only 3 µA, making

them suitable for use in low power portable applications.
