GENERAL DESCRIPTION

The ADM6823/ADM6824/ADM6825 are supervisory circuits

that 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 parts

feature different combinations of watchdog input and manual

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

The ADM6823/ADM6824/ADM6825 are available in 5-lead

SOT-23 packages and typically consume only 7 µA, making

them suitable for use in low power, portable applications.

Each part is available in nine reset threshold options, ranging

from 1.58 V to 4.63 V. The reset and watchdog timeout periods

are fixed at 140 ms (minimum) and 1.6 sec (typical),

respectively.
