GENERAL DESCRIPTION

input and output stage configuration, as shown in table 1.

The ADM6821–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, manual reset

Each part is available in a choice of nine reset threshold options

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

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

The ADM6821–ADM6825 are available in 5-lead SOT-23

packages and typically consume only 3 µA, making them

suitable for use in low power portable applications.
