GENERAL DESCRIPTION

The ADM6316/ADM6317/ADM6318/ADM6319/ADM6320/

ADM6321/ADM6322 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 seven

parts feature different combinations of watchdog input, manual

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

infringements of patents or other rights of third parties that may result from its use.

Specifications subject to change without notice. No license is granted by implication

or otherwise under any patent or patent rights of Analog Devices. Trademarks and

registered trademarks are the property of their respective owners.

Each part is available in a choice of 26 reset threshold options

ranging from 2.5 V to 5 V in 100 mV increments. There are also

four reset timeout options of 1 ms, 20 ms, 140 ms, and 1120 ms

(min) and four watchdog timeout options of 6.3 ms, 102 ms,

1600 ms, and 25.6s (typ).

The ADM6316-ADM6322 are available in 5-lead SOT-23

packages and typically consume only 3 µA, making them

suitable for use in low power portable applications.
