Analog Devices Inc. ADM8321 Supervisory Circuit
Analog Devices Inc. ADM8321 Supervisory Circuit monitors 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 an external push-button switch through a manual reset input.
The ADI ADM8321 Supervisory Circuit features a watchdog input, output stage configuration (open-drain and push-pull). This device comes with a reset threshold of 3.0V, a reset timeout of 1ms (minimum) and a timeout of 1.6sec (typical). It comes in a 5-lead SOT-23 package and typically consumes only 10μA, making it suitable for use in low power, portable applications.
