ADM8322WC26ARJZR7

Processor Supervisor 2.63V 1 Active Low/Push-Pull Automotive 5Pin SOT-23 T/R

Product Details

The ADM8316 / ADM8318 / ADM8319 / ADM8320 / ADM8321 / ADM8322 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 an external push-button switch through a manual reset input. The six devices feature different combinations of watchdog input, manual reset input, and output stage configuration.

Each device is available in a choice of 27 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 minimum and four watchdog timeout options of 6.3 ms, 102 ms, 1.6 sec, and 25.6 sec typical.

The ADM8316 / ADM8318 / ADM8319 / ADM8320 / ADM8321 / ADM8322 are available in 5-lead SOT-23 packages and typically consume only 10 µA, making them suitable for use in low power, portable applications.
