The ADM8616/ADM8617 are supervisory circuits that monitor power supply voltage levels and code execution integrity in micro- processor-based systems. A power-on reset signal generates when the supply voltage rises to a preset threshold level. The ADM8616/ADM8617 have an on-chip watchdog timer that can reset the microprocessor if it fails to strobe within a preset timeout period.
Each part is available in the following nine reset threshold options: 1.58 V, 1.67 V, 2.19 V, 2.32 V, 2.63 V, 2.93 V, 3.08 V, 4.38 V, and 4.63 V. There are four reset timeout options: 1 ms, 20 ms, 140 ms, and 1120 ms. There are also three possible watchdog timeouts available: 6.3 ms, 102 ms, and 1.6 sec. Not all device options are released for sale as standard models. See the Ordering Guide for details.
The parts differ in terms of reset output configuration. The ADM8616 is active-low with a push-pull output, while the ADM8617 is active-low with an open-drain output.
The ADM8616/ADM8617 are available in 4-lead SC70 packages and typically consume only 5 μA, making them suitable for use in low power, portable applications.
