The ADM8616/ADM8617 are supervisory circuits that monitor power supply voltage levels and code execution integrity in microprocessor-based systems. A power-on reset signal is generated 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. 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.
