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 micro-processor if it fails to strobe within a preset timeout period. A reset signal can also be asserted by 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.

Each part of ADM6316/ADM6317/ADM6318/ADM6319/ADM6320/ ADM6321/ADM6322 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/ADM6317/ADM6318/ADM6319/ADM6320/ ADM6321/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.
