Technical data sheet for Analog Devices supervisory circuits featuring watchdog timers, manual reset inputs, and multiple output stage configurations in…
The ADM6316 through ADM6322 are supervisory circuits designed to monitor power supply voltage levels and code execution integrity in microprocessor-based systems. These devices provide power-on reset signals and include an on-chip watchdog timer that can reset the microprocessor if it fails to strobe within a preset timeout period. A manual reset input allows external assertion of the reset signal via a push button.
| Supply Current (VCC = 5.5 V) | 10 µA typical, 20 µA max |
|---|---|
| Operating Voltage Range | 2.5 V to 5.5 V |
| Reset Threshold Temperature Coefficient | 40 ppm/°C |
| Operating Temperature Range | -40°C to +85°C |
| Package Type | 5-lead SOT-23 |
The devices feature four reset timeout options: 1 ms, 20 ms, 140 ms, and 1120 ms (minimum).
The available watchdog timeout options are 6.3 ms, 102 ms, 1600 ms, and 25.6 sec (typical).
The ADM6318 features a RESET output at pin 1, GND at pin 2, VCC at pin 4, and WDI at pin 5.
