This datasheet describes the ADM6315, an open-drain microprocessor supervisory circuit with a manual reset input, available in a 4-lead SOT-143 package.
The ADM6315 is a reliable voltage monitoring device designed to detect power supply degradation as low as 1.8%. It monitors voltages from 2.5 V to 5 V in 100 mV increments and includes a debounced manual reset input (MR) for user intervention. The device is suitable for microprocessor systems, controllers, and safety-critical applications.
| Operating Voltage | 2.5 V to 5.5 V |
|---|---|
| Supply Current (Typical) | 5 μA |
| Reset Voltage Threshold Accuracy | ±1.8% at 25°C |
| Reset Timeout Periods | 1 ms, 20 ms, 140 ms, or 1120 ms |
| Package Type | 4-Lead SOT-143 |
| Operating Temperature Range | -40°C to +125°C |
The device is designed to monitor as little as a 1.8% degradation of a power supply voltage.
The MR pin is a manual reset input that allows the system operator or a digital circuit to reset the system.
Yes, the ADM6315 is pin compatible with the ADM811.
