The AME8500 / 8501 µµµµµProcessor Supervisory is a low power µP supply monitor that offers a wide range of reset voltage thresholds, reset time intervals, and output driver configuration options to meet a variety of application requirements. The device is available in SOT-23 and SOT-89 small packages and features a wide temperature range of -40oC to 85oC and a low temperature coefficient of 100ppm/oC(max). In addition, the AME8501 includes an overtemperature shutdown function.
The AME8500 family of processor supervisory circuits allows users to customize CPU reset functions without external components. These devices monitor power supply voltages in battery-based systems, asserting a reset immediately if the voltage drops below a preset threshold and releasing it after a specific time interval once the voltage recovers.
| Supply Voltage Range | 1.6-5 V |
|---|---|
| Ambient Temperature Range | -40 to +85 °C |
| Quiescent Current | <3.0uA |
| Thermal Shutdown Threshold (AME8501) | >80°C |
| Package Types | SOT-23, SOT-89, SOT-25 |
When the ambient temperature exceeds 80°C a reset is asserted and remains asserted until the temperature falls below 60°C.
Yes, an external pull-up resistor is required if an open-drain output is used.
