Product Overview: ADM1817-20ARTZ-RL7

The ADM1817-20ARTZ-RL7 is a high-precision supervisory circuit manufactured by Analog Devices Inc., a company renowned for its innovative and reliable semiconductor products. This microprocessor supervisory circuit is designed to monitor power supplies in digital systems, ensuring that the system remains within operational voltage limits and providing a reset signal to the host processor when necessary.

Key Features

• Voltage Monitoring: The device keeps a vigilant eye on the supply voltage, triggering a reset when the monitored voltage drops below the factory-set threshold of 2.0V. This feature is crucial for preventing microprocessor malfunction due to low voltage conditions.
• Reset Timeout: Upon detection of an out-of-tolerance condition, the ADM1817-20ARTZ-RL7 asserts a reset signal that remains active for a minimum of 140ms after the supply voltage has risen above the reset threshold, ensuring system stability during power-up.
• Low Power Consumption: With a quiescent current of typically 17μA, this device is an excellent choice for power-sensitive applications.
• High Accuracy: The reset threshold accuracy is ±1.5%, providing a reliable reset activation point.
• Package: Available in a compact SOT-23 package, the ADM1817-20ARTZ-RL7 is suitable for space-constrained applications.
• Temperature Range: It operates over the industrial temperature range of -40°C to +125°C, accommodating a wide range of environmental conditions.
