ADM1815-R22AKSZ-R7: A Robust Voltage Supervisor from Analog Devices Inc.

The ADM1815-R22AKSZ-R7 is a precision voltage supervisor designed to monitor power supplies in digital systems, ensuring reliable operation and system integrity. Manufactured by Analog Devices Inc., a leader in high-performance semiconductors, this component is crucial for applications that require consistent and accurate voltage monitoring.

This voltage supervisor is tailored to maintain system stability by providing an active low reset signal whenever the monitored voltage falls below a predefined threshold, known as the reset voltage (V_RST). For the ADM1815-R22AKSZ-R7, this threshold is set at 2.2V, making it suitable for low-voltage operations commonly found in modern digital electronics.

The device comes in a compact, surface-mount SOT-23 package, which is ideal for space-constrained applications. Its small size does not compromise its performance, as it offers a tight reset threshold accuracy of ±1.5%, ensuring precise monitoring and control of the power supply voltage.

Key features of the ADM1815-R22AKSZ-R7 include:

• Reset Threshold Voltage: Precisely set at 2.2V for targeted low-voltage applications.
• Reset Timeout Delay: The reset output remains active for a minimum of 140ms (typical) after the voltage rises above the reset threshold, providing ample time for the system to stabilize.
• Low Power Consumption: With a quiescent current of typically 3.3µA, this device is optimized for power-sensitive applications.
• High Accuracy: Features a reset threshold accuracy of ±1.5%, which is crucial for reliable system operation.
• Temperature Range: Operates over an industrial temperature range of -40°C to +85°C, suitable for harsh environments.
• Supply Voltage Range: Designed to work with a wide supply voltage range, accommodating various application requirements.
