Analog Devices Inc. ADM1816-R23ARTZ-RL Voltage Supervisor

The ADM1816-R23ARTZ-RL is a highly precise, low-power voltage supervisor designed to monitor power supplies in digital systems. Manufactured by Analog Devices Inc., a leader in high-performance analog, mixed-signal, and digital signal processing integrated circuits, this product ensures system reliability and stability by providing excellent accuracy in monitoring voltage levels.

This voltage supervisor is particularly useful in microprocessor systems, where it can assert a reset signal whenever the VCC supply voltage drops below a predetermined threshold, ensuring the proper operation of the system during power-up, power-down, and brown-out conditions. The reset signal maintains the system in the reset state for a minimum of 140 ms after the supply voltage exceeds the reset threshold, providing ample time for the system to stabilize.

Key Features of the ADM1816-R23ARTZ-RL:

• Voltage Threshold: The device has a preset threshold voltage of 2.3V, which is ideal for monitoring 2.5V power supplies.
• High Accuracy: With a tight monitoring threshold accuracy of ±1.5%, the ADM1816 provides reliable monitoring to prevent system errors.
• Low Power Consumption: The device consumes a low supply current, making it suitable for power-sensitive applications.
• Reset Timeout: Features a minimum reset timeout period of 140ms, ensuring the system has sufficient time to recover after a voltage drop.
• Push-Pull Active Low Reset Output: The reset output is of the push-pull type and is asserted low upon detection of an out-of-tolerance power supply, eliminating the need for external pull-up resistors.
• Small Package: The ADM1816 comes in a small 4-lead SOT-143 package, which is ideal for space-constrained applications.
• Temperature Range: It operates over an industrial temperature range of -40°C to +125°C, suitable for harsh environments.

With its combination of features, the ADM1816-R23ARTZ-RL voltage supervisor from Analog Devices Inc. is an excellent choice for ensuring the reliability and proper functioning of microprocessor systems, portable electronics, and other digital systems that require precise voltage monitoring.
