The ADM809SART-REEL7 is a microprocessor supervisory circuit from Analog Devices, designed to monitor power supply voltages in electronic systems. It provides a reset output during power-up, power-down, and brownout conditions. Upon power-up, an internal timer holds the reset signal asserted for a minimum of 140 ms, ensuring the microprocessor remains in a stable reset state until power conditions stabilize.
This device features a low power consumption of only 17 μA, making it suitable for battery-powered and portable equipment. The reset output is active low and utilizes a push-pull configuration. It can maintain reset assertion even when VCC drops as low as 1V. The ADM809SART-REEL7 is available in a compact SOT-23-3 package, suitable for surface mount applications.
Key specifications include a monitoring voltage of 2.93V and an operating temperature range of -40°C to 125°C. The circuit is designed with built-in glitch immunity to prevent false resets from fast transients on the VCC line. This makes it a reliable choice for applications requiring stable power monitoring.
