ADM812LART-REEL7

Supervisors Overview

The ADM812LART-REEL7 is a voltage supervisory circuit manufactured by Analog Devices Inc., designed for monitoring single power supply rails. It operates within a supply voltage range of up to 5.5 V and features a push-pull output type with manual reset capability. The device provides specific threshold voltages including 2.5 V, 3 V, 3.3 V, and 5 V, with an overvoltage threshold of 4.72 V. It incorporates a fixed reset delay time of 560 ms and draws a typical operating supply current of 15 uA. The component is housed in an SOT-143-4 package and supports surface mount installation.

Supervisors Procurement Notes

Verify the exact threshold voltage variant required (2.5 V, 3 V, 3.3 V, or 5 V) as these are distinct part numbers within the ADM812 series. Confirm the package type is SOT-143-4 and check RoHS compliance status, as documentation indicates potential non-compliance for this specific reel configuration. Ensure the manual reset feature aligns with system design requirements before procurement.

Supervisors Selection Notes

Select this component when a simple supervisory circuit with manual reset control is needed for low-power applications. The 15 uA supply current makes it suitable for battery-operated devices. Verify that the 560 ms reset delay meets the timing requirements of the monitored microprocessor or logic circuit. Ensure the input voltage does not exceed the 5.5 V maximum rating.

Supervisors Part Context

The ADM812 belongs to the Analog Devices ADM8xx family of voltage supervisory circuits. This family focuses on providing reliable reset signals for digital systems with minimal external components. The ADM812 specifically distinguishes itself by offering manual reset functionality alongside standard power-on reset capabilities, catering to designs requiring user-initiated system resets.
