ADM812SART-REEL

Supervisors Overview

The ADM812SART-REEL is a voltage supervisory circuit manufactured by Analog Devices Inc., packaged in an SOT-143-4 surface-mount format. It features a push-pull output and supports manual reset functionality without a watchdog timer or battery backup switch. The device monitors a single input with threshold voltages of 2.5 V, 3 V, 3.3 V, or 5 V. It operates within a supply voltage range up to 5.5 V and maintains a quiescent current of 15 uA. The reset delay time is specified at 560 ms, and the component functions reliably across a temperature range from -40 C to +85 C.

Supervisors Feature Summary

• Provides manual reset capability for system control
• Features push-pull output configuration
• Supports multiple fixed threshold voltage options

Supervisors Applications

• Voltage supervision in embedded systems
• Microprocessor reset generation
• Power management monitoring circuits

Supervisors Procurement Notes

Verify component authenticity through authorized channels due to end-of-life status. Confirm RoHS compliance details as documentation indicates non-compliance. Ensure compatibility with existing PCB footprints and thermal requirements before integration. Check for alternative sources if immediate availability is required.

Supervisors Selection Notes

Select this component when manual reset functionality is required alongside standard voltage supervision. Consider the specific threshold voltage variant needed for the target application. Evaluate the SOT-143-4 package constraints against available board space. Assess the 15 uA quiescent current against power budget requirements.
