ADM811LART-REEL

Supervisors Overview

The ADM811LART-REEL is a voltage supervisory circuit manufactured by Analog Devices Inc., designed as a microprocessor reset generator. It operates within a supply voltage range up to 5.5 V and features a push-pull output type with manual reset capability. The device monitors a single input and provides a reset delay time of 560 ms. It is available in an SOT-143-4 surface-mount package and supports threshold voltages of 2.5 V, 3 V, 3.3 V, and 5 V. The component functions reliably across an operating temperature range from -40°C to +85°C.

Supervisors Feature Summary

• Provides manual reset functionality for system control
• Features push-pull output configuration
• Monitors a single voltage input channel

Supervisors Applications

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

Supervisors Procurement Notes

Verify availability status carefully, as this part may be subject to limited supply or discontinuation. Confirm the specific threshold voltage variant required, as the base model number covers multiple options. Ensure the SOT-143-4 package compatibility with your PCB design. Check RoHS compliance details if environmental regulations apply to your manufacturing process. Validate that the 5.5 V maximum supply voltage meets your system requirements.

Supervisors Selection Notes

Select this component when a simple voltage supervisor with manual reset is needed. Consider the available threshold voltages (2.5 V, 3 V, 3.3 V, 5 V) to match your rail. The push-pull output allows direct driving of logic inputs. Ensure the 560 ms reset delay is acceptable for your startup sequence. Verify the SOT-143-4 footprint fits your assembly constraints.

Supervisors Part Context

This part belongs to the ADM811 series of voltage supervisors from Analog Devices. It is distinct from other variants like the ADM811TARTZ or ADM811SARTZ which may have different threshold voltages or output types. The REEL suffix indicates tape and reel packaging. It is a dedicated reset generator without watchdog timer functionality.

Supervisors Replacement Considerations

Check for exact threshold voltage matches among ADM811 variants. Compare output types (push-pull vs active low) for compatibility. Verify package pinout similarity for potential board-level swaps.
