ADM811TART-REEL

Supervisors Overview

The ADM811TART-REEL is a voltage supervisory circuit manufactured by Analog Devices Inc., designed for monitoring single-input power supplies. It operates within a maximum supply voltage of 5.5 V and features an active low output type with manual reset capability. The device utilizes a SOT-143-4 surface-mount package and provides a fixed reset delay time of 560 ms. It supports threshold voltages including 2.5 V, 3 V, 3.3 V, and 5 V, ensuring precise supervision across standard power levels.

Supervisors Feature Summary

• Provides reliable voltage monitoring with precision thresholds for standard power supply levels
• Includes built-in manual reset input to allow user-initiated system recovery
• Features low power consumption suitable for battery-operated or energy-efficient designs

Supervisors Applications

• Microprocessor systems requiring stable power supervision
• Controllers needing automated reset upon voltage degradation
• Automotive safety systems demanding reliable voltage monitoring
• Portable instruments with limited power budgets

Supervisors Procurement Notes

Verify the specific threshold voltage variant required, as the ADM811 series offers multiple options (2.5 V, 3 V, 3.3 V, 5 V). Confirm that the active low output aligns with the target logic interface. Ensure the SOT-143-4 package footprint matches the PCB design. Check current availability status as distribution may be restricted.

Supervisors Selection Notes

Select this component when a single-channel voltage supervisor with manual reset is needed. Compare against ADM811 variants with different threshold codes to match the specific rail voltage. Consider the 560 ms reset delay duration relative to system startup requirements. Verify compatibility with the operating temperature range of -40 C to +85 C.

Supervisors Part Context

This part belongs to the ADM811 family of microprocessor supervisory circuits from Analog Devices. It serves as a successor to older MAX811/MAX812 devices, offering improved performance over temperature. The series is engineered for applications requiring dependable reset generation under varying supply conditions.

Supervisors Replacement Considerations

Direct substitutes include other ADM811 variants with matching threshold voltages and output polarities. Cross-reference with MAX811 equivalents if legacy compatibility is required, ensuring pinout and electrical specifications align.
