TCM811LERCTR

Supervisors Overview

The TCM811LERCTR is a microprocessor reset monitor manufactured by Microchip Technology, designed to supervise voltage levels in embedded systems. It operates within a supply voltage range of 1.6 V to 5.5 V and features a threshold voltage of 3.08 V. The device provides an active-low push-pull output with a manual reset capability and a fixed reset delay time of 240 ms. It consumes a typical operating current of 6 µA and dissipates up to 320 mW. The component is housed in a SOT-143-4 package suitable for surface mount installation and functions reliably across an industrial temperature range from -40°C to +85°C.

Supervisors Feature Summary

• Provides supervised power-on reset functionality with manual reset input capability
• Features low quiescent current consumption for battery-operated applications
• Delivers active-low push-pull output signal for direct interface with logic circuits

Supervisors Applications

• Microcontroller power supply supervision
• Embedded system voltage monitoring
• Portable electronic device power management

Supervisors Procurement Notes

Verify the exact suffix 'CTR' against the official Microchip datasheet to confirm reel packaging specifications and tape-and-reel dimensions. Ensure the order matches the specific threshold voltage variant required for the target application circuit design.

Supervisors Selection Notes

Select this component when a single-channel voltage supervisor with manual reset is required. Compare the 3.08 V threshold against the minimum operating voltage of the monitored processor. Verify that the SOT-143-4 package fits the available PCB footprint and thermal constraints.

Supervisors Part Context

This part belongs to the MIC811/TCM811 family of 4-pin reset monitors. It shares functional similarities with other devices in the series but differs in specific threshold voltages and package options. The TCM811 variant typically denotes specific manufacturing or packaging distinctions within the broader product line.

Supervisors Replacement Considerations

Check for cross-reference parts such as MIC811TUY-TR which shares similar electrical characteristics and package type. Verify pin compatibility and threshold voltage alignment before substitution.
