MIC8114TU TR

Supervisors Overview

The MIC8114TU-TR is a voltage supervisory circuit manufactured by Microchip Technology, designed to monitor system power integrity. It operates within a supply voltage range of 1.6 V to 5.5 V and features a fixed threshold voltage of 3.08 V for the monitored input. The device provides an active-low, push-pull output and includes a manual reset function. Key timing parameters include a reset delay time of 240 ms. It consumes a typical operating supply current of 6 µA and dissipates up to 320 mW. The component is housed in a SOT-143-4 package and supports surface-mount installation. It functions without a watchdog timer or battery backup switch and is rated for operation between -40°C and +85°C.

Supervisors Feature Summary

• Provides manual reset capability alongside automatic voltage supervision
• Features an active-low push-pull output stage for direct logic interfacing
• Operates with ultra-low quiescent current consumption suitable for battery-powered systems

Supervisors Applications

• Microprocessor reset circuits requiring manual intervention
• Battery-operated electronic devices needing low standby current
• Portable equipment utilizing single-supply voltage monitoring

Supervisors Procurement Notes

Verify the exact part number suffix against official Microchip documentation to ensure correct package and temperature grade specifications. Confirm that the ordering information matches the required threshold voltage and output configuration. Cross-reference datasheet revisions to validate electrical characteristics and pinout assignments before finalizing procurement orders.

Supervisors Selection Notes

Select this component when a fixed 3.08 V threshold is required for systems operating between 1.6 V and 5.5 V. The inclusion of a manual reset button interface distinguishes it from standard supervisor ICs. Consider the 240 ms delay and 6 µA current draw for applications prioritizing low power consumption over fast response times. Ensure the SOT-143-4 package fits the available PCB real estate.

Supervisors Part Context

This device belongs to the MIC811 series of supervisory circuits from Microchip Technology. The series focuses on providing reliable power management solutions for embedded systems. The specific model utilizes a compact surface-mount package to facilitate integration into space-constrained designs while maintaining robust performance across industrial temperature ranges.

Supervisors Replacement Considerations

Consult official Microchip documentation for verified cross-reference part numbers. Do not assume functional equivalence with other voltage supervisors without verifying threshold voltages, output types, and package dimensions against the original specification sheet.
