MIC809TYC3-TR

Supervisors Overview

The MIC809TYC3-TR is a supervisory circuit manufactured by Microchip Technology, designed for monitoring single voltage inputs. It features an active-low push-pull output and operates within a supply voltage range up to 5.5 V. The device provides a reset delay time of 240 ms and has a threshold voltage of 3.08 V. It is housed in an SC70-3 package and supports surface mount installation. The component functions across a temperature range from -40°C to +85°C.

Supervisors Feature Summary

• Provides active-low push-pull output for microprocessor reset applications
• Monitors a single voltage input with a fixed threshold
• Includes a defined reset delay timer for stable power-up sequencing

Supervisors Applications

• Microprocessor reset circuits
• Voltage supervision in embedded systems
• Power management ICs requiring simple supervisor functionality

Supervisors Procurement Notes

Verify the specific suffix 'TYC3' to confirm the 3.08V threshold and SC70-3 package variant. Ensure compatibility with the target PCB footprint for the SC70-3 package. Confirm that the active-low output logic aligns with the connected processor's reset pin requirements. Check RoHS compliance status if required by project specifications.

Supervisors Selection Notes

Select this component when a fixed 3.08V threshold is required for voltage monitoring. The SC70-3 package is suitable for space-constrained designs. The push-pull output allows direct driving of reset lines without additional pull-up resistors. Consider the 240ms reset delay for system startup timing requirements.

Supervisors Part Context

This part belongs to the MIC809 series of supervisory circuits from Microchip Technology. The series includes variants with different threshold voltages and packages. The MIC809 family is designed for low-cost, high-reliability voltage monitoring in industrial and consumer electronics applications.

Supervisors Replacement Considerations

MIC809MYC3-TR offers a 4.38V threshold in the same SC70-3 package. MIC809TUY-TR provides similar functionality but in a SOT-23-3 package with a 140ms reset delay. Verify electrical parameters before substitution.
