MIC74BQS-TR

I/o Expanders Overview

The MIC74BQS-TR is a supervisory circuit manufactured by Microchip Technology, designed to monitor system voltage levels. It operates within a supply voltage range of 2.0 V to 5.5 V and features a push-pull active-low output. The device provides a reset delay time of 140 ms to ensure stable power-up conditions. It is housed in a compact 8-pin QSOP package and supports an operating temperature range from -40°C to +85°C.

I/o Expanders Feature Summary

• Monitors supply voltage with a fixed threshold for reliable system supervision
• Provides an active-low push-pull reset output for direct logic interfacing
• Includes a programmable reset delay to prevent false triggers during power transitions

I/o Expanders Applications

• Portable battery-powered equipment requiring voltage monitoring
• Embedded systems needing power-on reset generation
• Industrial control units utilizing microcontroller supervision

I/o Expanders Procurement Notes

Verify the specific suffix 'TR' indicates tape-and-reel packaging when ordering. Confirm the active-low output polarity matches the target design requirements. Ensure the 8-pin QSOP footprint aligns with the PCB layout. Check RoHS compliance status through official Microchip documentation prior to final procurement decisions.

I/o Expanders Selection Notes

Select this component when a fixed voltage threshold and active-low output are required. The 140 ms reset delay suits applications with moderate power-up ramp times. Consider the 8-pin QSOP package constraints for space-limited designs. Verify input voltage compatibility with the 2.0 V to 5.5 V operational range before integration.

I/o Expanders Part Context

This part belongs to the MIC74 supervisory circuit family, which offers various threshold voltages and output polarities. The MIC74 series is engineered for cost-sensitive applications requiring basic power management functions. It complements Microchip's broader portfolio of power management integrated circuits.

I/o Expanders Replacement Considerations

Consult Microchip datasheets for alternative parts within the MIC74 series offering different thresholds or output polarities. Cross-reference with other supervisory IC families only if pinout and electrical specifications match exactly.
