MIC810MUY-TR

Supervisors Overview

The MIC810MUY-TR is a voltage supervisory circuit manufactured by Microchip Technology, designed to monitor power supply integrity in electronic systems. It operates within a supply voltage range of 1.6 V to 5.5 V and features a fixed threshold voltage of 4.38 V for precise monitoring. The device provides an active-low, push-pull output signal to ensure reliable reset generation. It includes a manual reset input capability, allowing external control over the reset state. The component is housed in a compact SOT-23-3 package, suitable for surface-mount applications. It functions without a watchdog timer or battery backup switch, focusing on core voltage supervision with a reset delay time of 240 ms across an industrial temperature range of -40°C to +85°C.

Supervisors Procurement Notes

Verify the specific suffix 'MUY' corresponds to the 4.38 V threshold and SOT-23-3 package when sourcing. Confirm RoHS compliance status through official Microchip documentation prior to procurement. Ensure the ordering part number matches the exact electrical specifications required for your design, as variations exist within the MIC810 family. Cross-reference datasheet revisions to confirm pinout and functional consistency.

Supervisors Selection Notes

Select this component when a fixed 4.38 V threshold is required for voltage supervision. The manual reset feature makes it suitable for designs needing external reset control. Consider the SOT-23-3 package size for space-constrained PCB layouts. Verify that the 240 ms reset delay aligns with system startup timing requirements. Ensure the operating voltage range covers the minimum and maximum supply voltages of the target application.
