MIC842NYMT-TR

Comparators Overview

The MIC842NYMT-TR is a micro-power, precision-voltage comparator manufactured by Microchip Technology. It features an internal voltage reference with ±1.25% accuracy and fixed internal hysteresis of 20 mV. The device operates on a single supply voltage ranging from 1.5 V to 5.5 V with a typical supply current of 1.5 µA. It utilizes an open-drain output stage capable of being pulled up to 6 V regardless of the supply voltage. The component is housed in a 4-pin 1.2 mm x 1.6 mm Thin DFN package.

Comparators Feature Summary

Comparators Procurement Notes

Verify that the ordering suffix matches the required media type and package configuration. Confirm the specific pinout requirements for the 4-pin TDFN footprint during PCB layout. Ensure the design accounts for the open-drain nature of the output stage by including an appropriate external pull-up resistor. Check datasheet specifications for absolute maximum ratings to prevent damage during operation.

Comparators Selection Notes

Select this part when a fixed hysteresis value is acceptable for the application. Choose the open-drain output variant if the system requires pulling the output signal to a voltage level higher than the IC supply voltage. Consider the low supply current requirement for battery-operated devices. Verify that the input voltage range does not exceed the specified limits relative to the supply voltage.

Comparators Part Context

This component belongs to the MIC841/2 family of comparators. It shares the same core architecture as the MIC841 but differs in having fixed internal hysteresis instead of adjustable hysteresis. The 'N' designation indicates the open-drain active-low output configuration. The 'MT' suffix specifies the 4-pin Thin DFN package format.
