MIC842HYC5-TR

Comparators Overview

The MIC842HYC5-TR is a micro-power analog comparator manufactured by Microchip Technology, featuring an integrated voltage reference and fixed internal hysteresis. It operates within a supply voltage range of 1.5V to 5.5V with a typical supply current of 1.5µA. The device incorporates a push-pull active-low output stage capable of sourcing or sinking up to 20mA. It utilizes a Teeny 5-pin SC-70 package and provides a propagation delay of 10µs. The internal reference voltage is 1.24V with ±1.25% accuracy, and the fixed hysteresis is 20mV.

Comparators Feature Summary

• Integrates a precision bandgap voltage reference with a high-gain comparator for threshold detection applications.
• Features a push-pull output stage configured as active-low, eliminating the need for external pull-up resistors in most configurations.
• Includes internally fixed hysteresis to prevent output oscillation caused by input noise near the switching threshold.
• Designed for low-power operation with extremely low quiescent current suitable for battery-powered portable electronics.

Comparators Applications

• Precision battery monitoring systems
• Battery charger management circuits
• Smartphone power management
• PDAs and handheld devices

Comparators Procurement Notes

Verify the specific suffix 'C5' corresponds to the SC-70-5 package and 'TR' indicates tape-and-reel packaging. Confirm that the 'H' designation matches the required active-low push-pull output configuration. Ensure the operating temperature range aligns with system requirements. Cross-reference the datasheet revision to confirm pinout consistency.

Comparators Selection Notes

Select this component when a fixed hysteresis value is acceptable, distinguishing it from the adjustable hysteresis MIC841 series. Choose the push-pull output variant if driving loads directly without external pull-ups is preferred over open-drain configurations. Consider the 1.5µA supply current for strict power budget constraints in portable designs.

Comparators Part Context

This part belongs to the MIC841/2 family of micro-power comparators. It shares the same core architecture and electrical characteristics as other variants but differs in output stage type (Push-Pull vs Open-Drain) and package footprint (SC-70-5 vs TDFN). The 'MIC842' designation specifically denotes the inclusion of fixed internal hysteresis.

Comparators Replacement Considerations

MIC842LYC5-TR: Identical specifications except for Active-High push-pull output. MIC842NYC5-TR: Identical specifications except for Open-Drain active-low output. MIC841HYC5-TR: Similar package and output, but features externally adjustable hysteresis requiring additional components.
