Overview

The MIC842HYC5-TR is an ultra-low power micro-power comparator featuring an integrated 1.24V voltage reference and internal 20mV hysteresis. It operates on a supply current of just 1.5uA typical and functions across a wide supply range of 1.5V to 5.5V. This specific variant features a push-pull active-low output stage, eliminating the need for an external pull-up resistor.

Why Choose This Part

The integrated 1.25% accurate reference reduces component count and PCB area compared to discrete solutions. Its 1.5uA supply current makes it one of the most efficient choices for always-on monitoring. Additionally, the internal 20mV hysteresis prevents output chatter in the presence of noise or slow-moving input signals.

Applications

Battery Voltage Monitoring
Ideal for low-battery detection in single-cell Li-Ion or multi-cell alkaline systems where minimal current draw is critical for shelf life.
Threshold Detection
Used in power-on reset or system wake-up circuits to monitor supply rails and trigger events when a specific voltage level is reached.
Portable Electronics
Suits handheld devices and wearables where the small SC-70-5 footprint and 1.5uA current consumption maximize battery endurance.
Window Comparators
Can be paired with an additional MIC841/MIC842 to create over/under-voltage protection circuits for sensitive analog front-ends.

Getting Started

To implement a basic battery monitor, connect the battery to a resistive divider at the input pin to scale the target trip voltage to the internal 1.24V threshold. Ensure decoupling capacitors are placed close to the VDD pin of the SC-70 package to maintain stability during output transitions. Evaluation can be performed by soldering the part to a standard SC-70-5 SMT breakout board for breadboard prototyping.
