Overview

The MIC841LYC5-TR is a micro-power comparator featuring an internal 1.25 percent voltage reference and adjustable hysteresis. It operates with a very low supply current of 1.5uA and supports a wide supply voltage range from 1.5V to 5.5V. This device is designed for precision monitoring in space-constrained applications, packaged in a compact 5-pin SC-70.

Why Choose This Part

The 1.5uA typical supply current significantly extends battery life in always-on monitoring circuits. Its adjustable hysteresis allows designers to eliminate output chatter caused by noise or slow-moving input signals without adding external active components. The integrated 1.25 percent reference provides high accuracy for trip points across the -40C to +85C temperature range.

Applications

Precision Battery Monitoring
Used as a low-battery indicator or overvoltage protector in single-cell Li-ion or multi-cell alkaline systems.
Threshold Detection
Ideal for wake-up circuitry where the system must remain in a deep-sleep state until a specific voltage level is reached.
Window Comparators
Can be combined with other units to monitor voltage rails for power-good signaling in portable electronics.

Getting Started

To implement adjustable hysteresis, connect a resistor between the reference output and the hysteresis input pin as specified in the datasheet. Ensure the push-pull output is matched to the logic level of the downstream MCU, keeping in mind the 20mA maximum output current capability. For prototyping, use an SC-70 to DIP adapter board to integrate the component into a breadboard environment.
