Overview

The MIC841HYC5-TR is an ultra-low power comparator featuring an internal 1.25V reference and adjustable hysteresis. It operates with a typical supply current of only 1.5 microamps, making it suitable for monitoring tasks in battery-powered systems where power conservation is critical. The push-pull output design eliminates the need for an external pull-up resistor while supporting a wide input range up to 6V.

Why Choose This Part

The component offers extremely low power consumption of 1.5uA typical and 3uA maximum, significantly reducing the power budget for supervisory circuits. It includes external adjustable hysteresis to prevent output chatter in the presence of noisy signals, and is designed to be immune to brief input transients.

Applications

Battery Voltage Monitoring
Ideal for low-battery detection in handheld devices where the 1.25 percent accuracy and low current draw extend operating life.
Threshold Detection
Used in power supply sequencing or window comparators to ensure system rails are within operational limits.
Reset Circuitry
Functions as a simple voltage supervisor to trigger system resets or interrupts when supply levels drop below critical thresholds.
Portable Instrumentation
Small SC-70-5 footprint allows for precision signal level checking in space-constrained sensor nodes.

Getting Started

To implement the MIC841HYC5-TR, designers should calculate the external resistor divider for the HYST pin to set the desired hysteresis level. For prototyping, use an SC-70-5 to DIP adapter board. Ensure a 0.1uF bypass capacitor is placed close to the VDD pin to maintain stability during output switching.
