MCHPMIC833YM5-TR
Overview
The MIC833YM5-TR is an ultra-low power comparator with an integrated voltage reference and open-drain output, drawing only 1 microamp of typical supply current. It features independently adjustable high and low threshold inputs, allowing engineers to implement precise hysteresis for window detection or battery monitoring without complex external logic. The device operates across a 1.5V to 5.5V supply range and is housed in a compact 5-pin SOT-23 package.
Why Choose This Part
The primary advantage is the extremely low 1uA quiescent current, which significantly extends battery life in portable devices. It offers 1.5 percent accuracy and is designed to be immune to brief input transients, preventing false triggers in noisy environments. The open-drain output allows for easy level shifting and can drive loads up to 20mA.
Applications
Getting Started
To implement this part, calculate external resistor dividers for the high and low threshold pins to set your desired hysteresis levels. Ensure the open-drain output is pulled up to a logic rail (up to 6V) appropriate for your downstream controller. Prototype using a SOT-23-5 breakout board if using a standard 0.1-inch breadboard.
