Microchip Technology, Inc. Analog Comparators MIC841NYMT-TR

The Precision Comp, Single, 10Us, TDFN-6 (part number 03AJ2221) is a micropower voltage comparator designed for precision voltage monitoring applications. It operates within a supply voltage range of 1.5V to 5.5V and features a low typical supply current of 1.5OºA, making it suitable for battery-powered devices. The comparator offers a propagation delay of 10Oºs and has a voltage threshold accuracy of ¬±1.25%. The device is available in two configurations: the MIC841, which allows for externally adjustable hysteresis, and the MIC842, which includes fixed internal hysteresis. Output options include push-pull configurations (active high or low) and an open-drain output that can be pulled to 6V regardless of the supply voltage. The compact TDFN package dimensions are 1.6mm x 1.6mm for the MIC841 and 1.2mm x 1.6mm for the MIC842, facilitating integration into space-constrained designs. Applications include smartphones, PDAs, precision battery monitoring, and battery chargers, making this comparator a versatile choice for engineers looking for reliable voltage detection solutions.
