Linear Comparators

MCP6542-I/SN Description

The MCP6542-I/SN from Microchip Technology is a dual general-purpose comparator designed for low-power, precision applications. Packaged in an 8-pin SOIC (Surface Mount) configuration, it operates over a 1.6V to 5.5V supply range, making it ideal for battery-powered and portable devices. With an ultra-low quiescent current of 1µA (max), it minimizes power consumption while delivering robust performance. The comparator features a 6.5mV hysteresis for noise immunity and a 7mV max input offset voltage at 5.5V, ensuring accuracy in signal detection. Its 8µs propagation delay and 1pA input bias current further enhance its suitability for precision applications.

MCP6542-I/SN Features

• Low Power Consumption: 1µA max quiescent current extends battery life in portable applications.
• Wide Voltage Range: Operates from 1.6V to 5.5V, compatible with 1.8V, 3V, and 5V systems.
• High Noise Immunity: 6.5mV hysteresis prevents false triggering in noisy environments.
• Low Input Bias Current: 1pA (max) minimizes loading effects on signal sources.
• Excellent CMRR/PSRR: 70dB CMRR and 80dB PSRR ensure stable performance under varying supply conditions.
• Robust Packaging: RoHS3 compliant and MSL1 (Unlimited) rated for easy handling and reliability.

MCP6542-I/SN Applications

• Battery-Powered Devices: Ideal for wearables, IoT sensors, and medical monitors due to ultra-low power draw.
• Threshold Detection: Used in overvoltage/undervoltage protection circuits and window comparators.
• Signal Conditioning: Enhances sensor interfaces (e.g., temperature, light) with high CMRR and hysteresis.
• Consumer Electronics: Suitable for touch controls, battery management, and low-voltage logic level shifting.
• Industrial Systems: Reliable in motor control, power monitoring, and automation systems due to wide voltage range and noise immunity.

Conclusion of MCP6542-I/SN

The MCP6542-I/SN stands out as a high-efficiency, precision comparator for low-voltage and power-sensitive designs. Its combination of low quiescent current, wide supply range, and robust noise immunity makes it a versatile choice for consumer, industrial, and battery-operated applications. Compared to similar models, its ultra-low input bias current and hysteresis provide superior accuracy, while Microchip’s reliability ensures long-term performance. Whether for threshold detection or signal conditioning, this comparator delivers exceptional value in a compact SOIC package.
