The MIC841LYC5-TR is a ultra-low-power, single-supply comparator from Microchip’s Teeny™ series, designed for compact, high-efficiency signal detection in battery-operated and space-constrained systems. This surface-mount SC-70-5 package device operates with a supply voltage range of 1.5V to 5.5V and features an integrated 1.22V voltage reference. It delivers a push-pull output with a maximum output current of 20mA, enabling robust signal switching. The comparator’s 20mV hysteresis minimizes noise sensitivity, while its 12µs maximum propagation delay ensures fast response times. Ideal for low-power applications, it combines a quiescent current as low as 3µA with a shutdown mode for further power savings.

Key Features

This comparator offers a wide single-supply operating range (1.5V–5.5V) and integrates a precision 1.22V reference for accurate threshold detection. Its 20mV hysteresis reduces false triggering in noisy environments, while the push-pull output supports direct drive of digital loads. The device operates across an industrial temperature range (-40°C to +85°C) and features a 1MHz bandwidth for high-speed applications. With a typical propagation delay of 12µs, it balances speed and power efficiency. The SC-70-5 package (2.2mm × 1.8mm) enables ultra-compact PCB integration, making it suitable for miniaturized designs.

Applications

Primarily used in battery-powered devices (e.g., wearables, IoT sensors, and portable instruments), the MIC841LYC5-TR excels in low-power monitoring systems requiring precise voltage threshold detection. Its small footprint and low quiescent current make it ideal for medical devices, industrial sensors, and automotive electronics. It is also employed in power management circuits, overvoltage/undervoltage protection, and signal conditioning in consumer and industrial control systems.

Summary

The MIC841LYC5-TR combines ultra-low power consumption, integrated voltage reference, and compact form factor, positioning it as a versatile solution for analog signal comparison in resource-constrained environments. Its robust noise immunity, fast response, and wide operating voltage range make it a key component for battery-operated, portable, and high-reliability applications across multiple industries. This device remains a reliable choice for designers seeking minimal footprint and energy-efficient performance.
