LM293QT

LM293QT Description

The LM293QT from STMicroelectronics is a dual general-purpose comparator designed for surface-mount applications, packaged in an 8-pin UFSON (Ultra-Thin Fine-Pitch Small Outline No-Lead) format with Tape & Reel (TR) for automated assembly. Operating over a wide supply voltage range (2V to 36V single-supply or ±1V to ±18V dual-supply), it is optimized for low-power consumption, with a quiescent current of just 2.5mA (max). This device is RoHS3 compliant, REACH unaffected, and rated MSL 1 (Unlimited), ensuring reliability in harsh environments.

LM293QT Features

• Dual Comparator Design: Two independent comparators in a single package, reducing board space and cost.
• Wide Voltage Range: Supports 2V–36V (single-supply) or ±1V–±18V (dual-supply), making it versatile for diverse power configurations.
• Low Power Consumption: 2.5mA max quiescent current enhances efficiency in battery-operated systems.
• Robust Packaging: 8-pin UFSON with Tape & Reel for high-volume manufacturing.
• High Reliability: MSL 1 (Unlimited) moisture sensitivity and RoHS3 compliance ensure durability in industrial applications.
• General-Purpose Use: Ideal for analog signal conditioning, threshold detection, and voltage monitoring.

LM293QT Applications

• Battery-Powered Systems: Low quiescent current makes it suitable for portable electronics and IoT devices.
• Automotive Electronics: Wide voltage range supports 12V/24V automotive power systems for functions like overvoltage protection.
• Industrial Control: Used in motor control, level sensing, and window comparators due to its robustness.
• Consumer Electronics: Power management, signal conditioning in audio/video equipment.
• Embedded Systems: Microcontroller interfacing for analog-to-digital threshold detection.

Conclusion of LM293QT

The LM293QT stands out as a highly versatile, low-power dual comparator with broad voltage compatibility and industrial-grade reliability. Its compact UFSON package and efficient performance make it ideal for space-constrained, power-sensitive designs across automotive, industrial, and consumer applications. Compared to similar models, its combination of low power, wide voltage range, and dual-channel integration provides a cost-effective solution for modern electronic systems.
