Linear Comparators

LM2901PWRG4 Description

The LM2901PWRG4 from Texas Instruments is a quad differential comparator designed for general-purpose applications. Packaged in a 14-pin TSSOP and available in Tape & Reel (TR), it is optimized for surface-mount technology (SMT). This device operates over a wide supply voltage range (2V to 30V single supply, ±1V to ±15V dual supply), making it versatile for various circuit designs. With a low input bias current (max 0.25µA @ 5V) and moderate quiescent current (max 2.5mA), it balances power efficiency and performance. The input offset voltage (max 7mV @ 30V) ensures reliable precision in comparison tasks.

LM2901PWRG4 Features

• Quad Comparator Configuration: Four independent comparators in a single package, reducing board space and cost.
• Wide Voltage Range: Supports 2V–30V (single supply) or ±1V–±15V (dual supply), ideal for mixed-voltage systems.
• Low Power Consumption: Quiescent current ≤2.5mA and output current up to 20mA, suitable for battery-operated devices.
• High Stability: Low input bias current (0.25µA max) and low offset voltage (7mV max) enhance accuracy.
• Robust Packaging: 14-TSSOP with MSL1 (Unlimited) moisture sensitivity, ensuring reliability in storage and assembly.
• Compliance: ROHS3 and REACH compliant, meeting environmental and safety standards.

LM2901PWRG4 Applications

• Voltage Monitoring: Used in power supply supervision, over/under-voltage detection, and battery management systems.
• Signal Conditioning: Ideal for window comparators, zero-crossing detectors, and ADC driver circuits.
• Industrial Control: Deployed in motor control, threshold sensing, and automotive electronics due to its rugged design.
• Consumer Electronics: Found in appliances, portable devices, and audio equipment for low-power signal processing.
• Automotive Systems: Suitable for ECUs (Engine Control Units) and safety-critical monitoring due to its wide temperature tolerance.
