TL331KDBVRG4

Comparators Overview

The TL331KDBVRG4 is a single-channel analog comparator manufactured by Texas Instruments, designed for high-voltage, cost-optimized applications. It operates within a supply voltage range of 2V to 36V or ±1V to ±18V. The device features an open-collector, rail-to-rail output and is housed in a compact SOT-23-5 package. Key electrical specifications include a maximum input offset voltage of 5mV at 30V, a typical output current of 20mA, and a maximum quiescent current of 700µA. It supports surface mount installation and functions reliably across an extended temperature range from -40°C to +105°C.

Comparators Feature Summary

• High-voltage operation capability with wide supply voltage range
• Cost-optimized design for general-purpose comparison tasks
• Open-collector output compatible with various logic families
• Compact SOT-23-5 surface-mount packaging

Comparators Applications

• General-purpose voltage monitoring circuits
• Threshold detection systems
• Over-voltage protection schemes
• Signal conditioning interfaces
• Battery management unit comparators

Comparators Procurement Notes

Verify the specific suffix G4 indicates RoHS compliance and green material status as per Texas Instruments documentation. Confirm the SOT-23-5 package marking codes match the latest PCN updates. Ensure the ordering part number aligns with the required tape-and-reel quantity specifications for automated assembly processes.

Comparators Selection Notes

Select this component when a single comparator with high-voltage tolerance is required in a small footprint. The open-collector output necessitates an external pull-up resistor; ensure the chosen resistor value supports the desired switching speed and logic level compatibility. Verify that the 700µA quiescent current meets the system power budget constraints.

Comparators Part Context

This device belongs to the TL331 family of analog comparators from Texas Instruments. It serves as a low-cost alternative to more complex operational amplifiers used in simple threshold detection roles. The KDBVRG4 designation specifies the industrial temperature grade, SOT-23-5 package, and RoHS-compliant reel packaging configuration.

Comparators Replacement Considerations

Consult official Texas Instruments substitution guides for direct pin-compatible alternatives within the TL331 series. Verify that any substitute maintains the same SOT-23-5 footprint and electrical characteristics, particularly the 20mA output drive capability and 5mV max offset voltage.
