TLI4965-5M Current Sensor

Updated: 2026-07-24

Overview

The TLI4965-5M is a high-performance Hall-effect sensor developed for precision magnetic field detection in demanding environments. As part of the growing family of industrial sensors, it combines reliability with advanced sensing technology. This component is particularly valued in automotive and industrial automation sectors where accurate position or speed measurements are critical. Its compact design allows for easy integration into various systems while maintaining high performance standards.

Structure and Working Principle

The TLI4965-5M consists of a Hall-effect element, signal conditioning circuitry, and output driver housed in a robust package. The core technology leverages the Hall effect - when a magnetic field is applied perpendicular to current flow in a conductor, it generates a voltage difference. This sensor utilizes a bipolar technology that responds to both north and south magnetic poles. The integrated circuitry provides temperature compensation and signal processing, delivering a clean, amplified output signal that's proportional to the magnetic field strength.

Key Features

Among its standout features is the exceptionally low power consumption, typically in the range of 2-5mA, making it suitable for battery-powered applications. The sensor operates across a wide temperature range (-40°C to 150°C), ensuring reliability in harsh environments. The device offers high sensitivity with typical magnetic switching points at ±5mT, providing precise detection capabilities. Its fast response time (typically <5μs) enables accurate measurement of rapidly changing magnetic fields, crucial for speed sensing applications.

Application Areas

Automotive systems represent the primary application area, where the TLI4965-5M is used for throttle position sensing, gearbox speed detection, and brake pedal position monitoring. Its robust design meets automotive quality standards. In industrial settings, the sensor finds use in motor control systems, flow meters, and linear position detection. The medical equipment sector employs it in devices requiring precise motion control, benefiting from its reliability and accuracy.

Maintenance and Precautions

Proper installation is crucial for optimal performance. Maintain recommended clearance between the sensor and magnetic target, typically 0.5-3mm depending on magnet strength. Avoid mechanical stress during mounting that could damage the package. For long-term reliability, ensure the operating environment stays within specified temperature and humidity ranges. While the sensor is protected against reverse polarity and overvoltage, proper circuit protection is still recommended in the system design.

B2B Procurement Guide

When sourcing the TLI4965-5M, verify the manufacturer's certification and quality control processes, as counterfeit components can be an issue in the semiconductor market. Consider ordering from authorized distributors to guarantee authenticity. For bulk purchases (typically 1,000+ units), negotiate pricing based on volume. Lead times can vary from 4-12 weeks depending on market demand, so plan procurement accordingly. Evaluate whether tape-and-reel packaging is required for automated assembly processes.
