Overview

The TCS40DPR,LF is an omnipolar Hall effect switch designed for robust magnetic sensing applications. It features a push-pull output and can detect both North and South magnetic poles. This sensor operates from a supply voltage of 2.3V to 5.5V and has a low quiescent current.

Why Choose This Part

This Hall effect switch offers omnipolar detection, simplifying magnet orientation during assembly and reducing design complexity. Its push-pull output provides clear high and low states, compatible with most microcontroller inputs. The low operating current of 1.6mA (at 5.0V) and a sleep current of 19uA makes it suitable for power-sensitive applications.

Applications

Industrial Position Sensing
Used for non-contact detection of mechanical movement and position in industrial machinery and automation systems, where both pole detections are beneficial.
Security System Proximity Detection
Ideal for sensing the opening and closing of doors, windows, or covers in security systems, leveraging its omnipolar detection for flexibility in magnet orientation.
White Goods Appliance Control
Suitable for detecting lid closure, door status, or rotary encoder positions in home appliances like washing machines or refrigerators, contributing to user interface and safety features.
Flow Metering
Can be integrated into flow meters to detect the rotation of a magnetic impeller, providing pulses for flow rate calculation due to its reliable magnetic switching.
IoT and Smart Devices
Its low 19 uA sleep current and small SOT-23F package make it suitable for battery-powered IoT devices requiring compact and efficient magnetic sensing.

Getting Started

To get started with the TCS40DPR,LF, integrate it into a breadboard or custom PCB using its SOT-23F footprint. Connect VDD to a 2.3V to 5.5V supply, GND to ground, and the OUT pin to a microcontroller's GPIO. Observe the output state change by bringing a magnet (either North or South pole) within +/-4.4mT trip and +/-0.9mT release ranges.
