Overview

The TCS40DLR is an omnipolar Hall effect switch designed to detect both North and South magnetic poles. It features an open-drain output and operates across a supply voltage range of 2.3V to 5.5V. Its low current consumption and SOT-23F package make it suitable for space-constrained, battery-powered sensing applications.

Why Choose This Part

The omnipolar nature simplifies assembly by allowing the sensor to trigger regardless of the magnet's polarity. It features extremely low current consumption, typically 0.5uA quiescent current, making it ideal for always-on battery applications. The open-drain output allows for easy level shifting and interfacing with various microcontroller logic levels.

Applications

Lid and Cover Detection
Used in laptops and handheld devices to detect the opening or closing of a lid using a small magnet.
Non-Contact Limit Switches
Reliable position sensing in industrial machinery where mechanical wear must be avoided.
Smart Home Door/Window Sensors
Triggers security alerts or lighting when a magnetic contact is broken on a door or window frame.
Water and Gas Metering
Counts rotations of internal impellers to measure flow rates without breaching the sealed enclosure.

Getting Started

To integrate the TCS40DLR, connect a 10k ohm pull-up resistor from the output pin to your microcontroller's VCC. Ensure the sensor is placed within the 4.4mT trip range of your chosen magnet for reliable switching. Decouple the supply pin with a 0.1uF ceramic capacitor placed as close to the device as possible to maintain signal integrity.
