Texas Instruments TMAG5134 In-Plane Hall-Effect Switches

Texas Instruments TMAG5134 In-Plane Hall-Effect Switches are high-sensitivity, low-power digital switches designed to replace TMR, AMR, and reed switches. These switches feature an integrated magnetic concentrator, enabling higher sensitivity and lower power consumption compared to traditional Hall-effect devices. The TMAG5134 switches offer an integrated magnetic concentrator, an in-plane axis of sensitivity, and operate at a 1.65V to 5.5V power supply voltage range. These switches provide omnipolar and dual-unipolar magnetic pole detection options. Typical applications include door and window sensors, appliances, water meters, gas meters, e-locks, medical devices, tablets, laptops, and the Internet of Things (IoTs).

The TMAG5134 switches support multiple combinations of high-sensitivity thresholds with various sampling rates for a flexible system design that accommodates magnet selection, sensitivity, and power requirements. These devices feature a push-pull (CMOS) and open-drain output type, which eliminates the need for an external pull-up resistor, and are available in industry-standard SOT-23 and X1LGA packages.
