Haechitech MXM2120 Digital 3-Dimensional Hall Sensor and EVK1000 Evaluation Board

Haechitech’s MXM2120 digital 3-dimensional Hall sensor comes housed in a minute WLCSP-6 package (1.3 mm x 0.8 mm x 0.5 mm) and includes an integrated temperature sensor. With programmable sensitivity, resolution, and various operating functions, the MXM2120 detects magnetic field strength with 14- and 10-bit digital output on the Z and X/Y axes respectively at a rate of 5 Hz to 1 kHz. The MXM2120 also provides user-selectable interrupt conditions and a smart low-power mode that automatically reduces power consumption (current 1 μA in power down mode, 10 μA in 5 Hz operation). The device has an operating temperature of -40°C to +125°C and a measurement range of ±2 mT to ±100 mT, making it suitable for a wide variety of applications.

In general, Haechitech’s digital Hall sensors are multi-functional digital output magnetic sensors designed with mixed signal CMOS technology, and they each have integrated Hall elements, a dynamic offset cancellation system, a programmable amplifier, a low power ADC, and arithmetic algorithm logics in a single chip. Bop, Brp, operation mode, and output data rate are programmable by I3C or I2C interface, and an on-the-shelf software suite transforms magnetic strength measurements to distance or angle between the magnet and the sensor with ease.

The EVK1000 evaluation board allows a user to easily access data from any of Haechitech’s sensor devices. It also allows the use of several different sensor combinations for simultaneous measurement, should you decide that Haechitech sensing infrastructure serves all aspects of your application. The evaluation environment consists of the evaluation software for the user interface and the EVK board. In this configuration, the board is powered by the PC via the provided USB cable, and no other cables are required.
