Digial Hall Sensor

The MXM1120 is a multi-function Hall-effect sensor designed with mixed signal CMOS technology. The device integrates Hall elements, dynamic offset cancellation system, a programmable amplifier, low power ADC and an arithmetic logics in a single chip. Bop, Brp, operation magnetic polarity and operation period are programmable by I2C interface.

On-the-shelf s/w package is able to transform each magnetic strength into angle between the magnet and the device with robust algorithm. Small WLCSP footprint and low power operation enables to implement angle gaging system in mobile handset and industrial system.

Hall Switch

The MXM1170 is an integrated Hall effect magnetic switch with dynamic offset cancellation, low power consumption, and temperature stability of the magnetic thresholds for highly accurate applications. This sensor is comprised of a Hall element, an offset cancellation circuitry, a low noise gain amplifier, a comparator, and control logic in a single chip.

The MXM1170 supports for programmable function via single wired interface in order to provide more flexible design by changing operation mode (omni-polar/bi-polar/uni-polar), operation threshold level, and output port type. The MXM1170 has very thin DFN package and is suitable for mobile phones, consumer electronics and industry applications
