Digital Hall Sensor

Digital Hall sensor 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

MXM1xxx products are integrated Hall effect magnetic switches 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.

It 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.
