MXM1120SO MXM1120SO Digital Hall Sensor Feb, 13, 2015 Ver. 0.1 This document is subject to change without notice Confidential - 1 - Ver 0.1 MXM1120SO 1. Overview MXM1120SO is the digital Hall sensor in measuring the intensity of the magnetic flux through selecting options of the various sensitivity with the low power consumption providing a built-in 10 bits ADC digital output. It can also detect the open/close state for many applications by one or multiple external magnets. This sensor is comprised of a Hall element, an offset cancellation circuitry, a programmable gain amplifier, a 10-bits low power ADC, and control logic in a single chip. The adjustment of the open/close state threshold values, the magnetic polarity, and the operation period can be programmed through I2C interface. The software package supports to convert the magnetic strength into the angle or distance by detecting intensity of flux between the external magnet and the sensing element. Because the small SOP package, the low current consumption, and the stable performance, Our MXM1120SO can be used in the hand set and consumer electronics and any other industries. Functions: Magnetometer device for magnets on external equipment Built-in analog to digital converter for magnetometer data outputs 10/8-bits selectable data outputs for each built-in Hall element I2C bus interface: - Standard mode and fast mode compliant with Philips I2C specification Ver.2.1 Interrupt function: When magnetic intensity level sensed is higher than upper threshold level or lower than lower threshold level, interrupt signal is generated through INTB PAD. Configurable magnetic sensitivity level and measurable range, for example - High sensitivity mode 3.8mT (typically) at 7.5uT/LSB (10bit) - High dynamic range mode 61.2mT (typically) at 120uT/LSB (10bit) Built-in oscillator for internal clock source Power on Reset circuit Operating temperature: -30C to +125C Operating supply voltage: Analog power supply (VDD): +2.7V to +3.6V (3.0V typical) Digital Interface supply (VID): +1.65V to VDD (1.8V typical) Current consumption: Power-down mode: 0.1 A typically Normal operating mode: 18A typically at 10 Hz operating frequency (OPF 2:0 = 001) Package: MXM1120SO 8-pin SOP Package: 4.93 mm 5.99 mm 1.63 mm (typically) Confidential - 2 - Ver 0.1
