MultiDimension Technology Co., Ltd. MicroAmpere High Frequency Response Omnipolar Magnetic Switch Sensor TMR13Dx

Description TMR13Dx is an omnipolar magnetic switch integrated the tunnel magnetoresistance (TMR) magnetic sensor and CMOS circuitry, which is able to detect the change of magnetic field and output high and low voltage signals for high accuracy position detection. Compared with traditional TMR switches, TMR13Dx can provide better product performance consistency by pre-programing the switch points (operating point BOP, release point BRP, and hysteresis BH) based on customers’ needs before delivery. Unlike Hall/AMR sensors, TMR sensors with extremely high resistance values allows TMR13Dx to achieve the supply current as low as 1.5 μA while operating in the full-time power supply mode, and maintaining the response frequency of the magnetic signal is greater than 1 kHz. Therefore, TMR13Dx can provide true continuous detection of magnetic field signals, avoiding sampling errors from the traditional time-sharing power supply mode. TMR13Dx allows a wide range of operating supply voltages from 1.8 V to 5.5 V with excellent temperature characteristics, and can meet the requirements of most applications.
