MultiDimension Technology Co., Ltd. Microampere High Frequency Response Bipolar Latching Magnetic Switch Sensor TMR1202HT

Description TMR1202HT is a bipolar latching 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. Unlike Hall/AMR sensors, TMR sensors with extremely high resistance values allows TMR1202HT 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 up to 5 kHz. Therefore, TMR1202HT can provide true continuous detection of magnetic field signals, avoiding sampling errors from the traditional time-sharing power supply mode. TMR1202HT 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.
