TMR1383S

Datasheet V1.1 TMR1383 High-Voltage TMR Omnipolar Switch General Description TMR1383 is a digital omnipolar magnetic switch that integrates TMR and CMOS technology in order to provide a magnetically triggered digital switch with high sensitivity, high speed, and low power consumption. It is designed for use in applications that are both power-critical and performance-demanding. It contains a push-pull TMR sensor bridge and CMOS signal processing circuitry within the same package, including an on-chip TMR voltage generator for precise magnetic sensing, a TMR voltage amplifier and comparator plus a Schmitt trigger to provide switching hysteresis for noise rejection, and an open-drain output. An internal band gap regulator is used to provide a temperature compensated supply voltage for internal circuits, permitting a wide range of supply voltages from 3V up to 40V. The TMR1383 draws only 0.6mA resulting in low-power operation. It has fast response, accurate switching points, excellent thermal stability, and immunity to stray field interference. It is available in an SOT23-3 package (P/N TMR1383S).

Sensing Direction of Magnetic Field Magnetic Flux Application Information The output of the TMR1383 switches low (turns on) when a magnetic field parallel to the TMR sensor exceeds the operate point threshold |BOPS| or |BOPN|. When the magnetic field is reduced below the release point |BRPS| or |BRPN|, the device output goes high (turns off). The difference between the magnetic operate point and release point is the hysteresis BH of the device. It is strongly recommended that an external bypass capacitor be connected in close proximity to the device between the supply and ground to reduce noise. The typical value of the external capacitor is 0.1μF. 3/5 Datasheet V1.1 Package Information SOT23-3 package drawing TMR Sensor Position Top view and side view (unit: mm) 4/5 Datasheet V1.1 MultiDimension Technology Co., Ltd.
