Datasheet TMR130 (MDT) - 9

TMR130x
MicroAmpere High Frequency Response Omnipolar Magnetic Switch Sensor 9. Application Information It is recommended to add a filter capacitor between Common failure conditions: the sensor power supply and ground (close to the • The supply voltage exceeds the limit of absolute sensor) to reduce external noise. As shown in Figure maximum ratings 23, the typical value is 0.1 μF. •Absence of matching filter capacitor to power supply when the power supply is unstable, which can TMR cause the product to restart repeatedly Switch • Using switch output V V OUT to control high-power CC relays, etc., and cause ISINK and ISOURCE exceeding 0.1μF V V OUT the limit of absolute maximum ratings GND • The external magnetic field exceeds the limit of absolute maximum ratings • Operating in a humid environment for a long time, causing vapor penetration and increased power consumption Figure 23. Application circuit diagram • Overheating when soldering • Over bending of pins The TMR130X series sensor chips are not suitable for driving power loads. The general method of use is utilizing the output voltage of VOUT pin as a signal to input the MCU or drive a triode or MOS as shown in Figure 24. Triode/MOS B/G TMR Switch VOUT MCU IO Figure 24.
