TI DRV5053OAQDBZRQ1

The DRV5053-Q1 device is a chopper-stabilized Hall IC that provides a magnetic field sensing solution with excellent sensitivity stability and integrated protection features over the entire temperature range. The 0V to 2V analog output provides a linear response to the applied magnetic induction and can distinguish the polarity of the magnetic field direction. The wide operating voltage range (2.7V to 38V) with reverse polarity protection up to -22V makes this device suitable for a wide range of automotive and consumer applications. Internal protection functions are provided for reverse power supply conditions, load dump, and output short-circuit or overcurrent.

The DRV5053-Q1 device is a chopper-stabilized hall sensor with an analog output for magnetic sensing applications. The DRV5053-Q1 device can be powered with a supply voltage between 2.7 and 38 V, and will survive -22 V reverse battery conditions continuously. Note that the DRV5053-Q1 device will not be operating when approximately -22 to 2.4 V is applied to VCC (with respect to GND). In addition, the device can withstand supply voltages up to 40 V for transient durations.

The output voltage is dependent on the magnetic field perpendicular to the package. The absence of a magnetic field will result in OUT = 1 V. A magnetic field will cause the output voltage to change linearly with the magnetic field.

The field polarity is defined as follows: a south pole near the marked side of the package is a positive magnetic field. A north pole near the marked side of the package is a negative magnetic field.

For devices with a negative sensitivity (that is, DRV5053-Q1RA: -40 mV/mT), a south pole will cause the output voltage to drop below 1 V, and a north pole will cause the output to rise above 1 V.

For devices with a positive sensitivity (that is, DRV5053-Q1EA: +40 mV/mT), a south pole will cause the output voltage to rise above 1 V, and a north pole will cause the output to drop below 1 V.
