描述 Description

The TMAG5170-Q1 is a 3-axis linear Hall effect sensor designed for automotive and industrial applications. This device integrates 3 independent Hall sensors in X, Y, and Z axes. A precision analog signal-chain along with integrated 12-bit ADC digitizes the measured analog magnetic field values. The SPI interface can be used by an external micro-controller to configure the device, start a conversion, or to read back the device register data. On-chip integrated temperature sensor data is available for multiple system functions such as safety check and temperature compensation for a given magnetic field measurement.

The TMAG5170-Q1 can be configured through the SPI to enable any number of magnetic axes and temperature measurements for a particular application. Dedicated ALERT pin enables low-power system operation, and can be used by a micro-controller to trigger a new conversion.

The device is offered in two different orderables for separate magnetic field ranges. Each orderable part can be configured further to select one of three magnetic field ranges that suits the magnet strength and component placements during system calibration. The high level of integration provides flexibility and cost effectiveness in a wide array of sensing system implementations.

The device performs consistently across a wide ambient temperature range of –40 °C to +150 °C.
