Frequently Asked Questions
What magnetic field range and output interface does the TMAG5273A1QDBVT provide for 3-axis sensing?
The TMAG5273A1QDBVT measures magnetic flux density from -80 mT to +80 mT on all three axes (X, Y, and Z) simultaneously. Data is read via a standard I2C interface, eliminating the need for ADC inputs on the host microcontroller. This makes it suitable for detecting both magnitude and direction of fields generated by permanent magnets in position or rotation sensing applications.
How does the TMAG5273A1QDBVT's power consumption compare to traditional analog Hall-effect sensors in a duty-cycled IoT node?
The TMAG5273A1QDBVT draws up to 3 mA during active conversion but supports low-power sleep modes that reduce average current dramatically when duty-cycled. A traditional analog Hall sensor requires continuous biasing and an ADC, often consuming more total system power. In a node sampling at 1 Hz with 1 ms active windows, average current falls well below 10 µA, enabling years of operation from a 1000 mAh battery.
Is the TMAG5273A1QDBVT suitable for automotive shaft angle sensing in an engine bay, and what qualification does it carry?
Yes, the TMAG5273A1QDBVT is AEC-Q100 qualified, meeting automotive reliability standards for use in engine bay and powertrain environments. It operates across the full automotive temperature range and provides contactless ±80 mT 3-axis field measurement via I2C, which is sufficient for sensing angles generated by small diametrically magnetized permanent magnets placed on rotating shafts in throttle, pedal, and valve position applications.
What PCB footprint area does the 6-pin SOT-23 package of TMAG5273A1QDBVT require, and how does this affect sensor placement near a magnet?
The 6-pin SOT-23 package measures 2.9 mm × 1.6 mm with a body height of 1.1 mm, occupying less than 5 mm² of board area. This compact size allows the sensor to be placed within 1–3 mm of a target magnet on the PCB, maximizing coupling efficiency. It also enables integration directly inside motor housings or behind thin plastic enclosures for mechanical protection without sacrificing sensing accuracy.
