TLE4972-AE35S5
Coreless Hall current sensor with stray-field immunity for +/-35 A inverter, drive and battery-current measurement.
Stray-field-immune coreless current sensor with differential Hall sensing for ±35 A measurement in inverter, drive and battery management applications.
FAE Professional Review
The TLE4972 eliminates the ferrite core entirely, which removes saturation limits and greatly simplifies PCB assembly. The differential sensing structure rejects stray fields from adjacent phases, so you can route the sensor close to switching paths. Plan the conductor layout carefully: the sense current path is part of the calibration, and our application notes cover the recommended copper geometry.

Frequently Asked Questions
What is the TLE4972-AE35S5 best used for?
It is a coreless Hall current sensor for ±35 A measurement in traction-inverter phase sensing, battery management and industrial drive feedback. Stray-field immunity lets you place it close to switching paths.
Confirm your peak current against the ±35 A range before selecting.
How do I lay out the sense conductor for accuracy?
The conductor geometry is part of the sensor calibration, so follow the recommended copper width, thickness and symmetry from the datasheet. Avoid asymmetric routing that shifts the field.
Our application notes cover the recommended PCB geometry.
How do I connect its analog output to my MCU?
The analog output scales directly into an MCU ADC; add an anti-alias filter matched to your sampling rate and keep the reference stable. The differential sensing structure already rejects adjacent-phase fields.
Ask us to match the output to your ADC input range.
How does it compare with a shunt-based measurement?
A Hall sensor removes the shunt's power loss and isolation concerns while retaining accuracy, and the coreless design avoids saturation. Shunts can still win on cost for low currents.
Discuss the trade-off with our FAE team for your current range.
What temperature and installation issues should I consider?
Keep within the -40 to +125 °C range, avoid placing the sensor next to strong magnetic components, and account for self-heating of the conductor. The compact PG-TDSO-16 package suits automated assembly.
Request a layout review to confirm placement.
