Hi team,
Here's an issue from the customer may need your help:
How to connect the three Hall sensors of DRV8306? The customer chose a three-pin hall sensor, how should they connect it? Or is the three-pin Hall sensor not acceptable? To use a hall sensor with four pins? If so, what is the recommended model for a four pin hall sensor? How to connect?
Could you help check this case? Thanks.
Best Regards,
Cherry
Hi Cherry,
From the schematic, can you confirm the customer using SS05AT sensor? This seems to be the digital Hall sensor type with open-drain output.
If so, they can still use these sensors if they follow the recommended circuit below using additional resistors.
Refer to the 8.1.1.2 section in the Datasheet: https://www.ti.com/lit/ds/symlink/drv8306.pdf?ts=1648523271202&ref_url=https%253A%252F%252Fwww.ti.com%252Fproduct%252FDRV8306
Once again, please confirm the HS sensor part number. If confirmed, this is also in line with their datasheet recommendation: https://prod-edam.honeywell.com/content/dam/honeywell-edam/sps/siot/en-us/products/sensors/magnetic-sensors/bipolar-position-sensor-ics/common/documents/sps-siot-ss30at-ss40a-ss50at-product-sheet-005906-1-en-ciid-50355.pdf?download=false
