Part Number: DRV411
In the application note related to this part (TIPD180) Tom suggests the use of Topstek's TQPL50A passive closed-loop symmetric hall effect current sensor.The aforementioned sensor doesn't seem to be an easy part to get ahold of, moreover there doesn't seem to be a similar symmetric sensor in the manufacturer's product range. To be honest, I'm struggling to find any such sensors at all out there.Could anyone point me in the right direction as to which commercially available sensors could work well with the DRV411 chip?
Many thanks in advance and kind regards,

The Topstek device TQPL50A was never released. There is currently no complete sensor available that I know of.
You would need to use a hall sensor like the HW-322B along with a magnetic core to concentrate and force the flux through the hall sensor. I am sorry to say I have not been able to find a magnetic core off the shelf. You would need to work with a magnetic core manufacture to get this done.

Hi Javier,Many thanks for the prompt response.I was hoping I'd be able to avoid having to go the bespoke sensor way but no worries, I'll see what's available.There's another thread in which someone claims to have been using the IC for a long time, it would be interesting to know which sensor they have been using. Just a thought.
