Required IC to measure AC Current and AC Voltage

Other Parts Discussed in Thread: DRV421, DRV411

Hello Sir/Mam

I need one chip from TI which is capable of measuring Single Phase AC current and AC voltage of the load (Street Lighting).Its function should be similar as MAXQ314.

Are there any Hall Sensor ICs which can measure AC voltage and current and send the information to Microcontroller.

Waiting for feedback.

With Regards,

Hi Suneetha, we do have this TI Design, which uses a flux concentrator around a cable: http://www.ti.com/tool/TIDA-00218

Is there a certain bandwidth you need?

Best regards,

Hi Suneetha,

For measuring current we have our DRV421 that requires a magnetic core with windings. We have a reference design that goes up to 15A but could be increased or decreased. We also have a DRV411 that uses a concentrator along with a hall sensor to measure the current.

Regards,

Javier

Hello Sir,

We want an IC from TI which is similar to the functionality of MAXQ314.We don't want to use any windings.

Suggest any other IC which is similar to MAXQ314.
