BQ51013B: RX coil suggestion

pragash sangaran78

Part Number: BQ51013B
Other Parts Discussed in Thread: TIDA-00318,

Tool/software:

The RX coils suggested for this wireless receiver are either obsolete or not available. the coils inside the red box in the picture below are obsolete, and the rest of the coils are not available.

I am afraid to select a new, untested coil based solely on inductance. Has any new Rx coil been tested for this chip?

Hello

The above TDK coil, WR202010-18M8 is good we have used it on TIDA-00318 and other small low power applications. This coil will work well in applications under 500mA output current.

Also take a look at Wurth 760308103215

This is a larger coil 48mm X 32mm and will work well at higher output currents. It is used on new EVMs.

Bill JohnsI'm using BQ51013B, which has a 1.5A output current max. Because of that, the 500mA output will be low. Wurth 760308103215 has a 3A output current. since its tested, I can use this coil to realize the maximum potential of my wireless receiver, BQ51013B. please let me know if my assumption is correct.

Hello

Yes the Wurth 760308103215 can support the higher current your are looking for.
