BQ51050B: BQ51050B

Part Number: BQ51050B
Other Parts Discussed in Thread: TIDA-00669

Based on TIDA-00669, we decided to implement a battery charger with the BQ51050B using the small coil of Würth elektronik model 760308103206 that appears there. This is because of the size is a critical requeriment in our application and we can´t use a bigger size coil.

 

-          With respect to TIDA-00669, can the 760308103206 coil give  the enough transfered energy to the regulator  for achieving 480 mA output current at 4.2 V out? I ask it because of the coil size.

 

As transmitter we want to use a P9038 IDT Tx, Are this transmitter (P9038) and this receiver (BQ51050B) compatibles?  

Thank´s in advance

  • The Wurth coil is 28mm X 15mm with L of 7.5uh. A larger coil with higher L would be better. If the coil to coil distance is low and alignment is good this one will work.
    BQ5105X are designed to work with Qi compatible transmitters.
