I am trying to build a primary side using bq500210. I built the circuit according to the typical diagram in datasheet of bq500210, the one without MSPG2001.Now power regulator works well, giving a 3.3V supply. Also bq500210 seems to have no problem since LEDS are on when I connect a 100k resistor to the LED_MODE and power the circuit.The problem now is it's unable to detect the coming of bq51013 EVM. And I can see that primary side is continuously sending bytes through the coil, which can be seen at one coil end that is connected to MOSFET(the yellow curve). The green curve is the signal at the other end of coil, the one links to capacitor.Could you please tell me what the problem may be or from where can I start to find the problem?
Hello Connor John
I can help you with this problem.
See Transmitter Design Application note, SLUA635 covers a lot of the common problem with transmitter design and debug.
Would it be possible to work with you using the conversation feature of the forum?
