Hello,

Is the schematic for the bq78PL116 EVM available? It's missing from the EVM's User Guide, SLUU474.

Are the Gerber files for the EVM also available?

Thank you!

    Hello,Jim

    I have some problems with bq78PL116EVM to ask you. I used Buck circuit to charge the lithium battery and connect the buck circuit I designed to the 116EVM. I use DSP2812 to control the drive module of buck circuit. And when the load is resistor, the buck circuit works well, But when I connected the buck circuit to Pack+ and Pack- of 116EVM, it didn't work and the EVM was brocken.The bqwizard software can't read the information of the EVM. The SMBus communication was interrupted. The software indicated that the SMBus has an error. So do you know the reason for this?

    And how to solve the problem?

     

    Thanks
