Hello,

I am trying to monitor the h bridge VNH7100BAS. I want to open HSA and LSB during a certain time then open LSA and LSB. But I do not succeed to do it. I use the tab 'Input A,B' and try to control the H-Bridge with but it does not work.

How can I do it ?

Thanks for your help!

Hi  

Marc-Aurélien ,

thanks for you

interest

on VNH7100BAS device.

If I well understand you question you want to drive the device, so you need to perform the sequence:

I want to close HSA and LSB during a certain time --> INA=PWM=1; INB=0

open LSA and LSB. --> PWM=1; INA=INB=0

For more detail on proper driving  you can refer to figure 12 on related datasheet .

thanks and Best Regards,

Leonardo
