How are you?:D
Recently I am involving in a project about design a BDC driving board with BTN8962A which is from Infineon . BTN8962A is a half of H-bridge IC.
As we all know,BDC driving circuit is just like this:
In this picture,We set a High side MOS(QA) as Open,and set a High side(QC) and a Low side(QB) MOSes as close.We just have to ouput a PWM signal to control the speed of BDC.
However,I met some troubles when I use Infineon BTN8962,I found I could not do this unless using the INH pin as PWM signal input pin. ( In fact,this pin is sleep mode enable pin.It can close its MOS.)
Which pin should I set as PWM signal output pin? Do I need one more BTN8962A here in order to make a complete H bridge ?
Please give me some help !
Thank you in advance.
