Hi,

I want to drive two motor by four  half bridge driver circuit controlled by TLE92104. I followed this parts for HB1:

1-I configurated to BDPASS=0.

2-I set all of half bridges are in high impedance.

3-I selected HB1.

4-I enabled PWM2 for HB1.

5-I set to high side HB1.

At the result GH1 and GH2 are opening.But actually GH2 must be closed.So i cant drive the motor that i want. 

What can I do ?

Thanks.

Hi,

Thanks for the response.

As you mentioned, you set all of the half bridges in high impedance mode. This put bridges in Off-state diagnostics which can be used to detect short to battery/ground or open wire without activating the motor.

To drive the motor, you need to put bridges in HS1/LS2 ON or LS1/HS2 ON mode.

Kindly refer attached link (9.4) -

Please feel free to post in case of any doubt.

Hi,

Thanks for your post.

I need a couple of more inputs to understand this issue better.

1. What is the status of EN pin?

2. Are you using any GUI to configure the resisters? 

3. Kindly share the board details?
