Dear Forum Members,

For an automotive project we have selected H bridge driver IC TLE6280 for motor control applications using PWM.

" Below is the procedure mentioned in the manual :
Recommended Start-up procedure
The following procedure is recommended whenever the Driver IC is powered up:
• Disable the Driver IC via DT/DIS pin
• Wait until the bootstrap capacitors of High Side MOSFET CBx are charged (the waiting
time depends on application conditions, e.g. CBx and RBx)
• Enable the Driver IC via DT/DIS pin
• Start the operation by applying the desired pulse patterns. Do not apply any pulse patterns
to the PWM or DIR pin, before the CBx capacitors are charged up
. "

I am new to this chip configuration.

Please somebody share with me the sample code the example of usage of this chip to an advanced level ASAP.

I am controlling this IC using Freescale MPC5606B micro.

Eagerly waiting for an response.

Regards,
RaghavendraP

Steps to do after power up:

- Supply a voltage level of >4V and <5.5V at the disable pin DT/DIS will disable the driver IC. -> Use a pull-up resistor per default while microprocessor's output is high-Z.
- Wait some time (t in ms, depending on the CBx and RBx parts).
- Set a low level to the microprocessor's ouput connected to the DIS (disable) pin to enable the driver.
- After that you can start generating PWM on the ILx/IHx pins.
