MOTIX™ Bridge

I'm experiencing a strange behavior with one BTN8982TA chip.
I have other chips mounted on other identical boards and they are working fine.

The chip is a High Current PN Half Bridge.
I drive its inhibition pin INH high (to enable it), and its IN with a PWM wave.
So, the output should be a (slew-rate limited, delayed) replica of the PWM.
Instead, the faulty chip generates a strange wave which is always high during the high semiwave of the PWM, and toggles during the low semiwave of the PWM.
During this time interval, the output switches at a frequency of about 7.5kHz and a duty cycle of about 96%.
This frequency and duty cycle is completely independente of the frquency and duty cycle of the PWM applied to the IN pin.

All the oscilloscope screenshot that I'm attaching are taken in a no-load condition, but applying a ~2A load didn't change the behavior.
In the screenshots, the blue trace is the PWM input, the yellow trace is the OUT signal.
See in particular:
01: a working chip, with 18kHz 50% PWM input
02: the faulty chip, with 18kHz 50% PWM input
03: the faulty chip, with 0% PWM applied, showing the 7.5kHz 96% OUT signal
09: the faulty chip, showing the different behavior during high and low phases of the input PWM
04-05-07-08: the faulty chip, with various frequencies and duty cycles for the PWM
06: the faulty chip; at duty cycle > ~95%, it seems to work correctly (but this doesn't work equally well at all frequencies)

I'm also attaching an excerpt of my schematics. Not pictured here, there are also 330uF+330uF+10uF capacitors on VIN.
As far as I can tell, the schematics follows the guidelines and examples given in the datasheet (https://www.infineon.com/dgdl/Infineon-BTN8982TA-DS-v01_00-EN.pdf?fileId=db3a30433fa9412f013fbe32289b7c17).

Hello, I'm looking for an replacement for the BTM7710G. Is there something that is recommended by Infineon to replace the BTM7710 or the older BTM7750. greetings Chris

Hello all,

I have a question about how to set this chip output  high impedance state?

Eg: I want to output_3 pin  to output high impedance state, not high or low level, so how to set this register ?

Thank you very much!
