Hello STM Community,
I'm currently working with the VNQ9080AJTR Quad Channel High-Side Driver, and I'm encountering a couple of issues that I hope someone here can help me resolve
1.Output Voltage Regulation: With a constant VCC supply of 12V, the output of the IC is randomly regulated to 7-8V instead of maintaining a stable 12V output. This issue seems to occur intermittently, and I can't pinpoint a specific trigger for when it happens. Has anyone experienced similar behavior? What could be causing the output voltage to drop unexpectedly?
2.Input Pin Voltage: I have connected the input pin (which is supposed to take signals from the microcontroller) to control the driver, but at times, I'm reading 7-8V at this input pin instead of the expected logic-level voltage.
For both issues, I’ve verified my connections and ensured proper grounding. The behavior is random, making troubleshooting difficult.
