DRV8353F: How to determine 'Target output rise time' and 'Target output fall time'

Robert Huang

Part Number: DRV8353F

Tool/software:

In datasheet DRV835xF, it mentioned Design Parameters in Table 9-1 in 9.2.1.1 section and there are 'Target output rise time' and 'Target output fall time' values. How do we determine their values? Any dependency?

Hey Robert,

The rise and tfall refer to the time taken for VDS voltage across the MOSFET to rise and fall respectively. This is adjusted using the Idrive setting.

Please refer to this E2E FAQ on how to configure the Idrive setting based on your MOSFET QGD.

Please mark the thread as resolved if it answered your question.

Best,
