DRV8412: BST_UVP threshold

Part Number: DRV8412

Hi all

Would you mind if we ask DRV8412?
Is BST_UVP the voltage threshould between BST_X and OUT_X?
Is our recognition correct?

Kind regards,

    Hi Hirotaka-san,

    Yes. you're understanding is correct. For proper driver operation, the bootstrap capacitor voltage needs to be above a certain level. If the voltage drops below this level, the BST_UVP protection will kick in and recharge the capacitor to a safe level.
