PRODUCTION DATA.
Refer to the PDF data sheet for device specific package drawings
The UVP and POR circuits of the TPA3220 fully protect the device in any power-up/down and brownout situation with PVDD not exceeding the values stated in Absolute Maximum Ratings. While powering up, the POR circuit ensures that all circuits are fully operational when the AVDD supply voltage reaches the value stated in the Electrical Characteristics table. Although AVDD is independently monitored, a supply voltage drop below the UVP threshold on AVDD pin results in all half-bridge outputs immediately being set in the high-impedance (Hi-Z) state and FAULT being asserted low. The device automatically resumes operation when all supply voltages have increased above their UVP threshold.
