Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

Overview:

The DRV8300UDIPWR is a 100V three-phase half-bridge gate driver capable of driving both high - and low-side N-channel power MOSFETs. The DRV8300UD uses an integrated bootstrap diode and external capacitors to generate the appropriate gate drive voltage for the high-side MOSFETs. GVDD is used to generate the gate drive voltage for the low-side MOSFETs. The grid drive architecture supports peak pull currents up to 750mA and fill currents up to 1.5A.

Phase pin SHx can withstand significant negative voltage transients; The high side gate driver power supplies BSTx and GHx can support higher positive voltage transients (125V) absolute maximum, thus improving the robustness of the system. Smaller propagation delays and delay matching parameters minimize dead-time requirements, further improving efficiency. Undervoltage protection for low and high sides with GVDD and BST undervoltage locking.
