DRV8351-SEP is a three phase half-bridge gate driver, capable of driving high-side and low-side N-channel power MOSFETs. The DRV8351-SEPD generates the correct gate drive voltages using an integrated bootstrap diode and external capacitor for the high-side MOSFETs. GVDD is used to generate gate drive voltage for the low-side MOSFETs. The Gate Drive architecture supports peak up to 750mA source and 1.5A sink currents.

The phase pins SHx are able to tolerate significant negative voltage transients; while high side gate driver supply BSTx and GHx can support higher positive voltage transients (57.5V) abs max voltage which improve the robustness of the system. Small propagation delay and delay matching specifications minimize the dead-time requirement which further improves efficiency. Undervoltage protection is provided for both low and high sides through GVDD and BST undervoltage lockout.
