DRV8300 -Q1 is 100-V three half-bridge gate drivers, capable of driving high-side and low-side N-channel power MOSFETs. The DRV8300 -Q1 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 750-mA source and 1.5-A sink currents.
The phase pins SHx is able to tolerate the significant negative voltage transients; while high side gate driver supply BSTx and GHx is able to support to higher positive voltage transients (115-V) abs max voltage which improves 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 side through GVDD and BST undervoltage lockout.
