3 Description

DRV8300 is 100-V three half-bridge gate drivers,

capable of driving high-side and low-side N-channel

power MOSFETs. The DRV8300D generates the

correct gate drive voltages using an integrated

bootstrap diode and external capacitor for the highside

MOSFETs. The DRV8300N generates the correct

gate drive voltages using an external 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 (125-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.
