3 General description

The GD30DR8413x integrates three individually controllable half bridge drivers, to drive a 3-

phase BLDC motor or other inductive loads. Each driver is composed of two NMOSFETs 

which support up to 3A source and sink current. The GD30DR8413x can operate with a single 

power supply ranging from 4.5V to 30V. A regulated Bootstrap circuit is integrated in the 

device to supply the high side gate drive currents. Dead time and automatic handshaking is 

applied to prevent the high side and low side NMOSFETs from shoot through when switching. 

Each half bridge has an optional terminal which allows external current sensing. The IC has 

a LDO for both internal circuit and external output up to 20mA. A general purpose comparator 

is also integrated in the device. 

Multiple internal protection features are implemented to prevent the IC and system from 

malfunction damage. The protection includes supply undervoltage lockout, over temperature.

All the protection features are reported through nFAULT pin. 

The versatile features of the IC allow for it to be used in a broad range of applications, such 

as BLDC motors, brushed DC motors, etc. The GD30DR8413x is available in thermal 

enhanced package QFN24.
