Description：

The GD30DR3002 is an H-bridge driver, and is designedto drive one DC brush motor or other inductive loads.The H-bridge is composed of four high voltage NChannel MOSFETs that can control motorsbidirectionally with up to 6A peak current. Two logicinputs are provided to control the H-bridge driver, andtherefore control the speed and direction of the DCmotor with externally applied PWM control signals.Setting both inputs low enters a low power sleep mode.At the same time, the device also has a fault statusindication function.The GD30DR3002 device features integrated currentregulation, based on the internal reference voltage andthe voltage on the ISEN pin, which is proportional tomotor current through an external sense resistor. Theability to limit current to a known level can significantlyreduce the system power requirements and bulkcapacitance needed to maintain stable voltage,especially for motor startup and stall conditions.The device internal protection includes undervoltage(UVLO), overcurrent(OCP), and overtemperature(TSD).When the fault condition is removed, the deviceautomatically resumes normal operation.
