GigaDevice Semicon Beijing GD30DR3000WGTR-K

The GD30DR3000x is an H-bridge driver, and is designed to drive one DC brush motor or other inductive loads. The driver can support up to 3.2A source and sink current. The GD30DR3000x can operate with a single power supply ranging from 6.5V to 40V and VREF voltage of 0.3V to 5V.

The H-bridge is composed of 4 high voltage MOSFET. Two input terminals are provided to control the MOSFETs, and therefore control the speed and direction of the DC motor with externally applied PWM control signals. Integrated current rectification allows the motor driver to regulate the motor current during start up and high load. It also lowers the power dissipation during PWM operation.

The device uses a programmable dead-time and automatic handshaking to prevent the highside and low-side MOSFET from shoot-through when switching. Internal protection includes overcurrent protection, VP undervoltage lock-out and over temperature shutdown.

The versatile features of the IC allow for it to be used in a broad range of applications, such as brush motors, home appliances, etc. The GD30DR3000x is available in a low profile 8-pin SOP with thermal exposed pad.
