Description:

The GD30DR3820 provides a dual-bridge stepper motordriver solution for cameras, printers, toys, robotics andother mechatronic applications.The device has two H-bridge drivers, drive a bipolarstepper motor. The output driver block consists of Nchannel power MOSFETs configured as an H-bridge todrive the motor winding. An internal charge pumpgenerates gate drive voltages.The GD30DR3820 device has two PWM(IN/IN) inputinterface. Internal shutdown functions with a fault outputpin are provided for overcurrent protection, short circuitprotection, undervoltage lockout, and overtemperature.In addition, GD30DR3820 also supports low-powersleep mode.The GD30DR3820 is packaged in a 16-pin eTSSOP and16-pin QFN package.
