GR7889AANS08ARDQ

GR7889AA is a high-power single-channel DC motor driver IC designed for low-voltage operating systems. It employs an H-bridge driver composed of PMOS and NMOS power transistors with low on-resistance, ensuring low power dissipation during continuous high-current operation and stable long-term performance. The IC features built-in thermal protection: when a low-impedance load motor stalls or an output short circuit causes a sudden surge in current, a sharp rise in power dissipation, and rapid junction temperature increase, if the temperature exceeds the threshold set by the internal protection circuit (typical value 130℃), the internal circuitry will shut down the output to cut off the load current, thereby preventing safety hazards such as smoke or fire in the plastic package due to overheating. An integrated thermal hysteresis circuit ensures that output control is not restored until the junction temperature returns to a safe range. In addition, the IC requires minimal external components, is cost-effective, and is easy to design in.
