SI-6633C

Overview

The SI-6633C is a multiphase motor driver power MOSFET manufactured by Sanken Electric USA Inc. It operates within an operating supply voltage range of 10 to 30 V and supports a minimum operating temperature of -20 °C. The component is housed in a 36-QFN (6x6) package with surface mount mounting. It is designed for brushless DC motors and stepper motors.

Feature Summary

• Enables shutdown functionality
• Provides dead-time control
• Includes overcurrent protection
• Supports three-phase operation

Applications

• Brushless DC Motor control
• Stepper Motor control
• Multiphase Motor Driver applications

Procurement Notes

Verify the current product status, as sources indicate this part may be marked as Not For New Designs or NRND. Confirm availability through authorized distributors, as stock levels vary. Ensure the 36-QFN package matches your PCB layout requirements before ordering.

Selection Notes

Select this component for applications requiring integrated pre-driver features for BLDC and stepper motors. Consider the 10-30V supply voltage range and -20°C minimum operating temperature when designing the system environment. Verify compatibility with external N-channel MOSFETs if using the device as a pre-driver.

Part Context

The SI-6633C belongs to the Motor Drivers, Controllers category from Sanken Electric. It functions as a multiphase motor driver power MOSFET. The device is distinct from other Sanken products like the SI-3050C, which is a low dropout voltage dropper type regulator.
