Overview
The SX68203M is a sinusoidal three-phase brushless motor driver featuring sensorless vector control. It integrates output transistors, pre-drive circuits, and bootstrap diodes with current-limiting resistors on a single chip. The device utilizes Power MOSFET technology and operates within a supply voltage range of 13.5V to 16.5V. It provides a continuous output current of 1.5A per phase. The component is housed in a 36-SOP package, designed for seamless power management in motor control applications.
Feature Summary
- Integrates output transistors, pre-drive circuits, and bootstrap diodes with current-limiting resistors
- Provides sensorless vector control for sinusoidal three-phase brushless motors
- Includes motor speed indication functionality
Applications
- Three-phase brushless motor drive systems
- General purpose motor control applications
- Sensorless vector control implementations
Procurement Notes
Verify the exact package type and pinout configuration against the official Sanken Electric datasheet before integration. Confirm that the operating supply voltage remains within the specified 13.5V to 16.5V range during system design. Ensure thermal management strategies align with the 36-SOP package limitations for the intended load conditions.
Selection Notes
Select this component when a fully integrated solution for three-phase brushless motors is required without external gate drivers. The inclusion of bootstrap diodes simplifies the bill of materials. Verify compatibility with the target motor's back-EMF characteristics for effective sensorless operation. Check availability as distribution status may vary by region.
Part Context
The SX68203M belongs to the SX68200M series of motor drivers from Sanken Electric. This series focuses on integrating high-voltage power stages with control logic to reduce board space. It serves as a specialized alternative to discrete MOSFET and driver IC combinations, offering a compact solution for industrial and consumer motor applications requiring smooth sinusoidal commutation.
Replacement Considerations
The SX68205M is a related high-voltage three-phase motor drive option from the same manufacturer. Evaluate differences in voltage ratings and current capabilities when considering substitutes. Ensure any replacement maintains the 36-SOP footprint or accommodates necessary mechanical modifications.
