SPF7302

Overview

The SPF7302 is a single-chip full-bridge driver IC designed for DC brush motor applications. It supports a supply voltage range of 6V to 18V and delivers a continuous output current of 3A, with a peak pulsed current capability of 6A at 1 kHz. The device operates within an ambient temperature range of -40°C to 105°C. It integrates comprehensive protection features including overcurrent, thermal shutdown, and undervoltage lockout, ensuring robust performance in general-purpose motor control scenarios.

Feature Summary

• Single-chip full-bridge architecture for DC brush motor drive
• Integrated overcurrent, thermal, and undervoltage protection
• Capable of handling 3A continuous and 6A pulsed currents

Applications

• General purpose DC brush motor control
• Consumer electronics small appliances
• Industrial automation motor drives

Procurement Notes

Verify the specific package variant and manufacturer revision level against the official Sanken Electric datasheet before procurement. Confirm that the intended operating voltage and current loads remain within the specified 6V–18V supply and 3A continuous limits. Ensure thermal management strategies align with the -40°C to 105°C operating temperature range to maintain reliability and prevent triggering of internal protection circuits during sustained operation.

Selection Notes

Select this component when a compact, fully integrated solution for DC brush motors is required. It is suitable for designs needing built-in protection mechanisms to simplify board layout and reduce external component count. Consider its 3A continuous current rating and 18V maximum supply voltage to ensure compatibility with the target motor specifications and power supply constraints.

Part Context

The SPF7302 belongs to Sanken Electric's family of motor drivers and controllers. It is specifically engineered as a full-bridge driver IC, distinguishing it from half-bridge or unipolar stepper drivers. This classification makes it appropriate for bidirectional control of brushed DC motors, offering a complete driving solution in a single semiconductor package.

Replacement Considerations

Consult official Sanken Electric documentation for confirmed substitute part numbers. Do not assume cross-compatibility with other manufacturers' full-bridge drivers without verifying pinout, electrical parameters, and protection feature alignment.
