TC78B004AFTG,EL

Overview

The TC78B004AFTG,EL is a multiphase motor driver manufactured by Toshiba Semiconductor and Storage. It utilizes NMOS technology with PWM control to drive brushless DC motors. The device operates within a supply voltage range of 10V to 28V and delivers an output current of 100mA. It is housed in a 40-WQFN (6x6) package designed for surface mount installation.

Feature Summary

• Integrates full-wave sine-wave PWM driving capabilities for brushless motor control
• Includes built-in speed control functionality
• Utilizes NMOS output configuration for efficient power management

Applications

• Brushless DC motor speed control systems
• Multiphase motor driver circuits
• Fan controller applications

Procurement Notes

Verify the specific suffix EL indicates tape and reel packaging when ordering. Confirm the 40-WQFN package dimensions match the PCB footprint requirements. Ensure the 10V-28V supply range aligns with the target system voltage. Check RoHS compliance status for environmental regulations.

Selection Notes

Select this component for applications requiring integrated sine-wave PWM generation and speed regulation. The 100mA output current suits low-power BLDC loads. The WQFN package offers compact board space utilization compared to larger packages. Verify thermal dissipation needs for the 6x6mm footprint.

Part Context

This part belongs to Toshiba's brushless motor controller series, specifically designed for precise speed control. It integrates control logic and power drivers into a single IC, reducing external component count. The family focuses on efficient NMOS-based solutions for consumer and industrial electronics.

Replacement Considerations

Check datasheets for compatible parts with similar 100mA output and 40-pin QFN packages. Verify pin-to-pin compatibility if substituting directly. Ensure equivalent PWM frequency ranges and supply voltage tolerances are met by alternative candidates.
