TC78H651FNG,EL

Overview

The TC78H651FNG,EL is a dual-channel brushed DC motor driver manufactured by Toshiba Semiconductor and Storage. It utilizes DMOS technology to provide integrated control and power stages within a 16-TSSOP surface-mount package. The device supports a supply voltage range of 1.8V to 7.5V and delivers an output current of 2A per channel. It operates reliably across a temperature range of -40°C to +105°C with a quiescent current of 600µA. The IC features four half-bridge outputs designed for efficient motor control applications.

Feature Summary

• Integrates full control logic and power stage in a single DMOS IC
• Supports PWM input signals for precise speed regulation
• Includes built-in protection mechanisms against overcurrent and thermal overload

Applications

• Brushed DC motor control in consumer electronics
• Automotive interior actuator systems
• Industrial automation equipment requiring low-voltage motor drive

Procurement Notes

Verify the specific suffix 'FNG' against official Toshiba documentation to confirm pinout and electrical characteristics, as variations exist within the TC78H651 family. Ensure the ordering code matches the exact TSSOP-16 configuration required for your PCB layout. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components.

Selection Notes

Select this component when a compact solution is needed for dual brushed DC motors operating below 7.5V. The low quiescent current makes it suitable for battery-powered devices. Verify that the 2A continuous current rating meets the peak load requirements of the target motors without exceeding thermal limits in the enclosed environment.

Part Context

This part belongs to the TC78H651 series of brushless/brushed motor drivers from Toshiba. It is categorized under PMIC and Motor Drivers. The series is designed to replace discrete MOSFET solutions, reducing board space and simplifying design complexity for standard DC motor applications in portable and automotive sectors.

Replacement Considerations

Check Toshiba datasheets for direct equivalents within the TC78H65x series. Verify pin compatibility before substituting with other manufacturers' dual H-bridge drivers rated for similar voltage and current specifications.
