TC78H600FTG,EL

Overview

The TC78H600FTG,EL is a fully integrated brushed DC motor driver IC manufactured by Toshiba Semiconductor and Storage. It utilizes DMOS technology to provide four half-bridge outputs capable of driving two DC brush motors or one stepper motor. The device operates with a supply voltage range of 2.7V to 5.5V and supports load voltages from 2.5V to 15V. It features an output current capacity of 800mA per channel and accepts PWM interfaces for control. The component is housed in a 24-WQFN (4x4) package with exposed pads and functions within a temperature range of -20°C to +85°C.

Feature Summary

• Fully integrated design combining control logic and power stages for simplified implementation
• Built-in protection mechanisms including over-current detection, thermal shutdown, and under-voltage lockout
• Supports dual H-bridge configuration for independent control of two DC motors or single stepper operation

Applications

• Brushed DC motor control in consumer electronics
• Stepper motor drivers in office automation equipment
• Fan and pump speed control systems

Procurement Notes

Verify the specific suffix EL against the manufacturer's official datasheet to confirm packaging and tape specifications. Ensure the ordering part number matches the exact electrical characteristics required for the target application. Cross-reference the 24-WQFN footprint dimensions during PCB layout to guarantee mechanical compatibility. Confirm RoHS compliance status if environmental regulations apply to the final product assembly.

Selection Notes

Select this component when a low-voltage, fully integrated solution is required for brushed DC or stepper motor applications. The DMOS technology offers efficient switching with minimal external components. Consider the 800mA output limit and 15V load voltage ceiling when sizing for specific motor loads. The wide operating temperature range suits various industrial and commercial environments without requiring extensive thermal management.

Part Context

This part belongs to the TC78H6 series of brushed motor driver ICs from Toshiba. The series is characterized by low-profile packages and silicon monolithic fabrication. These drivers are designed for general-purpose motor control tasks where space efficiency and integrated protection features are prioritized over high-power handling capabilities found in other Toshiba motor driver families.
