TC78H630FNG,EL

Overview

The TC78H630FNG,EL is a bipolar motor driver IC manufactured by Toshiba Semiconductor and Storage. It utilizes DMOS technology for PWM control of brushed DC motors or bipolar stepper motors. The device features a half-bridge output configuration within a 16-TSSOP package. It operates with a supply voltage range of 2.7V to 5.5V and supports load voltages from 2.5V to 15V. The maximum output current is rated at 2.1A, with a typical operating supply current of 500 uA. It functions within a temperature range of -30°C to +85°C.

Feature Summary

• Integrates DMOS output transistors for efficient PWM motor control
• Includes built-in over-current detection and thermal shutdown protection
• Features under-voltage lockout for stable operation

Applications

• Brushed DC motor drive systems
• Bipolar stepper motor control
• General purpose motion controllers

Procurement Notes

Verify the specific suffix EL against official Toshiba documentation to confirm packaging and material specifications. Ensure compatibility with system voltage requirements, as the supply range is limited to 2.7V–5.5V while load voltage extends to 15V. Confirm that the 16-TSSOP footprint matches the target PCB layout. Cross-reference RoHS compliance status with current regulatory standards before finalizing procurement.

Selection Notes

Select this component when designing circuits requiring dual-channel half-bridge control for low-voltage DC or stepper motors. The DMOS architecture offers lower on-resistance compared to older BJT technologies. Consider the 500 uA standby current for battery-operated applications. Verify that the thermal dissipation capabilities of the TSSOP package are sufficient for the expected load current in the specific enclosure environment.

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 integrated safety features such as thermal shutdown and under-voltage lockout. These ICs are silicon monolithic devices designed for driving two DC brush motors or one stepping motor in consumer electronics and industrial automation applications.

Replacement Considerations
