TC78H600FNG,C,EL

Overview

The TC78H600FNG,C,EL is a dual-bridge DMOS motor driver IC designed for brushed DC and bipolar stepper motors. It integrates control logic and power stages in a single package. The device operates with a supply voltage range of 2.7V to 5.5V and supports load voltages from 2.5V to 15V. It delivers an output current of 800mA per channel. The component utilizes PWM interface technology and features built-in protection mechanisms including over-current detection, thermal shutdown, and under-voltage lockout. It is housed in a 24-WQFN (4x4mm) surface-mount package.

Feature Summary

• Integrates DMOS output transistors with control circuitry for compact design
• Includes built-in over-current detection and thermal shutdown protection
• Supports PWM signal input for precise motor speed and direction control
• Features under-voltage lockout to ensure stable operation during low voltage conditions

Applications

• Brushed DC motor control in consumer electronics
• Bipolar stepper motor driving in office automation equipment
• Fan and pump speed regulation systems
• General-purpose motion control applications

Procurement Notes

Verify the specific suffix 'C' against official Toshiba documentation to confirm if it denotes a specific tape-and-reel variant or packaging configuration distinct from standard listings. Ensure compatibility with 24-WQFN footprint requirements. Confirm RoHS3 compliance status for your region's regulatory needs before finalizing procurement orders.

Selection Notes

Select this component when a low-profile solution is required for driving two brushed DC motors or one bipolar stepper motor within a 5.5V supply limit. The 800mA output current rating suits light-to-medium duty applications. Consider the integrated protection features for designs requiring reduced external component count and enhanced reliability without additional discrete protection circuits.

Part Context

This part belongs to the Toshiba TC78H6 series of low-profile dual-bridge driver ICs. The series is characterized by silicon monolithic fabrication using DMOS technology. These drivers are engineered to replace multiple discrete components, offering a simplified design path for motor control applications in portable and space-constrained devices.

Replacement Considerations

Consult official Toshiba substitution guides for verified equivalents. Cross-reference pinouts and electrical characteristics carefully when considering alternative manufacturers. Verify that any substitute maintains the same 24-WQFN package dimensions and thermal performance specifications.
