TB67H410NG

Overview

The TB67H410NG is a brushed DC motor driver IC manufactured by Toshiba Semiconductor and Storage. It features a half-bridge output configuration with two independent channels. The device supports a supply voltage range of 10 V to 47 V and delivers an output current of 2 A per channel. It operates within a temperature range of -20°C to +85°C. Key electrical parameters include a maximum power dissipation of 1.78 W, a quiescent current of 5.5 mA, and a switching frequency capability of 70 kHz. The component is housed in a SDIP-24 package designed for through-hole mounting.

Feature Summary

• Integrates dual half-bridge outputs for independent control of two brushed DC motors or one bipolar motor.
• Supports PWM input signals for precise speed and direction regulation of connected loads.
• Incorporates internal protection mechanisms against overcurrent conditions and thermal overload.
• Designed for low standby power consumption suitable for battery-operated applications.

Applications

• Control systems for household appliances such as washing machines and vacuum cleaners
• Industrial automation equipment requiring small to medium DC motor actuation
• Office automation devices including printers and copiers
• Automotive subsystems involving fan or pump motor management

Procurement Notes

Verify the specific ordering suffix and package variant against the official Toshiba datasheet to ensure compatibility with the target PCB footprint. Confirm that the required output current does not exceed the rated 2 A limit under expected operating temperatures. Check RoHS compliance status and lead time requirements directly with authorized distributors prior to finalizing procurement plans.

Selection Notes

Select this component when a through-hole solution is required for driving two separate brushed DC motors or a single bipolar motor. Consider the SDIP-24 package constraints regarding board space and thermal dissipation capabilities. Evaluate whether the 2 A continuous current rating meets the peak load demands of the application without excessive heatsinking requirements.

Part Context

This part belongs to the TB67H series of monolithic brushed DC motor drivers from Toshiba. The series utilizes BiCD technology to integrate logic and power stages on a single chip. Variants within the family differ primarily in output current capacity, package type, and thermal performance characteristics tailored for specific form factor requirements.

Replacement Considerations

TB67H400ANG: Offers higher current capacity but requires verification of pinout compatibility and thermal management differences.
