TB67H400AHG

Overview

The TB67H400AHG is a monolithic brushed DC motor driver IC manufactured by Toshiba Semiconductor and Storage. It utilizes BiCD technology with power MOSFETs to provide integrated control and power stages. The device supports parallel and PWM interfaces for constant current control, CW/CCW rotation, short brake, stop modes, and standby functions. It features four half-bridge outputs capable of delivering up to 6A output current. The load voltage range is specified from 10V to 47V, while the supply voltage operates between 4.75V and 5.25V. The component is housed in a 25-HZIP through-hole package and is rated for junction temperatures ranging from -20°C to 150°C.

Feature Summary

• Integrates full control logic and power stage into a single monolithic chip using BiCD technology.
• Supports multiple operational modes including continuous wave, counter-clockwise, short brake, and stop functions.
• Enables precise motor control via constant current regulation using PWM signals.
• Includes a standby function to reduce power consumption when the motor is inactive.

Applications

• Brushed DC motor control in general-purpose industrial equipment
• Motion control systems requiring bidirectional rotation and braking
• Automotive subsystems compatible with 12V or 24V electrical architectures

Procurement Notes

Verify the specific suffix and packaging configuration against the manufacturer's official datasheet to ensure compatibility with the intended assembly process. Confirm that the through-hole HZIP25-P-25 package aligns with the PCB footprint requirements. Check RoHS compliance status and moisture sensitivity level (MSL 3) for storage and handling procedures. Ensure the operating temperature range meets the environmental conditions of the final application.

Selection Notes

Select this component when a robust, high-current brushed DC motor solution is required with integrated protection and control features. The 6A output capability suits applications demanding significant torque or speed control. Consider the through-hole mounting option if mechanical stability or thermal dissipation through the lead frame is prioritized over surface area constraints. Verify that the 47V maximum load voltage covers the system's peak back-EMF scenarios.

Part Context

This part belongs to the TB67H400 series of brushed DC motor drivers from Toshiba. It shares functional similarities with other variants like the TB67H400AFNG but differs in package type and mounting style. The series is designed for applications requiring reliable motor control with minimal external components. The AHG variant specifically offers a through-hole package, distinguishing it from surface-mount alternatives within the same product family.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Users should consult the manufacturer's official replacement guide or cross-reference list for verified equivalents. Direct pin-to-pin replacements may require verification of electrical parameters and thermal characteristics.
