TB67H400AFTG,EL

Overview

The TB67H400AFTG,EL is a monolithic brushed DC motor driver IC manufactured by Toshiba Semiconductor and Storage. It integrates four half-bridge power stages using power MOSFET technology, delivering an output current of 6A. The device operates with a supply voltage range of 4.75V to 5.25V and supports load voltages from 10V to 47V. It accepts parallel and PWM interfaces for control. The component is housed in a 48-WQFN (7x7) package with exposed pad, suitable for surface mount installation. It functions as a fully integrated driver with both control logic and power stages included.

Feature Summary

• Integrates four half-bridge outputs utilizing power MOSFET technology for efficient motor driving
• Supports constant current control via PWM interface alongside CW/CCW/Short Brake/Stop modes
• Includes standby function to reduce power consumption during idle periods

Applications

• Brushed DC motor control in general industrial equipment
• Motion control systems requiring high current drive capabilities
• Automotive interior mechanisms such as seat adjusters or window lifts

Procurement Notes

Verify the specific suffix EL against the manufacturer's official datasheet to confirm pinout and thermal pad configuration. Ensure the ordering quantity aligns with the standard factory packaging requirements specified by Toshiba. Cross-reference the RoHS status and moisture sensitivity level with your assembly process standards before finalizing procurement.

Selection Notes

Select this component when a single-chip solution for four-channel brushed DC motor control is required. It is appropriate for designs needing 6A continuous output current within a compact 48-pin WQFN footprint. Consider the 4.75V to 5.25V supply constraint when designing the power rail compared to wider voltage range alternatives.

Part Context

This part belongs to the TB67H400 series of brush motor driver ICs from Toshiba. It is designed for applications requiring robust motor control with integrated protection features. The AFTG variant specifically denotes the WQFN package type, distinguishing it from HTSSOP versions like the AFNG series within the same functional family.

Replacement Considerations

The TB67H400AFNG,EL serves as a pin-compatible alternative offering identical electrical performance but utilizes a 48-HTSSOP package instead of WQFN. Designers must account for the physical footprint differences when substituting between these package types.
