TB67H302HG

Overview

The TB67H302HG is a dual bridge driver IC for DC motors manufactured by Toshiba Semiconductor and Storage. It operates within a supply voltage range of 8 V to 42 V and supports PWM frequencies up to 100 kHz. The device features an on-resistance (Ron) of 0.4 Ω typical for the upper and lower bridges combined. It includes protection mechanisms such as under-voltage lockout, short circuit detection, and thermal shutdown. The component is housed in a 25-HZIP package with through-hole mounting.

Feature Summary

• Integrates dual full-bridge drivers for independent control of two brushed DC motors
• Provides CW/CCW rotation and short brake/stop functions via logic inputs
• Includes standby function to reduce power consumption during idle periods
• Features built-in protection against under-voltage, over-current, and overheating

Applications

• Industrial automation equipment requiring dual-axis motor control
• Home appliances utilizing brushed DC fans or pumps
• Office automation devices such as printers and scanners
• Robotics platforms needing precise directional motor actuation

Procurement Notes

Verify the specific suffix designation when ordering, as variations may exist. Confirm RoHS compliance status through official Toshiba documentation prior to integration. Ensure the procurement channel provides genuine components from authorized distributors to avoid counterfeit risks. Cross-reference the part number with the latest datasheet revision to confirm pinout and electrical specifications match design requirements.

Selection Notes

Select this component for applications requiring simultaneous control of two brushed DC motors within a 42 V limit. The 0.4 Ω on-resistance supports moderate current loads without excessive heat generation. Consider the 25-HZIP package for through-hole assembly processes. Evaluate thermal management needs based on the expected duty cycle and ambient temperature conditions to ensure reliable operation within the specified -30 C to +85 C range.

Part Context

The TB67H302HG belongs to Toshiba’s TB67H series of motor driver integrated circuits. This series is designed for robust performance in industrial and consumer applications. The HZIP package offers high isolation and thermal dissipation capabilities compared to smaller surface-mount alternatives. It serves as a dedicated solution for driving brushed DC motors where reliability and integrated protection are critical.

Replacement Considerations

The TB67H303HG is a related single-channel variant within the same family. Verify compatibility if substituting for multi-motor designs. No direct cross-brand equivalents are confirmed in public documentation. Check pin-to-pin compatibility and electrical ratings before replacing with other dual bridge drivers.
