TB67H301FTG
TOSHIBA Bi-CDMOS Integrated Circuit Silicon Monolithic
TB67H301FTG
Full-Bridge DC Motor Driver IC
The TB67H301FTG is a full-bridge DC motor driver with
DMOS output transistors.
The low ON-resistance DMOS process and PWM control
enables driving DC motors with high thermal efficiency.
Four operating modes are selectable via IN1 and IN2: clockwise
(CW), counterclockwise (CCW), Short Brake and Stop.
Features
• Power supply voltage
: 40 V (max)
• Output current
: 3 A (max)
• Direct PWM control
• PWM constasnt-current control
• CW/CCW/Short Brake/Stop
• Overcurrent shutdown circuit (ISD)
• Thermal shutdown circuit (TSD)
• Undervoltage lockout circuit (LVD)
• Dead time for preventing shoot-through current

Absolute Maximum Ratings (Ta = 25°C)
The absolute maximum ratings of a semiconductor device are a set of ratings that must not be exceeded, even for a
moment. Do not exceed any of these ratings.
Exceeding the rating (s) may cause the device breakdown, damage or deterioration, and may result injury by
explosion or combustion.

Reference value
The switching characteristic of the output
transistor strains the frequency.
Reference value
The average output current shall be increased
or decreased depending on usage conditions
such as ambient temperature and IC mounting
method).
Use the average output current so that the
junction temperature of 150°C (Tj) and the
absolute maximum output current rating are
not exceeded.

5. Undervoltage Lockout Circuit (LVD)
The TB67H301FTG incorporates an undervoltage lockout circuit for VM and Vcc.
When VM drops under 4.0 V (typ.), all the outputs are turned off (Hi-Z). The LVD circuit has a hysteresis of
0.2 V (typ.); the TB67H301FTG resumes the normal operation at 4.2 V (typ.).
When Vcc drops under 2.7 V (typ.), all the outputs are turned off (Hi-Z). The LVD circuit has a hysteresis of
0.1 V (typ.); the TB67H301FTG resumes the normal operation at 2.8 V (typ.).
