TB67H303HG
Full Bridge Driver IC for DC motor
The TB67H303HG is a full bridge driver IC for DC motor
adopting MOS in output transistor.
High-power and high-efficient drive is possible by adopting
DMOS output driver with low-ON resistance and PWM drive.

Constant-current PWM control
Constant-current PWM control mode is set when SELECT=H.
The TB67H303HG uses a peak current detection technique to keep the output current constant by
applying constant voltage through the Vref pin.
The ratio 40% of the fast decay mode is always fixed.
Charge-discharge cycles of PWM drive corresponds to 5 cycles of OSCM. The current is decreasing in the
last two OSC cycles; the fast decay mode.
The relation between the master clock frequency (fMCLK), the OSCM frequency (fOSCM) and the PWM
frequency (fchop) is shown as follows:
fOSCM = 1/20 ×fMCLK
fchop = 1/100 ×fMCLK
When Rosc=51kΩ, the master clock=4MHz, OSCM=200kHz, the frequency of PWM(fchop)=40kHz.
NF: Point where output current reaches the setting current.
MDT in the below figure indicates the point of MIXED DECAY TIMMING.
