TB67H410FTG , TB67H410NG
TOSHIBA BiCD Integrated Circuit Silicon Monolithic
TB67H410FTG, TB67H410NG
PWM Chopper-Type
Brushed DC Motor driver
The TB67H410 is brushed DC motor driver of a PWM chopper-type.
The TB67H410 is a dual channel H-SW driver which can control
two brushed DC motors. Moreover, the parallel control function (La
rge mode) of an output part is built in, and 1ch high current drive is
also possible.Fabricated with the BiCD process, the TB67H410 is
maximum rated at 50V,2.5A(2ch)/5.0A(1ch).

Notes:
All the grounding wires of the TB67H410 must run on the solder within the mask of the PCM. It must also be
externally terminated at a single point. Also, the grounding method should be considered for efficient heat dissipation.
Careful attention should be paid to the layout of the output, VM and GND traces, to avoid short circuits across output
pins or to the power supply or ground. If such a short circuit occurs, the device may be permanently damaged.
Also, the utmost care should be taken for pattern designing and implementation of the device since it has power
supply pins (VM, RS, OUT, GND) through which a particularly large current may run. If these pins are wired
incorrectly, an operation error may occur or the device may be destroyed.
The logic input pins must also be wired correctly. Otherwise, the device may be damaged owing to a current running
through the IC that is larger than the specified current.
