Notes:
All the grounding wires of the TB67H400AHG must run on the solder mask of the PCB. 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, and 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. Careful attention should be paid to design patterns and
mountings.
