Block Diagram
In the block diagram, part of the functional blocks or constants may be omitted or simplified for explanatory
purposes.
Note: All the grounding wires of the TB62214FG/FTG must run on the solder mask on the PCB and be externally
terminated at only one point. Also, a grounding method should be considered for efficient heat dissipation.
Careful attention should be paid to the layout of the output, VDD (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 TB62214FG/FTG may be
permanently damaged.
Also, utmost care should be taken for pattern designing and implementation of the TB62214FG/FTG since it has
the power supply pins (VM, RS_A, RS_B, OUT_A, OUT_A , OUT_B, OUT_B , GND) particularly a large current can
run through. If these pins are wired incorrectly, an operation error or even worse a destruction of the
TB62214FG/FTG may occur.
The logic input pins must be correctly wired, too; otherwise, the TB62214FG/FTG may be damaged due to a
current larger than the specified current running through the IC.
Please note the above when designing and implementing IC patterns.
