TB67H450FNG
Block Diagram
VM VCC Regulator Charge UVLO Pump OUT1 IN1 ISD Control Logic H-Bridge IN2 Pre-driver OUT2 TSD Up to 5V Current Comp VREF GND RS Some of the functional blocks, circuits, or constants in the block diagram may be omitted or simplified for explanatory purposes. Note: All the grounding wires of the TB67H450FNG 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, OUT1, OUT2, 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. 3 2019-04-01
