Usage Precautions
・Utmost care is necessary in the design of the output, V
short-circuiting between outputs, air contamination faults, or faults due to improper grounding, or by short-circuiting
between contiguous pins.
・Be sure to install the IC correctly. The IC may be destroyed if installed wrongly (e.g., in reverse).
Note 1: Connect V
Note 2: When connecting the motor pins through the capacitor for reducing noise, connect a resistor to the capacitor
Note 3: Short-circuit S-GND and P-GND as close to the TB6549 as possible.
Note 4: Connect the capacitor C
Note 5: Connect the capacitors C
Note 6: Pins 4, 5, 12, and 13 of the PG type are connected to the bed of the chip. Therefore expanding the round

for limiting the charge current. The switching loss increases for PWM control. Therefore, whenever
practicable, avoid connecting the capacitor if PWM control is required.
