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 P/PG type are connected to the bed of the chip. Therefore expanding the round
Note 7: Pins 2 and 5 of HQ type must be shorted outside.

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