Typical Application Diagram
Note 1: Connect VCC and P-GND through the power supply capacitor. This capacitor should be as close as possible
to the IC.
Note 2: When connecting the motor pins through the capacitor for reducing noise, connect a resistor to the capacitor
for limiting the charge current. The switching loss increases for PWM control. Therefore, whenever
practicable, avoid connecting the capacitor if PWM control is required.
Note 3: Short-circuit S-GND and P-GND as close to the TB6549 as possible.
Note 4: Connect the capacitor C3 to S-GND.
Note 5: Connect the capacitors C1 and C2 as close to the TB6549 as possible, and the capacitor C1 as close to
S-GND.
Note 6: Pins 4, 5, 12, and 13 of the PG type are connected to the bed of the chip. Therefore expanding the round
area of these pins improves the heat radiation effect.
Usage Precautions
·
Utmost care is necessary in the design of the output, VCC, VM, and GND lines since the IC may be destroyed by
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).
TB6549FG: Pins 1, 5, 6, 9, 13, 15, 16, and 19 are not connected.
TB6549HQ: Pins 4, 6, 8, 9, 13, 17, 18, 20, 21, 22 are not connected.
