Typical Application Diagram
Note 1: Connect V
CC
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 TB6549 as possible.
Note 4: Connect the capacitor C
3
to S-GND.
Note 5: Connect the capacitors C
1
and C
2
as close to TB6549 as possible, and the capacitor C
1
as close to S-GND.
Note 6: Pins 4, 5, 12, and 13 of the P type are connected to the chip’s bed. Therefore, expanding their round area
produces a better heat radiation effect.
Usage Precautions
This IC includes an overcurrent detection circuit. However, if a short circuit takes place between output pins or
if an output pin is connected to the voltage source or ground, a heavy current temporarily flows through the IC.
It might destroy the IC. This possibility should be fully considered in the design of the output line, V
CC
line,
and GND line. If the IC is destroyed, a heavy current might continuously flow through it as a secondary effect.
Therefore, Toshiba recommends that a fuse be connected to the power supply line.
Install this IC properly. If not, (e.g., installing it in the wrong position), the IC might be destroyed.
TB6549F: Pins 1, 5, 6, 9, 13, 15, 16, and 19 are not connected.
