TB6556F TOSHIBA [Toshiba Semiconductor], TB6556F Datasheet - Page 19

• Manufacturer Part Number: TB6556F
• Description: 3-Phase Full-Wave Sine-Wave PWM Brushless Motor Controller
• Manufacturer: TOSHIBA [Toshiba Semiconductor]

Example of Application Circuit
MCU
Note 1: Connect to ground as necessary to prevent IC malfunction due to noise.
Note 2: Connect GND to signal ground on the application circuit.
Note 3: The device may be damaged by short circuits between outputs or between output and supply or ground. Peripheral parts may also be damaged by overvoltage and overcurrent. Design the output lines, V
lines to ensure that no short circuits occur.
Be careful also not to insert the IC in the wrong direction since this may destroy the IC.
