TB6552FL General Description

TB6552FN/FL is a dual-bridge driver IC for DC motor with output transistor in LD MOS structure with low ON-resistor. Two input signals, IN1 and IN2, can chose one of four modes such as CW, CCW, short brake, and stop mode. Efficient driven at high temperature is possible by PWM drive system.

TB6556FG General Description

The motor is driven by the square-wave turn-on signal based on a positional signal. When the positional signal reaches number of rotations f = 5 Hz or higher, the rotor position is estimated according to the positional signal and a modulation wave is generated. The modulation wave and the triangular wave are compared; then the sine-wave PWM signal is generated and the motor is driven. From start to 5 Hz: When driven by square wave (120° turn-on) f = f_osc/(2¹² × 32 × 6) 5 Hz~: When driven by sine-wave PWM (180° turn-on); when f_osc = 4 MHz, approx. 5 Hz
