TB6562AFG is a type of motor driver integrated circuit (IC) produced by Toshiba. This motor driver IC is classified under PMIC (Power Management ICs) which controls and monitors the motors. It is used to drive three-phase brushless dc motors with efficient power control. This motor driver IC is used for position control of floppy disk\'s spindle motor and to drive a compressor in a fridge. It can also be used in cameraphone\'s autofocus, robotics and other similar industrial automation systems.

The TB6562AFG is controlled by 8 signals and an external 8-bit shift register (EL). These signals include steps, dir, full-step, half-step, prohibit, reset, S1 and S2. The Directory (dir) is used to select direction of rotation. With the steps signal, motor can be step-controlled in full or half step operation. If the steps signal is not used, full-step operation will occur. When prohibit is set to a logic high, power off logic output signal is set to low and all logic input pins are ignored. S1 and S2 signal helps in setting full-step excitation pattern.

The external 8-bit shift register (EL) is used to set the output steps of the motor driver. When data bits are shifted into the shift register, driver will respond according to the data and the motor will rotate accordingly. The number of steps required to rotate the motor can be specified with the shift register. Depending on the data transmitted through the shift register, the motor can be rotated in a certain number of steps.

TB6562AFG is designed to provide an efficient power control in a cost-effective manner. It requires very low power to drive the motors and provides high power efficiency. This is due to the on-chip gate driver, PWM control and sophisticated logic circuit. Its gate drivers are highly resistant to electro-magnetic interference. Its internal thermal shutdown circuit protects the chip from thermal over-heating during over-current scenarios.

In summary, TB6562AFG is a motor driver IC from Toshiba which is categorized under PMIC (Power Management ICs). This motor driver IC is used to drive three-phase brushless dc motors and is used for position control in industrial automation systems. It is controlled by 8 signals and an external 8 bit shift register (EL). This motor driver IC provides an efficient power control and is highly resistant to electro-magnetic interference.
