The TB9053 DC-motor driver IC from Toshiba Electronics Europe has been integrated into the MikroElektronika (MIKROE) DC Motor 26 Click Board to expedite the development of automotive motor control.
The TB9053 benefits from a dual H-bridge output stage, capable of driving two motors at up to 5A or a single motor up to 10A. The solution features built-in protection and diagnostic technologies, in addition to extra circuitry to save external components including charge-pump capacitors. Additional features of the TB9053 include its thermally enhanced QFN40 package and simplified design to enable the use of compact ECUs.
Following its integration with the MIKROE DC Motor 26 Click Board, the TB9053 can be designed into throttle valves, engine valves, powered mirrors, grille shutters, seat heaters and door opening/closing mechanisms.
The DC Motor 26 Click Board connects directly to microcontroller development boards which support the mikroBUS interface. The motor can be controlled through the mikroBUS socket using a PWM signal (CLK) or the TB9053’s SPI serial interface.
PWM or SPI control can be selected using switches that also control the selection of single- or dual-motor modes, and additional header pins enable motor forward, reverse, brake, drive and stop commands depending on the control mode. The board accepts a 3.3V or 5V input voltage and enables a separate supply for the TB9053 to power the motors at a voltage from 4.5V to 28V.
