Toshiba and MIKROE develop automotive gate driver board for brushless motors
Toshiba Electronics Europe has teamed up with development tools supplier MikroElektronika (MIKROE) to integrate its TB9083FTG gate-driver IC into the Brushless 30 Click, a compact add-on board for precise and reliable control of brushless DC (BLDC) motors in automotive applications.
Toshiba’s TB9083FTG has been designed in accordance with ISO 26262 (2nd edition) and integrates nine gate drivers, including six for driving MOSFETs to control BLDC motors in the 1000 W range or below.
It also includes three drivers for external MOSFETs that can be used either for system control or safety relays, thus enabling the TB9083FTG to support the ASIL-D functional safety standard for automotive applications.
The TB9083FTG incorporates a built-in charge pump, adjustable current sense amplifiers for each motor phase oscillator circuit and an SPI communication interface for configuration via a host microcontroller unit (MCU).
The Brushless 30 Click board is designed to operate from a wide range of external power supplies from 4.5 V to 28 V and can deliver a peak output current of up to 10 A. It features a suite of error detection capabilities including undervoltage, overvoltage, over-temperature and an external MOSFET VDS detector for demanding automotive applications such as electric power steering (EPS), powered brakes and automotive pumps where precise motor control is essential.
