Toshiba and MIKROE safety-focused automotive gate driver board

Toshiba’s TB9083FTG has been designed in accordance with ISO 26262 (2nd edition) and integrates 9 gate drivers, including 6 for driving MOSFETs to control BLDC motors in the 1000W range or below. Additionally, it includes 3 drivers for driving external MOSFETs which can be used either for system control or safety relays thus enabling the TB9083FTG to support ASIL-D, the highest level of functional safety for automotive applications. The TB9083FTG also 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 ranging from 4.5V to 28V and can deliver a peak output current of up to 10A. It also features a comprehensive suite of error detection capabilities including undervoltage, overvoltage, over-temperature and an external MOSFET VDS detector making it ideal for demanding automotive applications such as electric power steering (EPS), powered brakes, and automotive pumps where precise motor control is essential.

The Brushless 30 Click board measures only 57.15 mm x 25.4 mm and is fully compatible with the mikroBUS socket. It can be used on any host system supporting the mikroBUS standard and comes with the mikroSDK open-source libraries to provide ultimate flexibility for system evaluation and customisation. An innovative ClickID feature enables a host system to automatically detect and identify the Brushless 30 Click board once it has been connected.
