Toshiba and MIKROE develop a safety-focused automotive gate driver board for brushless motors

 

The TB9083FTG is engineered in accordance with ISO 26262 (2nd edition) and features nine gate drivers, including six dedicated to driving MOSFETs for BLDC motors rated at 1000 W or below.  Additionally, it incorporates three drivers for external MOSFETs, which can be utilized for system control or safety relays, enabling the TB9083FTG to support ASIL-D, the highest level of functional safety for automotive applications.  This IC also includes 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 with a wide range of external power supplies from 4.5V to 28V and can deliver a peak output current of up to 10A.  It 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.

 

Measuring just 57.15 mm x 25.4 mm, the Brushless 30 Click board is fully compatible with the mikroBUS™ socket.  It can be used on any host system that supports the mikroBUS™ standard and comes with the mikroSDK open-source libraries, providing ultimate flexibility for system evaluation and customization.  An innovative ClickID feature enables a host system to automatically detect and identify the Brushless 30 Click board upon connection.
