This gate driver is capable of operating with supply voltages (VM) ranging from 8 V to 75 V. The combination of wide operating voltages and currents makes the TB67Z833SFTG suitable for a wide range of use cases.
The devices in this integrated circuit family feature an SPI or hardware control interface for quick and easy configuration, while their low standby current (1 µA max.) helps extend the time between recharges for battery-powered applications. For safety, they include built-in undervoltage lockout and thermal shutdown protection, while gate unit anomaly detection and overcurrent protection enhance overall system reliability by protecting the external MOSFETs.
Toshiba has also adapted the current measurement circuitry in the Clicker 4 Inverter Shield 2 to offer an improved signal-to-noise ratio (SNR), which can be optimized by reducing the peak output current. This expansion board also features Toshiba's TC75W58 dual comparator, which can operate from a single voltage source with low current consumption (20 μA typical). The Clicker 4 Inverter Shield 2 is based on Toshiba's 100 V, low RDS(ON) SSM6K819R power MOSFETs, meeting the growing demand for high-efficiency MOSFETs in smaller package sizes.
The combination of the MIKROE Clicker 4 Inverter Shield 2 and the MIKROE Clicker 4 development board for the Toshiba M4K microcontroller (MCU) offers a practical and cost-effective solution for experimenting with various industrial and consumer brushless DC (BLDC) three-phase motor control applications.
The Clicker 4 Inverter Shield 2 is compatible with the recently updated MCU Motor Studio 4.0 software, which now features a free-running digital storage oscilloscope for comprehensive real-time parameter logging and accommodates all bare-metal configurations. It also introduces support for Shift-2 PWM, improving the precision of hardware-based vector motor control. MMS 4.0 is available for download from the Toshiba website.
