Toshiba has launched four products of TB67Z83xxFTG Series three-phase gate driver ICs and four products of TB67Z85xxFTG Series three-phase gate driver ICs for three-phase brushless DC motors used for consumer and industrial equipment. By combining the new products with a microcontroller as a motor controller and MOSFETs, it is possible to drive brushless DC motors for a wide range of applications, providing a total solution.
The new products have a built-in circuit that can drive three phases of high-side and low-side MOSFETs. The gate drive current of external MOSFETs can be set from 10mA to 1A (peak) for the source current and from 20mA to 2A (peak) for the sink current. VM supply voltage can be used in a wide operating range from 8 to 75 V and VDRAIN voltage can be used in a wide operating range from 6 to 75 V. This allows for a wide range of applications such as power tools, cleaners, and industrial robots. In addition, the maximum power supply current (Standby) is 1 μA, thereby providing low current consumption and extending standby time for battery-driven applications. Furthermore, built-in various protection functions improve the reliability of the system. In addition to the protection functions such as the under voltage lockout and the thermal shutdown circuit for the devices themselves, the new products have the gate drive voltage fault detection and overcurrent detection to protect external MOSFETs.
The four new products "TB67Z833SFTG, TB67Z833HFTG, TB67Z853SFTG, and TB67Z853HFTG" have built-in three channels of current sense amplifiers which can lead to saving space on the board by reducing external components.
There are also four products “TB67Z830SFTG, TB67Z830HFTG, TB67Z850SFTG, and TB67Z850HFTG" without current sense amplifiers to meet other application requirements.
Toshiba will continue to develop products for a wide range of applications and to provide total solutions that contribute to design simplification, board area reduction and total cost reduction.
