Toshiba Electronic Devices & Storage Corporation has announced the launch of motor driver ICs that offer space-saving solutions for consumer and industrial equipment. These innovative ICs require fewer external parts and come in a compact package, providing versatility and efficiency. With the introduction of four new products—TB67S581FNG, TB67S580FNG, TB67H481FNG, and TB67H480FNG—Toshiba aims to expand its lineup and cater to various market needs. Shipments of these motor driver ICs have already begun.
The TB67S581FNG and TB67S580FNG are two-phase bipolar stepping motor driver ICs. The former has a motor output voltage rating of 50V and a motor output current rating of 2.5A, while the latter boasts ratings of 50V and 1.6A respectively. These ICs are designed to efficiently drive two-phase bipolar stepping motors, making them suitable for applications in both consumer and industrial sectors.
On the other hand, the TB67H481FNG and TB67H480FNG are constant current dual H-bridge driver ICs. These ICs have a motor output voltage rating of 50V and a motor output current rating of 2.5A. The TB67H481FNG employs an IN input interface, while the TB67H480FNG uses a PHASE input. These dual H-bridge driver ICs are designed to provide robust motor control capabilities for a wide range of equipment.
The newly introduced ICs employ the HTSSOP28 package, which is highly versatile and significantly smaller than Toshiba’s previous HTSSOP48 package used in the TB67S109AFNG motor driver IC. This package offers a mounting area that is approximately 39% smaller, enabling space-saving benefits on circuit boards. Unlike the QFN type package, the HTSSOP package features terminals arranged in two directions, simplifying the wiring process. Additionally, the ICs incorporate capacitors for charge pump circuits, reducing the need for external components and further optimizing board space.
These motor driver ICs support motor power supply voltages ranging from 8.2V to 44V and have a power consumption of up to 20μA in sleep mode. This wide power supply compatibility and low power consumption make them suitable for various applications utilizing 12V/24V power supplies.
Toshiba remains committed to developing cutting-edge products for diverse applications. By providing comprehensive solutions that streamline design processes, reduce board area requirements, and lower overall costs, Toshiba aims to meet the evolving demands of the market. With the launch of these motor driver ICs, Toshiba continues to drive innovation in the field of electronic devices and storage.
