Toshiba Electronic Devices & Storage Corporation (Toshiba) has announced the release of a series of motor driver ICs designed to meet the requirements of consumer and industrial equipment. These ICs offer a compact form factor, reduced external parts, and high versatility, making them ideal for space-constrained applications. Toshiba’s product lineup expands with the introduction of four new offerings: TB67S581FNG, TB67S580FNG, TB67H481FNG, and TB67H480FNG, all of which are now available for shipment.
Among the newly launched products, TB67S581FNG and TB67S580FNG are two-phase bipolar stepping motor driver ICs. These ICs are specifically designed to control and drive two-phase bipolar stepper motors. TB67S581FNG features a motor output voltage rating of 50V and a motor output current rating of 2.5A, while TB67S580FNG offers ratings of 50V and 1.6A, respectively.
Bipolar stepper motors are widely used in various applications such as robotics, automation, 3D printers, and CNC machines. These motors consist of two coils, each with a center tap, enabling the flow of two phases of current through the coils. By appropriately energizing the coils in a specific sequence, the motor can rotate in precise steps.
The newly introduced two-phase bipolar stepping motor driver ICs play a crucial role in controlling and driving these motors effectively. They provide the necessary electrical signals and power amplification required for accurate motor motion control. These ICs incorporate features like current regulation, step and direction control, microstepping capability, and protection circuits to ensure safe and efficient motor operation.
By integrating the essential control and driver circuitry into a single package, the two-phase bipolar stepping motor driver ICs simplify the design and implementation of stepper motor control systems. They serve as an interface between the motor and a microcontroller or control logic, enabling precise control over the motor’s speed, direction, and positioning.
The remaining two products in the lineup, TB67H481FNG and TB67H480FNG, are constant current dual H-bridge driver ICs. These ICs feature a motor output voltage rating of 50V and a motor output current rating of 2.5A. TB67H481FNG utilizes the IN input interface, while TB67H480FNG employs the PHASE input.
All of the motor driver ICs introduced by Toshiba employ the compact and versatile HTSSOP28 package, which occupies approximately 39% less mounting area compared to the HTSSOP48 package used in Toshiba’s existing TB67S109AFNG product. Unlike the QFN type package, which has terminals arranged in four directions, the HTSSOP package arranges terminals in two directions, simplifying the wiring process on circuit boards. Moreover, these ICs incorporate capacitors for charge pump circuits, reducing the need for external parts and saving valuable space on circuit boards.
The motor driver ICs are compatible with motor power supply voltages ranging from 8.2V to 44V and feature low power consumption of up to 20μA in sleep mode. These characteristics make them suitable for a wide range of 12V/24V power supply applications.
Toshiba remains committed to the development of innovative solutions that contribute to design simplification, board area reduction, and overall cost savings. The company will continue to deliver products that cater to diverse application requirements and provide comprehensive solutions for various industries. With the introduction of these new motor driver ICs, Toshiba aims to enhance equipment performance and meet the evolving needs of its customers.
