Toshiba Introduces Small Package Motor Driver IC with Fewer External Parts, Saving Board Space

Toshiba today announced the release of "TB67S581FNG," "TB67S580FNG," "TB67H481FNG," and "TB67H480FNG," motor driver ICs for consumer and industrial Small package for space. With the introduction of 4 new products, Toshiba has further expanded its product line. The product supports volume shipments starting today.

Among them, the two new products, TB67S581FNG and TB67S580FNG, are 2-phase bipolar stepping motor driver ICs. The motor output rated voltage of TB67S581FNG is 50V, the motor output rated current is 2.5A[1], the motor output rated voltage and current of TB67S580FNG are 50V and 1.6A[1] respectively.

The other two products, TB67H481FNG and TB67H480FNG, are constant-current dual H-bridge driver ICs. The rated output voltage of the motor is 50V, and the rated output current of the motor is 2.5A[1]. The input interface of TB67H481FNG is IN input, while TB67H480FNG uses PHASE input.

The four products introduced today are housed in the extremely versatile small HTSSOP28 package, which has approximately 39 percent smaller surface mount area than the HTSSOP48 package used in Toshiba's current product, the TB67S109AFNG. Unlike the QFN type package, which has terminals arranged all around, the HTSSOP package has terminals arranged in two directions, so it is easier to route on the circuit board. These ICs have internally integrated capacitors for the charge pump circuit, which not only reduces external components but also saves board space.

The motor driver IC not only supports motor supply voltage from 8.2V to 44V, but also has a low power consumption current (IM1) of up to 20μA in sleep mode, so it can be widely used in 12V/24V power supply applications.

Toshiba will continue to develop products for a wide range of applications and provide total solutions that help simplify design, reduce board area, and reduce overall cost.
