Toshiba Electronic Components and Storage Device Corporation (referred to as "Toshiba") has announced the release of new motor driver integrated circuits (ICs) for the consumer products and industrial equipment sectors. The newly introduced ICs, namely "TB67S581FNG," "TB67S580FNG," "TB67H481FNG," and "TB67H480FNG," offer reduced external component requirements and are packaged in a highly versatile and compact form factor.
The TB67S581FNG and TB67S580FNG ICs are designed as 2-phase bipolar stepper motor driver ICs. The TB67S581FNG provides a motor output rated voltage (absolute maximum) of 50V and a motor output rated current (absolute maximum) of 2.5A. Similarly, the TB67S580FNG offers a motor output rated voltage (absolute maximum) of 50V and a motor output rated current (absolute maximum) of 1.6A.
Additionally, the TB67H481FNG and TB67H480FNG ICs belong to the constant current dual H-bridge driver category. These ICs provide a motor output rated voltage (absolute maximum) of 50V and a motor output rated current (absolute maximum) of 2.5A. The TB67H481FNG adopts an IN input interface, while the TB67H480FNG utilizes a PHASE input interface.
These recently launched products feature a highly versatile small HTSSOP28 package, which occupies approximately 39% less space on the circuit board compared to Toshiba's current product, the TB67S109AFNG, which utilizes the larger HTSSOP48 package. Unlike the QFN package with terminals arranged around the perimeter, the HTSSOP package arranges terminals in two directions, facilitating convenient circuit board layout. Furthermore, these ICs internally integrate capacitors for charge pump circuits, effectively reducing the number of external components required and conserving valuable circuit board space.
The motor driver ICs support a wide range of motor power supply voltages, from 8.2V to 44V. Additionally, they offer a highly efficient low power consumption mode (IM1) with a maximum current of 20μA during sleep mode. Consequently, these ICs find application in various power supply scenarios.
Toshiba remains committed to ongoing product development with a focus on versatility, providing comprehensive solutions aimed at simplifying designs, reducing circuit board footprint, and optimizing costs.
