Toshiba Electronics Europe TB67S581FNG and TB67S580FNG

Toshiba's TB67S581FNG and the TB67S580FNG are two-phase bipolar stepping motor drivers. Both devices feature a motor output voltage rating up to 50V, with the TB67S581FNG having an output current rating up to 2.5A and the TB67S580FNG being rated up to 1.6A. Both devices have built-in charge pump capacitors.

They are housed in HTSSOP28 packages and are drop-in compatible with popular competing devices. The mounting area of this package is approximately 39% smaller compared to the previous generation.

The TB67S581FNG/580FNG do not require external components for the integrated charge pump.

Key features

• Drop-in compatible with popular competing devices
• No external capacitor needed for integrated charge pump
