Toshiba Electronics Europe TB67H480FNG and TB67H481FNG

The TB67H481FNG/480FNG are constant-current dual H-bridge drivers, featuring a motor output voltage rating up to 50V and an output current rating up to 2.5A. These ICs can be used to power DC brushed motors or bipolar stepping motors.

The pair offers a choice of input interfaces, with the TB67H481FNG using a pulse-width modulated (PWM) input and the TB67H480FNG using a PHASE/ENABLE input. Both devices feature built-in charge pump capacitors and are drop-in compatible with popular competing devices.

The TB67H481FNG/480FNG 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
• Motor output voltage rating up to 50V / 2.5A
