Toshiba’s DIP8 Photocoupler Delivers Enhanced Isolation for IPM Motor Control in High-Noise, High-Temperature Environments

The TLP754 is supplied in a DIP8 package measuring just 9.6 x 7.6 x 3.6mm. A wide supply voltage of -0.5V to 30V and a wide output voltage of 4.5V to 30V enhance design flexibility, while a maximum input current of just 1.3mA meets requirements for high-efficiency designs. Data rates of 1Mbps are guaranteed thanks to a maximum propagation delay time and pulse width distortion rating of 550ns and 400ns respectively.

Toshiba’s new device is built around a long-life GaAlAs infrared LED that is optically coupled to an integrated, high-gain, high-speed photodetector IC. The photocoupler has an inverter logic open collector output. An internal Faraday noise shield ensures a guaranteed common mode transient immunity of +/- 20kV/μs.
