Low-power photocoupler delivers enhanced isolation for IPM motor control in high-noise environments
Combining guaranteed operation at temperatures from -40 to 125°C with a minimum input-to-output isolation voltage of 5000 Vrms (AC, 1 min), the TLP754 is ideal for motor control and inverter applications designed for noisy, extended temperature industrial environments.
The TLP754 is supplied in a DIP8 package measuring just 9.6 x 7.6 x 3.6 mm. A wide supply voltage of -0.5 V to 30 V and a wide output voltage of 4.5 V to 30 V enhance design flexibility, while a maximum input current of 1.3 mA meets requirements for high-efficiency designs. Data rates of 1 Mbps are guaranteed thanks to a maximum propagation delay time and pulse width distortion rating of 550 ns and 400 ns 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.
