Wide output voltage, high-speed coupler offers minimum isolation voltage of 5000Vrms
Toshiba Electronics Europe (TEE) has released an ultra-miniature IC photocoupler* that will meet the needs of high component density industrial IPM drive applications required to operate across extended temperatures.
Offering guaranteed operation at temperatures from -40°C to 125°C, the TLP714 is supplied in a compact SDIP6 package with a PCB footprint of just 9.7mm x 4.58mm. Board mounting profile is only 4.0mm. A wide output voltage range of 4.5V to 30V and a data transmission speed of 1Mbps make the device ideal for a wide variety of motor control, servo control and industrial automation applications requiring isolation between IPM and control IC circuitry.
Despite a board mounting area of around half that of equivalent DIP8 devices, the TLP714 complies with the reinforced insulation class of international safety standards. Minimum isolation voltage is rated at 5000Vrms, while an internal noise shield ensures minimum common mode transient immunity of ±20kV/?s.
Toshiba’s new photocoupler is based on a GaAlAs infrared LED that is optically coupled to an integrated, high-gain, high-speed photodetector IC. The device features an inverter logic type open collector output and will operate with supply voltages from -0.5V to 30V. Maximum threshold input current is 5.0mA and maximum supply current is rated at 1.3mA.
