Photocouplers enable 5Mb/s communication from 6.78mW

 

Featuring a power consumption of just 6.78mW (54% lower than a conventional product, such as the TLP2355), Toshiba Electronics Europe has launched two photocouplers for 5Mb/s communication applications.

The TLP2310 and TLP2710 have both been certified to UL1577 and EN60747-5-5 standards, making them suited for applications requiring high insulation performance, such as AC drives, servo amplifiers, I/O interface boards, photovoltaic devices and factory automation equipment.

The TLP2310 and TLP2710 integrate a very reliable, high output power infrared LED that delivers excellent lifetime characteristics and reduces the threshold input current by about 38% compared to a conventional product. By mounting a light receiving IC that uses a Bi-CMOS process in the output side, each of the photocouplers has a maximum supply current of 0.3mA, which is about 90% lower compared with the conventional product. By sustaining the maximum threshold input current at 1mA, they support bufferless direct drive by a microcomputer and help reduce power consumption and the cost of equipment systems.

Both photocouplers support operate up to a maximum temperature of +125°C and from a power supply voltage range between 2.7 and 5.5V. This contributes to lowering the voltage of devices that use these products.

Housed in packages with a maximum height of 2.3mm, the TLP2310 is available in a 5-pin SO6 package with a minimum clearance and creepage distance of 5mm and minimum isolation voltage of 3.75kVrms. The TLP2710 is housed in a SO6L package, with a minimum clearance and creepage distance of 8mm and a minimum isolation voltage of 5kVrms.
