Low power, high-speed IC-photocoupler

Toshiba has launched a photocoupler that is claimed to combine communication at 15Mbit/s with low power consumption. The TLP2761 has been designed for use in applications such as inverters, servo amplifiers, photovoltaic inverters, FA networks and I/O interfaces.

The TLP2761 consists of a high-output LED, coupled with integrated high-speed, high gain photodetectors housed in a SO6L package that measures 2.3mm high, approximately 45% slimmer than conventional SDIP package products. Despite the low height, the photocoupler is said to give a creepage and clearance distance of 8mm, and an isolation voltage of 5000Vrms, making it suitable for applications requiring higher isolation specs.

The photocoupler integrates a photo detector IC die in the output side, fabricated using a BiCMOS process, This is said to reduce the supply current by approximately 66% compared to the previous offering, the TLP2766. It supports a threshold input current of 1.6mA and supply current of 1mA, while operating from a supply voltage in the range from 2.7 to 5.5V in temperatures of up to 125°C.
