Photocoupler reduces mounting area by 50%

Toshiba's new photocoupler, the TLP152, is designed to reduce pcb space and power consumption in igbt and mosfet designs that need galvanic isolation.

The module works by directly driving igbts and mosfets without the need for additional components.

Target applications include factory automation equipment, motor drives, digital home appliances and photovoltaic power micro inverters.

A miniature S06 package is said to reduce mounting area by 50% compared to SDIP packaged devices.

In addition, by lowering minimum supply voltage to 10V, Toshiba says the TLP152also helps to reduce power consumption.

The module has a maximum propagation delay of 200ns. Construction is based around a GaAlAs infrared led optically coupled to an integrated high gain, high speed photodetector ic.
