Said to be the first single-channel optocoupler with a transistor output, housed in a BGA (ball grid array) package, is available from Fairchild Semiconductor. The FODB100 microcoupler is designed for consumer electronics, such as chargers, adapters, set-top boxes and appliances, as well as for industrial applications, such as power supplies and motor controls.
The FODB100 device measures 3,5 x 3,5 mm and has a low 1,2 mm profile. With its wide operating temperature range (-40 to +125°C) it can meet the demanding requirements of consumer and industrial products. The single-channel optocoupler consists of an aluminium gallium arsenide infrared light emitting diode driving a silicon phototransistor. Featuring high isolation (2500 V rms for 1 s) and high current transfer ratio at low input current levels, the microcoupler is designed for conventional voltage isolation in power system feedback circuits and for isolating signals in high-voltage, electrically noisy environments.
