onsemi FOD848x Optically Isolated IPMs
onsemi FOD848x Optically Isolated Intelligent Power Modules (IPM) communicate digital control signals from the controller to the IPM without conducting ground loops or hazardous voltages. onsemi FOD848x IPMs are packaged in a stretched body 6-pin small outline plastic package consisting of an aluminum gallium arsenide (AlGaAs) light-emitting diode and an integrated high-gain photodetector. The photodetector has a detector threshold with hysteresis that provides differential mode noise immunity and eliminates the potential for output signal chatter. The non-inverting output is designed as a totem pole, which does not require any pull-up resistor. The FOD8482 has a low threshold input current, IFLH, at 3.0mA maximum.
The FOD848x Modules are guaranteed over the extended industrial temperature range of -40°C to +100°C and a VDD range of 4.5V to 30V. The devices offer low IF and wide VDD range that allows compatibility with TTL, LSTTL, and CMOS logic. This results in lower power consumption compared to other high-speed optocouplers.
