Introduction

The FOD8480 and FOD8482 are low power optocouplers, which support isolated interface to Intelligent Power Module (IPM) communicating digital control signals from the controller to the IPM, without conducting ground loops or hazardous voltages. The FOD848x Series, packaged in a stretched body 6−pin small outline plastic package, consists of an aluminum gallium arsenide (AlGaAs) light emitting diode and an integrated high gain photo detector. The detector has a detector threshold with hysteresis. The hysteresis provides differential mode noise immunity and eliminates the potential for output signal chatter. Its non−inverting output is designed as totem pole, which does not require any pull−up resistor. The FOD8482 has a lower threshold input current, IFLH, at 3.0 mA maximum. For the complete FOD848x Series, the Electrical and Switching Characteristics are guaranteed over the extended industrial temperature range of -40°C to 100°C and a VDD range of 4.5 V to 30 V. Low IF and wide VDD range allow compatibility with TTL, LSTTL, and CMOS logic and result in lower power consumption compared to other high speed optocouplers.
