Feedback to microcontrollers in factory automation equipment relies on accurate monitoring of the phase current of motors and BUS voltage fluctuations, to achieve high-precision operation. To meet these requirements, the company has equipped the TLP7830 and TLP7930 with a delta sigma ADC at the input side that enables them to achieve a high level of linearity of 4 LSB (typical) at intergrity non linearity.

The two devices provide a guaranteed common mode transient immunity of 20kV/µs (typical at VCM=1kV, Ta=25˚C). This enables stable operation in an electrically noisy environment, making them suitable for motor control applications. The optical barrier guarantees an isolation voltage of 5000Vrms (minimum). Operating temperature is -40 to 105˚C.

Two package types are available: TLP7930 is supplied in an industry-standard DIP8 package and the TLP7830 is available in a new, compact SO8L package, which takes up 30% less board space and features a 40% lower profile, says the company.
