Rhopoint is new source for digital isolators

Following the Company’s appointment by NVE Corporation to be its exclusive agent for Scandinavia, a new range of fully monolithic 40Mbps magnetic digital isolators is now available ex-stock from Rhopoint Components. With their low power dissipation of 4mA, they may be used to replace opto-couplers in isolation functions, in CAN bus/Device Net and I2C applications, or as isolated RS422 receivers, isolated relay drivers and isolated wired-or alarms. They are failsafe and dc-stable but, unlike opto-couplers, have no intrinsic wear-out mechanism.

With floating coil input, the isolators are simple to interface with any input voltage from 0.5V to 400V, through a current limiting resistor. Data rates of 40Mbps, and 7ns pulse width distortions, are achievable.

While available in a single die package for easy mounting on hybrids, an MSOP package option makes this range of isolators one of the smallest. They offer isolation of up to 2500Vr.m.s. in PDIP and SOIC packages, and 1000Vr.m.s. in the MSOP package.

Magnetic digital isolators to replace opto couplers

Optional output configurations are CMOS and open-drain for wire-or connection. Approval to UL1577 and IEC061010 is pending.
