Automotive-grade galvanic isolation for control and sensor interfaces
It provides 2500Vrms galvanic isolation with a 1Mbps data rate, targeting automotive and industrial applications where signal integrity across a safety barrier is required.
The 2500Vrms isolation rating meets basic reinforced isolation requirements for many automotive and industrial power systems. The 25kV/µs common-mode transient immunity (CMTI) is the spec that matters in motor-drive and inverter designs: fast-switching SiC or IGBT stages can inject several kV/µs across the isolation barrier, and this part holds its data integrity through that edge rate. The 1Mbps data rate is adequate for most sensor readback, fault flags, and low-speed control signals — not for high-throughput video or gigabit links.
Propagation delay and pulse-width distortion — timing budget considerations
Maximum propagation delay is 50ns in both directions, with a pulse-width distortion of 5ns max. For a 1Mbps signal (1µs period), the 50ns delay consumes 5% of the bit period — acceptable for most control loops but worth budgeting in a daisy-chained SPI or time-critical fault path. Rise and fall times are 2.5ns typical, which keeps edge-rate-induced ringing manageable on short PCB traces.
Package and supply — 8-SOIC, 3V to 5.5V rails
Housed in an 8-SOIC (0.154" width) with surface-mount footprint. Supply range from 3V to 5.5V on each side, allowing direct interface with 3.3V or 5V logic domains without an external level translator. No isolated power output — this is a signal-only isolator; the secondary-side Vdd must be supplied separately.
This part is suitable for qualification into production BOMs without near-term supply risk.
