NSIP9840W1-Q1SWR
NOVOSENSE NSIP9840W1-Q1SWR quad-channel digital isolator with an integrated isolated DC-DC, 5000 Vrms, AEC-Q100 Grade 1, in a SOW16 package.
The NSIP9840W1-Q1SWR is a NOVOSENSE four-channel digital isolator with an integrated isolated DC-DC converter, in a SOW16 package, qualified to AEC-Q100 Grade 1 over -40 °C to +125 °C. It combines a high-reliability quad-channel digital isolator with an isolated DC-DC converter that provides up to about 500 mW of output power using an on-chip transformer, so a single device carries both the signals and the isolated power across the barrier. The power stage supports 5 V to 5 V and 5 V to 3.3 V with up to 100 mA of load current, and 3.3 V to 3.3 V with about 60 mA, with over-current and over-temperature protection, and the digital isolator supports a data rate up to 150 Mbps with a high common-mode transient immunity of about 100 kV/us. The signal channels can be mixed in direction by part number, so the part fits an isolated interface that also needs its own isolated supply, which removes a separate isolated power module and saves the board area. Typical applications include an isolated CAN or SPI interface with isolated power, an automotive or industrial isolated control and any design that must cross a barrier with power and data. Availability is confirmed per project. Every device BeiLuo ships is factory-traceable and includes an import declaration, a certificate of origin and a RoHS compliance file.
FAE Professional Review
The NSIP9840W1-Q1SWR is the part to choose when the isolated side needs its own power, because the integrated isolated DC-DC carries up to about 500 mW across the same barrier as the four signal channels, which removes a separate isolated supply. The AEC-Q100 Grade 1 rating suits an under-hood design. Plan the isolated supply and the decoupling and confirm the load current for the configuration.
