Two-channel isolator with on-chip isolated power
The ADUM6202CRWZ from Analog Devices combines two unidirectional digital isolation channels with an integrated IsoPower DC-DC converter in a single 16-SOIC package. Rated for 5000 Vrms isolation and 25 Mbps data rate, it eliminates the separate isolated power module that a standard digital isolator would need on the secondary side. The 2.5 ns typical rise/fall time and 60 ns max propagation delay keep timing margins tight for SPI and UART isolation up to 25 Mbps.
25 kV/µs CMTI — why it matters for motor drives and inverters
Common-mode transient immunity of 25 kV/µs minimum means this isolator holds its logic state through the fast voltage swings on the switching node of a motor drive or power inverter. If the CMTI is too low, the isolator's output can glitch, corrupting the gate-drive or feedback signal. At 25 kV/µs the ADUM6202CRWZ handles the edge rates found in IGBT and SiC gate-drive circuits without extra filtering.
Supply range and channel direction
The 0/2 input-side-to-output-side count means both channels run from Side 2 to Side 1 — all outputs are on the primary side. For designs needing mixed-direction channels, the ADUM6400CRWZ (4-channel, 4/0) or ADUM5402CRWZ (4-channel, 2/2) offer different direction splits.
Package and assembly notes
Housed in a 16-lead SOIC with 7.50 mm body width — the wide-body SOIC-16 footprint. The IsoPower DC-DC converter runs at a switching frequency that can couple into sensitive analog traces, so keep the secondary-side output capacitor close to the device and avoid routing the isolated power plane under the primary-side circuitry.
