Product details

USB isolator with on-board isolated power

This means you get a galvanically isolated USB port without needing a separate isolated power supply: the module generates its own isolated side power from the 4.4 V to 16.5 V input rail. The isolation rating is 2500 Vrms, using magnetic (transformer) coupling, and the data rate is 12 Mbps — full-speed USB 1.1/2.0 compatible. The single bidirectional channel handles USB D+ and D- signals.

Isolation barrier and transient immunity

The magnetic coupling technology delivers a common-mode transient immunity of 30 kV/µs minimum — important for rejecting fast transients in motor-drive or industrial environments where ground potential differences can spike. Propagation delay is 115 ns max in both directions, which is adequate for USB handshake timing at 12 Mbps. Rise and fall times are 20 ns typical (20 ns max), keeping signal edges clean within the USB specification.

Surface-mount only — no through-hole option.

It is ROHS3 compliant (lead-free).

Frequently asked questions

Does LTM2884IY#PBF have isolated power?

Yes, the LTM2884IY#PBF integrates an isolated DC/DC converter, so it generates its own isolated-side power from the input supply — no external isolated power module needed.

What is the closest functional equivalent to LTM2884IY#PBF?

The ADUM3160 also has an automotive-grade variant and a slightly faster propagation delay (70 ns vs 115 ns).
