Product details

30kV/µs CMTI — why it matters for motor drives and inverters

Common-mode transient immunity (CMTI) of 30kV/µs minimum means this isolator can reject fast voltage spikes that couple across the isolation barrier during IGBT switching or relay contact bounce. In a variable-frequency drive or servo drive, the DC bus can swing hundreds of volts in a few nanoseconds; a low-CMTI isolator would latch or corrupt the SPI data. The 30kV/µs rating here is on par with industrial-grade magnetic isolators and gives enough margin for most 400V-class drive applications. The 3ns typical rise/fall time also helps maintain signal integrity on the BGA's short PCB traces.

Package and integration — 32-BGA (15x11.25mm)

The 32-BGA package measures 15x11.25mm — a compact footprint for an isolator that includes its own isolated power supply. Supply voltage range of 3V to 3.6V means it runs directly from a 3.3V rail without an extra regulator.

For dual-sourcing or a pin-compatible alternate, the ADM3252EABCZ (also with integrated isolated power) is a functional cross-shop candidate — it offers 460Kbps data rate and 2500Vrms isolation, but its channel count is 4 (2/2 split) and it is an RS232 transceiver isolator, not a general-purpose SPI isolator, so the fit depends on the interface type needed.

Frequently asked questions

What is the recommended replacement or equivalent for LTM2883HY-3S#PBF?

There is no direct pin-compatible replacement from the same manufacturer. The ADM3252EABCZ (Analog Devices) is a functional cross-shop candidate with integrated isolated power and 2500Vrms isolation, but it is an RS232 transceiver isolator with 4 channels (2/2 split) and 460Kbps data rate — not a general-purpose SPI isolator. Verify the interface type and channel count before substituting.

Does LTM2883HY-3S#PBF support SPI data rates higher than 400kHz?

No, the guaranteed data rate is 400kHz. The propagation delay (100ns max each way) and rise/fall times (3ns typ) limit throughput. For higher SPI clock rates, consider isolators rated for 10 Mbps or 25 Mbps, but those typically lack integrated power or have different channel counts.

Is LTM2883HY-3S#PBF compatible with 3.3V logic?

Yes, the supply voltage range of 3V to 3.6V covers 3.3V logic directly. The unidirectional channels accept 3.3V CMOS levels on both sides without level shifting.
