Product details

6000Vrms isolation in a 10-channel SPI isolator

It handles SPI clock, data, and chip-select lines with a data rate up to 100Mbps, making it a fit for high-speed sensor interfaces, isolated ADC links, and motor-drive feedback paths where reinforced insulation is required. The 50kV/µs common-mode transient immunity keeps data intact when fast-switching power stages slam the barrier with noise — a spec that matters more than the headline isolation voltage in inverter and servo-drive applications.

Supply range and channel configuration

The supply range spans 3V to 5.5V on both sides, so it runs from a single 3.3V or 5V rail without a level translator. There are 7 inputs on side 1 and 6 on side 2, with a mix of bidirectional and unidirectional channels to handle the SPI bus handshake. Propagation delay is 150ns max in either direction, which sets the timing budget for the SPI clock period — at 100Mbps the 10ns rise/fall times eat into the bit time, so keep the trace lengths short and the bus loading light.

Package and temperature grade

Housed in a 36-BGA (15x6.25mm) package, this is a surface-mount part that needs a reflow profile, not a socket swap in the field. No isolated power is integrated, meaning the secondary side needs its own isolated supply rail or an external DC/DC module.

Frequently asked questions

What is the data rate of LTM2893HY-1#PBF?

The LTM2893HY-1#PBF supports a data rate up to 100Mbps, which is the maximum SPI clock speed it can pass across the isolation barrier. At that rate, the 10ns rise and fall times and 150ns propagation delay need to be factored into the bus timing budget.

Does LTM2893HY-1#PBF require isolated power on the secondary side?

Yes, this part does not include an integrated isolated power supply. The secondary side of the isolation barrier needs its own isolated power rail, either from a separate isolated DC/DC converter or from an existing isolated supply in the system.
