Si88643ED-AS

Leveraging a true automotive process for design, manufacturing, production test, and support Si88643ED-AS integrates our proven digital isolator technology with an on-chip dc-dc converter. The integrated dc-dc converter provides isolated, regulated output voltages of 3 or 5.5V (or >5 V with external components) at peak output power levels of up to 2 W. The device provides 1 foward and 3 reverse digital channels and supports data rates up to 100Mbps. Additionally, Si88643ED-AS devices achieve propagation delays of only 23 ns max and are certified by UL, CSA, VDE, and CQC.

Si88XXXLOWEMC-KIT

Si88xxx Low EMC EVB

The Si88xxx Low EMC EVB reference design with the Si88241 utilizes best practices for mitigating emissions and instantiates techniques for passing the very stringent requirements of the CISPR 25 standard. The Si88241 is a digital isolator with an integrated dc-to-dc converter. As with all dc-to-dc converters, conducted and radiated emissions must be carefully studied and controlled. Two MCUs on the primary and secondary sides continuously send SPI data across the isolators. Four channels of bidirectional isolated data transfer with jumper-selectable SPI data rates allow the testing of emissions with actual data traffic.
