MC33790DW

Sensor And Detector Interfaces Overview

The MC33790DW is a dual-channel physical layer interface IC for the Distributed System Interface (DSI) bus, designed to meet automotive requirements. It supports bidirectional communication between master and slave ICs using SMARTMOS technology. The device operates with a logic supply voltage of 4.75 V to 5.25 V and a bus supply voltage ranging from 8.0 V to 25.0 V. It features independent thermal shutdown and current limit protection for each channel. The maximum communications rate supported is 150 kbps, with an ESD capability of 2.0 kV. The component is housed in a 16-pin SOICW package.

Sensor And Detector Interfaces Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm lead-free status and package variations. Ensure the selected variant matches the required operating temperature range and packaging specifications for your design implementation.

Sensor And Detector Interfaces Selection Notes

Select this component when a robust physical layer interface for DSI bus communication is required in automotive or industrial environments. Consider the dual-channel architecture if multiple isolated DSI lines are needed within a single footprint. Validate that the VSUP idle level supply meets the system's voltage requirements.

Sensor And Detector Interfaces Part Context

This device serves as a critical interface between standard logic levels and the high-voltage/current requirements of the DSI bus. It enables reliable data transmission in distributed sensor networks by handling signal shaping and return data detection without forming the bus timing itself.

Sensor And Detector Interfaces Replacement Considerations

Check for the MC33790HEG/R2 variant which shares the same core functionality but may differ in package type or manufacturing revision. Verify pinout compatibility before substitution.
