MC33793D

Sensor And Detector Interfaces Overview

The MC33793D is a slave Distributed System Interface (DSI) sensor interface device optimized for remote sensing applications. It digitizes analog levels from sensors such as accelerometers and provides regulated +5.0 V output for sensor power. The device features a 4-channel, 8-bit ADC and four configurable I/O pins that function as analog inputs, logic inputs, or logic outputs. It includes an on-board clock, field-programmable address capability, and undervoltage fault detection. Powered by SMARTMOS technology, it supports DSI specification version 1 and operates within a temperature range of -40°C to 150°C in a 16-pin SOICN package.

Sensor And Detector Interfaces Procurement Notes

Verify the specific ordering suffix against the manufacturer's current catalog to confirm package type and temperature grade. Ensure compatibility with the target DSI bus protocol version. Confirm lead times and availability directly with authorized distributors prior to finalizing design-in decisions.

Sensor And Detector Interfaces Selection Notes

Select this component when a robust, single-chip solution is required for remote sensor interfacing over a DSI bus. Consider the 8-bit ADC resolution and configurable I/O flexibility for diverse sensor types. Evaluate the operating temperature range and package thermal characteristics against the environmental constraints of the intended application.

Sensor And Detector Interfaces Part Context

The MC33793D belongs to the NXP (formerly Freescale) DSI family of sensor interface devices. It is designed to work in conjunction with central microcontrollers to manage remote sensing nodes. The device simplifies system architecture by integrating power regulation, signal conditioning, and digital communication into a single integrated circuit.

Sensor And Detector Interfaces Replacement Considerations

Check for direct pin-compatible alternatives within the same DSI product line. Verify functional equivalence regarding ADC channels, I/O configuration options, and power output capabilities before substituting.
