Distributed System Interface (DSI) Sensor Interface
The 33793 is a slave Distributed System Interface (DSI) device that is optimized as a sensor interface. The device contains circuits to power sensors such as accelerometers and to digitize the analog level from the sensor. The device is controlled by commands over the DSI bus and returns measured data over the bus. Features Conforms to DSI Specification Version 1 4-Channel, 8-Bit Analog-to-Digital Converter (ADC) 4 Pins Configurable as Analog or Logic Inputs or as Logic Outputs Provides Regulated +5.0 V Output for Sensor Power from Bus Additional High-Drive Logic Output Undervoltage Fault Detection and Signaling On-Board Clock (No External Elements Required) Field-Programmable Address Default and Field-Programmable as a DSI Daisy Chain Device Recognizes Reverse Initialization for Open Bus Fault Tolerance Detects Short to Battery on Bus Switch and Prevents Its Closure Pb-Free Packaging Designated by Suffix Code EF
