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
• 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

Description
This pin provides the common return for power and signalling.
This pin can be used to provide a logic level output, a logic input, or an analog-to-digital (A/D) input.
This pin is the low reference level and power return for the analog-to-digital converter (ADC).
This pin can be used to provide a logic level output, a logic input, or an A/D input.
This pin can be used to provide a logic level output, a logic input, or an A/D input.
These pins have no internal connections.
This pin can be used to provide a logic level output, a logic input, or an A/D input.
This is a logic output with higher pull-up drive capability than the standard logic I/O.
This pin provides a regulated 5.0 V output. The power is derived from the bus.
A capacitor attached to this pin is charged by the bus during bus idle and supplies current to run the device
and for external devices via the REGOUT pin during non-idle periods.
This pin attaches to the bus and responds to initialization commands.
This pin attaches to the bus and responds to reverse initialization commands.
