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
