数据手册.pdfIC DSI SLAVE FOR R-SENSE 16-SOIC
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 orLogic 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
