Description

TI reference design TIDA-00322 is an automotive liquid level and fluid identification measurement system. It is based on the dual-channel TDC1000-Q1 ultrasonic AFE and the real-time microcontroller C2000. This reference design can also be used with the TDC1000 for industrial/consumer applications. This solution supports 4.5-40V system capabilities with reverse battery protection. For prototyping and signal accessibility for product development: TI recommends using the TDC1000-C2000EVM as the hardware evaluation platform for automotive designs. For industrial or consumer designs: it is recommended to begin evaluation with the TDC1000-TDC7200EVM. This EVM has the ability of using the MSP430 or the TDC7200 as the stop-watch timer; usage of each depends on the time of flight accuracy requirement of the application.
