This TIDA-00152 reference design utilizes a dual-channel, signal processing IC for detection of premature detonation in combustion (gasoline) engines. The heart of this design is the TPIC8101 that serves as an interface between acoustical sensors or accelerometers and automobile engine management systems. Programmable features on this device include the selection of engine knock detection sensitivity, engine resonance frequency, and sampling rate control of on-board ADC and DAC in signal processing chain. These features allow the TPIC8101 to be a flexible interface that can adapt to cost and/or processing time constraints of the customer.
A fully assembled board has been developed for testing and performance validation only, and is not available for sale.
