Characteristics  
description  
The TPIC8101 is a dual-channel signal processing IC for detection of premature detonation in combustion  
engine. The two sensor channels are selectable through the SPI bus. The knock sensor typically provides an  
electrical signal to the amplifier inputs. The sensed signal is processed through a programmable band-pass filter  
to extract the frequency of interest (engine knock or ping signals). The band-pass filter eliminates any engine  
background noise associated with combustion. The engine background noise is typically low in amplitude  
compared to the predetonation noise.  
The detected signal is full-wave rectified and integrated by use of the INT/HOLD signal. The digital output from  
the integration stage is either converted to an analog signal, passed through an output buffer, or be read directly  
by the SPI.  
This analog buffered output may be interfaced to an A/D converter and read by the microprocessor. The digital  
output may be directly interfaced to the microprocessor.  
The data from the A/D enables the system to analyze the amount of retard timing for the next spark ignition timing  
cycle.  
With the microprocessor closed-loop system, advancing and retarding the spark timing optimize the load/RPM  
conditions for a particular engine (data stored in RAM).  
Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of  
Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.
