TPIC8101SLIS110C –APRIL 2003–REVISED MARCH 2015
TPIC8101 Knock Sensor Interface Features 3 DescriptionThe TPIC8101isa dual-channel signal processingIC Qualifiedfor Automotive Applications for detectionof premature detonationin combustion• AEC-Q100 Qualified With the Following Results: engine. The two sensor channels are selectable Device Temperature Grade1: –40°Cto 125°C through the SPI bus. The knock sensor typically
Ambient Operating Temperature Range provides an electrical signalto the amplifier inputs.
The sensed signal is processed through a– Device HBM Classification Level 3A programmable band-pass filter to extract the– Device CDM Classification Level C6 frequencyof interest (engine knockor ping signals). Dual-Channel Knock Sensor Interface The band-pass filter eliminates any engine
background noise associated with combustion. The• Programmable Input Frequency Prescaler engine background noiseis typically lowin amplitude(OSCIN) comparedto the predetonation noise.• Serial Interface With Microprocessor (SPI)
The detected signal is full-wave rectified and• Programmable Gain integratedby useof the INT/HOLD signal. The digital• Programmable Band-Pass Filter Center output from the integration stageis either convertedFrequency toan analog signal, passed through an output buffer, External Clock Frequenciesupto24 MHz or be read directlyby the SPI. 4,5,6,8, 10, 12, 16, 20, and24 MHz This analog buffered output may be interfacedto an
A/D converter and read by the microprocessor. The• Programmable Integrator Time Constants
digital output may be directly interfaced to the• Operating Temperature Range −40°Cto 125°C microprocessor.
