TPIC8101 Knock Sensor Interface 1 Features 3 Description . 1 Qualified for Automotive Applications The TPIC8101 is a dual-channel signal processing IC. for detection of premature detonation in combustion AEC-Q100 Qualified With the Following Results: engine. The two Sensor channels are selectable Device Temperature Grade 1: 40 C to 125 C through the SPI bus. The Knock Sensor typically Ambient Operating Temperature Range provides an electrical signal to the amplifier inputs. Device HBM Classification Level 3A The sensed signal is processed through a programmable band-pass filter to extract the Device CDM Classification Level C6 frequency of interest (engine Knock or ping signals). Dual-Channel Knock Sensor Interface The band-pass filter eliminates any engine Programmable Input Frequency Prescaler background noise associated with combustion.
