Additional Information


Knock Sensor Interface ICs

The purpose of the TPIC8101 is to recognize premature detonation in a combustion engine. It is a dual channel device that sends an electrical signal to the amplifier inputs. The SPI bus provides access to the 2 sensor channels. A programmable band-pass filter processes the signal to count how often an engine knocks or pings. The volumn of engine background noise is usually low and is filtered out by the band-pass filter allowing the TPIC8108 to determine any predetonation noise.

Features:
Dual-Channel Knock Sensor Interface
Programmable Input Frequency Prescaler (OSCIN)
Serial Interface With Microprocessor (SPI)
Programmable Gain
Programmable Band-Pass Filter Center Frequency
Programmable Integrator Time Constants
Operating Temperature Range −40C to 125C

Recommended Operating Conditions:
Regulated input voltage: -0.3V min. ; 5.5V max.
Output voltage: -0.3V min. ; 5.5V max.
Input voltage: 0.05Vmin. ; VDD − 0.05V max.
DC input current on terminals CH1P,CH1N,CH2P,and CH2N: −1A min. ; 1μA max.
DC input voltage on terminals CH1P,CH1N,CH2P,and CH2N: Vref,(VDD/2) V max.
Continuous power dissipation: 100 mW max. z

Applications:
Engine Knock Detector Signal Processing
Analog Signal Processing With Filter Characteristics
