Description

The TPIC8101DW is a Knock Sensor Interface 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 analogue signal, passed through an output buffer or be read directly by the SPI. This analogue buffered output may be interfaced to an A/D converter and read by the microprocessor.
Dual-channel knock sensor interface
Programmable input frequency prescaler (OSCIN)
Serial interface with microprocessor (SPI)
Programmable gain
Programmable band-pass filter centre frequency
External clock frequencies up to 24MHz (4, 5, 6, 8, 10, 12, 16, 20 and 24MHz)
Programmable integrator time constants
Green product and no Sb/Br
This device has limited built-in ESD protection, leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates.
