Description
The HIP9011 is used to provide a method of detecting
premature detonation often referred to as “Knock or Ping” in
internal combustion engines.
The IC is shown in the Simplified Block Diagram. The chip
can select between one of two sensors, if needed for
accurate monitoring or for “V” type engines. Internal control
via the SPI bus is fast enough to switch sensors between
each firing cycle. A programmable bandpass filter
processes the signal from either of the sensor inputs. The
bandpass filter can be selected to optimize the extraction
the engine knock or ping signals from the engine
background noise. Further single processing is obtained by
full wave rectification of the filtered signal and applying it to
an integrator whose output voltage level is proportional to
the knock signal amplitude. The chip is under
microprocessor control via a SPI interface bus.
