DATASHEET HIP9011 Engine Knock Signal Processor FN4367 Rev 2.00 January 6, 2006 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 f
