FN4367.2

Engine Knock Signal Processor

The HIP9011 is used to provide a method of detecting

premature detonation often referred to as “Knock or Ping” in

internal combustion engines.

Features

• Two Sensor Inputs

• Microprocessor Programmable

• Accurate and Stable Filter Elements

• Digitally Programmable Gain

• Digitally Programmable Time Constants

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

• Digitally Programmable Filter Characteristics

• On-Chip Crystal Oscillator

• Programmable Frequency Divider

• External Clock Frequencies up to 24MHz

- 4, 5, 6, 8, 10, 12, 16, 20, and 24MHz

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

• Operating Temperature Range -40 C to 125 C

• Pb-Free Plus Anneal Available (RoHS Compliant)

microprocessor control via a SPI interface bus.

NOTE: Intersil Pb-free plus anneal products employ special Pb-free

material sets; molding compounds/die attach materials and 100%

matte tin plate termination finish, which are RoHS compliant and

compatible with both SnPb and Pb-free soldering operations. Intersil

Pb-free products are MSL classified at Pb-free peak reflow

temperatures that meet or exceed the Pb-free requirements of

IPC/JEDEC J STD-020.
