Renesas Electronics Corporation Sensor and Detector Interfaces HIP9011ABZ

The HIP9011ABZ is an engine knock signal processor designed to detect premature detonation, commonly known as "knock" or "ping," in internal combustion engines. It features two sensor inputs, allowing for accurate monitoring and flexibility in engine configurations. The device utilizes a programmable bandpass filter to optimize the extraction of knock signals from engine noise, and it includes full wave rectification and integration to provide a voltage output proportional to the knock signal amplitude. Controlled via a microprocessor through an SPI interface, the HIP9011ABZ supports fast sensor switching and programmable characteristics, including gain, filter settings, and time constants. It operates over a temperature range of -40¬8C to 125¬8C and is available in a 20-lead SOIC package, compliant with RoHS standards. This product is suitable for applications requiring precise analog signal processing and engine knock detection.
