High‑pressure fuel pump driver module for motorsport powertrain systems

High-Pressure Fuel Pump Driver

HPF-320 is a compact high‑pressure fuel pump driver with CAN‑controlled current waveform for motorsport use

The HPF‑320 High‑Pressure Fuel Pump Driver is a compact unit designed for motorsport applications to operate alongside a powertrain control unit. It generates a current‑controlled waveform to drive a high‑pressure fuel pump solenoid inlet valve directly from a single TTL trigger pulse, with key waveform parameters defined over CAN. A single‑chip processor configures the drive waveform and gathers diagnostic data, while an FPGA processes external trigger pulses and controls the drive stage. Diagnostic and status information is transmitted over CAN, allowing close integration with the vehicle control system.
