This file contains comprehensive register definitions, bit field masks, and helper structures for the TLE92466ED Six-Channel Low-Side Solenoid Driver IC. All register addresses and bit positions have been meticulously cross-referenced with the official Infineon datasheet (Rev. 1.2, 2022-02-01).

The TLE92466ED features:

  • 6 independent low-side solenoid drivers
  • Integrated Current Control (ICC) with 15-bit resolution (0-2A, 0-4A in parallel)
  • 32-bit SPI interface with 8-bit CRC (SAE J1850)
  • PWM current control with configurable frequency
  • Dither support for precise current shaping
  • Channel parallel operation (0/3, 1/2, 4/5)
  • Comprehensive diagnostics and protection
  • SPI and Clock watchdogs
Device Type:
Low-side solenoid/inductive load driver with current sensing and regulation
SPI Communication:
  • 32-bit frames (8-bit CRC + 7-bit Address + 1-bit R/W + 16-bit Data)
  • CRC: SAE J1850 8-bit polynomial
  • Max frequency: 10 MHz
  • Mode 0 (CPOL=0, CPHA=0)
