Version

2.0.0

Comprehensive C++23 driver for the Infineon TLE92466ED IC. This driver provides a complete, feature-rich interface to all capabilities of the IC including:

Core Features:

• 6 independent low-side solenoid output channels
• Integrated Current Control (ICC) with 15-bit resolution
• Current range: 0-2A register scale (1.5A typical continuous) single channel 0-4A register scale (2.7A typical continuous) parallel mode
• 32-bit SPI with CRC-8 (SAE J1850)
• Hardware-agnostic design via polymorphic HAL

Current Control Features:

• Precision current regulation (15-bit resolution = 0.061mA steps)
• PWM frequency control for current regulation
• Integrator-based current controller
• Dither support (configurable amplitude and frequency)
• Load current feedback and monitoring

Channel Operation Modes:

• ICC Mode: Integrated Current Control with precise regulation
• Direct Drive: SPI-controlled on-time
• External Drive: DRV0/DRV1 pin-controlled
• Free-running Measurement: Continuous current sensing

Parallel Operation:

• Channels can be paired: 0/3, 1/2, 4/5
• Doubles current capability (up to 4A)

Protection & Diagnostics:

• Open-load detection (ON and OFF states)
• Short-to-ground detection
• Over-current protection
• Over-temperature (warning and shutdown)
• Under/over-voltage monitoring (VBAT, VIO, VDD)
• SPI watchdog
• Clock watchdog
• CRC error detection

Usage Example:

MyPlatformHAL hal;
TLE92466ED::Driver driver(hal);
 
// Initialize
driver.init();
driver.enter_mission_mode();
 
// Configure channel 0 for 1.5A current control
driver.set_channel_mode(Channel::CH0, ChannelMode::ICC);
driver.set_current_setpoint(Channel::CH0, 1500); // 1500 mA
 
// Enable channel
driver.enable_channel(Channel::CH0, true);
 
// Monitor
auto current = driver.get_average_current(Channel::CH0);
auto status = driver.get_channel_diagnostics(Channel::CH0);
