The Infineon TLE92466ED is a flexible, monolithic solenoid driver IC designed for the control of linear solenoids in automatic transmissions, electronic stability control and active suspension applications. The device includes the drive transistors and the current sensing resistors to minimize the number of external components. The device controls the load current with less than 1% error. Target currents from 0 to 1500mA can be programmed with a resolution of 15 bit. The device supports dither currents up to 1800mA. The dither generator superimposes a triangular or trapezoidal waveform with programmable amplitude, frequency and shape on the programmed current set point. A 32 bit SPI interface is used to control the 6 channels and monitor the status of the diagnostic functions. The SPI communication is secured with an 8 bit CRC and a programmable timeout watchdog.

Two independent current feedback paths with fast measurement option
Integrated system clock with clock watchdog
Temperature range -40°C to 175 °C
Excellent immunity to large load supply voltage changes
