The Infineon is a high accuracy flexible, monolithic four channel solenoid driver IC designed for the control of four linear solenoids in automatic transmission, electronic stability control, and active suspension applications, it supports dither currents up to 1800mA and the dither generator superimposes a triangular or trapezoidal waveform with programmable amplitude and frequency on the programmed current setpoint, also the device includes the drive transistors and the current sensing resistors to minimize the number of external component. High current control accuracy <±3 mA up to 1200 mA initially, <±0.8% up to 1200 mA including aging
