Infineon Technologies AG Power - Automotive conventional powertrain ICs - Constant Current Control IC for Transmission - TLE92464ED TLE92464ED

The device controls the current through inductive loads with less than 1% error. Target currents can be programmed from 0 to 1500mA with a resolution of 15 bit. The TLE92464ED supports dither currents up to 1800mA. The dither generator superimposes a triangular or trapezoidal waveform with programmable amplitude and frequency on the programmed current setpoint. The device includes the drive transistors and the current sensing resistors to minimize the number of external components. TLE92464ED is ISO 26262 compliant and achieves safety level ASIL C.
