TLE92464EDXUMA1

TLE92464EDXUMA1 is a flexible, monolithic solenoid driver IC designed for the control of linear solenoids in automatic transmissions, electronic stability control, and active suspension applications. This device includes the drive transistors and the current sensing resistors to minimize the number of external components. This device controls the load current with less than 1% error. Target currents from 0 to 1500mA can be programmed with a resolution of 15 bits. 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 setpoint. Potential applications include variable force solenoids (e.g. automatic transmission and e-Axle), other constant current solenoids, idle air control, exhaust gas recirculation, vapor management valve, and suspension control.
