TLE82453-3SA
The TLE 82453 is a flexible, monolithic solenoid driver IC designed for the control of linear solenoids in automatic transmission, electronic stability control, and active suspension applications. The three channels can be used as either low-side or high-side drivers in any combination. The device includes the drive transistor, recirculation transistor, and current sensing resistor; minimizing the number of required external components. This device is capable of regulating the average current flow in a load up to 1500 mA, depending on the dither settings and the load characteristics, with 0.73 mA resolution. A triangular dither waveform generator, when enabled, superimposes a triangular waveform with programmable amplitude and frequency on the programmed current setpoint
