 3 Channel High-Side and Low-Side Linear Solenoid Driver IC

The TLE82453-3SA is a flexible, monolithic solenoid driver IC designed for the control of linear solenoids i automatic transmission, electronic stability control, and active suspension applications. The three channels can be used as either lowside or highside 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 11 bits resolution. A triangular dither waveform generator, when enabled, superimposes a triangular waveform with programmable amplitude and frequency on the programmed current setpoint.
