TLE7241E

The TLE 7241E is a dual channel constant current control solenoid driver with integrated DMOS power transistors. The average load current can be programmed to a value in the range of 0 mA to 1000 mA (with a 1 OHM external sense resistor) with 10 bits of resolution. Load current is controlled using a hysteretic control scheme with a programmable hysteresis value. A triangular “dither” waveform can be superimposed on the switching current waveform in order to improve the transfer function of the solenoid. The amplitude and frequency of the dither waveform are programmable by the SPI interface. The device is protected from damage due to over-current, overvoltage and over-temperature conditions, and is able to diagnose and report open loads, shorted loads, and loads shorted to ground.
