描述: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.特征描述:Two Fully Independent ChannelsIntegrated N-channel DMOS transistorsProgrammable Average Current with 10-bit resolution via SPIIavg range = 0 to 1000 mA (typical)Programmable Superimposed DitherProgrammable Frequency (41 Hz to 1 kHz typ.)Programmable Amplitude (12.5 to 390 mVpp typ.)Programmable Hysteresis (40 to 110 mVpp typ.)Interface and Control16-bit SPI (Serial Peripheral Interface) daisy chainableA single “Default” pin to disable both channels and reset the programmable registers of both channels5.0 V and 3.3 V logic compatible I/OThe contents of all registers can be verified via SPIOperation with or without external reference possibleProtectionOver-currentOvervoltageOver temperatureDiagnosticsOver-current / shorted solenoidOver temperatureOpen loadShort to GNDGreen Product (RoHS compliant)AEC Qualified目标应用:Variable force solenoids (e.g. automatic transmission solenoids)Constant current controlled solenoids likeIdle Speed ControlExhaust Gas RecirculationValve controlSuspension Control
