Quick Detail:
Dual Channel Constant Current Control Solenoid Driver
Description:
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 Ω 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 overcurrent, overvoltage and overtemperature conditions, and is able to diagnose and report open loads, shorted loads, and loads shorted to ground.
Note:An external free-wheeling diode must be provided when using the TLE 7241E in constant current control mode, otherwise the IC will be damaged.
For best accuracy, an external 2.5 V reference voltage should be supplied at the REF pin. The TLE 7241E also includes an internal 2.5 V reference voltage, which can be selected by connecting the REF pin to ground. The reference voltage selection (internal or external) can be verified via the SPI interface.
Applications:
•Two Fully Independent Channels
•Integrated N-channel DMOS transistors
•Programmable Average Current with 10-bit resolution via SPI
–Iavg range = 0 to 1000 mA (typical)
•Programmable Superimposed Dither
–Programmable Frequency (41 Hz to 1 kHz typ)
–Programmable Amplitude (12.5 to 390 mVpp typ)
–Programmable Hysteresis (40 to 110 mVpp typ)
•Interface and Control
–16-bit SPI (Serial Peripheral Interface) daisy chainable
–A single “Default” pin to disable both channels and reset the programmable registers of both channels
–5.0 V and 3.3 V logic compatible I/O
–The contents of all registers can be verified via SPI
–Operation with or without external reference possible
•Protection
–Overcurrent
–Overvoltage
–Overtemperature
•Diagnostics
–Overcurrent / shorted solenoid
–Overtemperature
–Open load
–Short to GND
•Green Product (RoHS compliant)
•AEC Qualified
