Infineon TLE8209-2SA

The TLE8209-2  is a SPI programmable H-bridge, designed for the control of DC motors in safety critical automotive applications. It features four selectable current ranges, two selectable slew rate settings and extensive diagnosis via SPI. The device monitors the digital supply voltage V DD and shuts down the output stages in case of V DD over- or undervoltage, thus providing a safe switch off path in case of malfunction of the digital control circuitry. In order to reduce power dissipation in extreme thermal conditions the current limitation threshold is reduced linearly for junction temperatures over 165°C. A thermal warning bit is set in the SPI. The two half bridges can also be used independently to drive two separate loads like solenoids or unidirectional DC motors.
