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.

The TLE 5205-2 is an integrated power H-bridge with DMOS output stages for driving DC-Motors. The part is built using the Infineon multi-technology process SPT® which allows bipolar and CMOS control circuitry plus DMOS power devices to exist on the same monolithic structure. Operation modes forward (cw), reverse (ccw), brake and high impedance are invoked from just two control pins with TTL/CMOS compatible levels. The combination of a low R DS ON and the use of a power IC package with low thermal resistance and high thermal capacity helps to minimize system power dissipation. A blocking capacitor at the supply voltage is the only external circuitry due to the integrated freewheeling diodes.
