The TLE 5205-2 is an integrated power H-bridge with DMOS output stages for driving DC-Motors. The part isbuilt 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 an extremely low RDS 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.
