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 high and brake low 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.

Buffer amplifiers are driven by this stages. Output Stages The output stages consist of a DMOS H-bridge. Integrated circuits protect the outputs against short-circuit to ground and to the supply voltage. Positive and negative voltage spikes, which occur when switching inductive loads, are limited by integrated freewheeling diodes. A monitoring circuit for each output transistor detects whether the particular transitor is active and in this case prevents the corresponding source transistor (sink transistor) from conducting in sink operation (source operation). Therefore no crossover currents can occur. 1.6 Input Logic Truth Table Functional Truth Table IN1 IN2 OUT1 OUT2 Comments L L L L Brake; both low side transistors turned-ON L H L H Motor turns counterclockwise H L H L Motor turns clockwise H H H H Brake; both high side transistors turned-ON Notes for Output Stage Symbol Value L Low side transistor is turned-ON High side transistor is turned-OFF H High side transistor is turned-ON Low side transistor is turned-OFF Data Sheet 5 Rev.1.1, 2007-07-31 TLE 5206-2 Overview 1.7 Monitoring Functions Undervoltage lockout (UVLO): When VS reaches the switch on voltage VS ON the IC becomes active with a hysteresis. All output transistors are switched off if the supply voltage VS drops below the switch off value VS OFF. 1.8 Protective Function Various errors like short-circuit to + VS, ground or across the load are detected. All faults result in turn-OFF of the output stages after a delay of 50 µs and setting of the error flag EF to ground. Changing the inputs resets the error flag. a. Output Shorted to Ground Detection If a high side transistor is switched on and its output is shorted to ground, the output current is internally limited. After a delay of 50 µs all outputs will be switched-OFF and the error flag is set. b. Output Shorted to + VS Detection If a low side transistor is switched on and its output is shorted to the supply voltage, the output current is internally limited. After a delay of 50 µs all outputs will be switched-OFF and the error flag is set. c. Overload Detection An internal circuit detects if the current through the low side transistor exceeds the trippoint ISDL. In this case all outputs are turned off after 50 µs and the error flag is set. d. Overtemperature Protection At a junction temperature higher than 150 °C the thermal shutdown turns-OFF, all four output stages commonly and the error flag is set with a delay. Data Sheet 6 Rev.1.1, 2007-07-31 TLE 5206-2 Diagnosis 2 Diagnosis Various errors as listed in the table “Diagnosis” are detected. Short circuits and overload result in turning off the output stages after a delay tdSD and setting the error flag simultaneously [EF = L]. Changing the inputs to a state where the fault is not detectable resets the error flag (input toggling) with the exception of short circuit from OUT1 to OUT2 (load short circuit).
