The power transistors are protected against short to VBB, overload, overtemperature and against overvoltage by zenerclamp. The diagnostic logic recognises a fault condition which is indicated by a fault flag. Circuit Description Output Stage Control Each output is independently controlled by an input pin and a common enable line, which enables/disables all four outputs. The parallel inputs are high or low active depending on the PRG pin. If the parallel input pins are not connected (independent of high or low activity) it is guaranteed that the outputs 1 to 4 are switched OFF. ENA - and PRG - pin itself are internally pulled down when they are not connected. ENA - Enable pin. ENA = High: Active mode. Channels are enabled ENA = Low (GND): Sleep mode. Channels are switched off. Less than 1 µA current consumption. PRG = High: Parallel inputs Channel 1 to 4 are high active PRG = Low (GND): Parallel inputs Channel 1 to 4 are low active. PRG - Program pin. Power Transistors Each of the four output stages has its own zenerclamp. This causes a voltage limitation at the power transistors when inductive loads are switched off. The outputs are provided with a current limitation set to a minimum of 500 mA. Each output is protected by embedded protection functions3). In the event of an overload or short to supply, the current is internally limited. If this operation leads to an overtemperature condition, a second protection level (about 170 °C) will turn the effected output into a PWMmode (selective thermal shutdown with restart) to prevent critical chip temperatures. The temperature hysteresis is typically 10K. Diagnostic The FAULT pin is an open drain output. The logic status depends on the programming pin PRG. FAULT - pin. FAULT = High FAULT = Low no fault @ PRG = High no fault @ PRG = Low 3) The integrated protection functions prevent an IC destruction under fault conditions and may not be used in normal operation or permanently V2.1 Page 5 26.Aug. 2002 Data Sheet TLE 6225 G Diagnostic Table Enable Input Program Input Control Input Power Output Diagnostic Output Operating Condition Standby Normal function ENA L H H H H H H H H H H PRG X L L H H L H L L H H IN X L H L H L H L H L H OUT OFF ON OFF OFF ON OFF * OFF * ON OFF OFF ON FAULT H L L H H H L L H L H Overtemperature Open load or short to ground X = not relevant *selective thermal shutdown for each channel at overtemperature Fault Distinction Open load/short to ground is recognised in OFF-state. Overtemperature as a result of an overload or short to battery can only arise in ON-state. If there is only one fault at a time, it is possible to distinguish which channel is affected with which fault.
