Diagnostic Functions Page 4 10 05.December 2000 Data Sheet TLE 6225 G Functional Description The TLE 6225 G is a quad channel low-side switch with four power DMOS stages. 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 - Program pin. PRG = High: Parallel inputs Channel 1 to 4 are high active PRG = Low (GND): Parallel inputs Channel 1 to 4 are low active. 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 functions. 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 Page 5 05.December 2000 Data Sheet TLE 6225 G Diagnostic Table Enable Input Program Input Control Input Power Output Diagnostic Output ENA PRG IN OUT FAULT Standby L X X OFF H Normal function H H H H L L H H L H L H ON OFF OFF ON L L H H Overtemperature H H L H L H OFF * OFF * H L Open load or short to ground H H H H L L H H L H L H ON OFF OFF ON L H L H Operating Condition 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.
