Integrated clamp-diodes limit the output voltage when inductive loads are discharged. Four open-drain logic outputs indicate the status of the integrated ciruit. The following conditions are monitored and signalled: - overloading of output (also shorted load to supply) in active mode - open and shorted load to ground in active and inactive mode - overtemperature Circuit Description Input Circuits The control and enable inputs, both active high, consist of schmitt triggers with hysteresis. All inputs are provided with pull-down current sources. Not connected inputs are interpreted as low and the respective output stages are switched off. In standby mode (STBY = LOW ) the current consumption is greatly reduced. The circuit is active when STBY = HIGH. If the standby function is not used, it is allowed to connect the standby pin directly to VS. Status Signals : The status signals are undefined for 2ms after a power up event or a STBY low to high transition. Output Stages The four power outputs consist of DMOS-power transistors with open drains. The output stages are short circuit protected throughout the operating range. Each output has it's own zenerclamp. This causes a voltage limitation at the power transistor when inductive loads are switched off. Parallel to the DMOS transistors there are internal pull down current sources. They are provided to de­ tect an open load condition in the off state. They will be disconnected in the standby mode. Due to EMI measures there is an internal zenerclamp in parallel to the output stage. It gets active above 33V drain source voltage. This leads to an increasing leakage current up to 1 mA @ VDS = 40V. Protective Circuits The outputs are protected6) against current overload and overtemperature. If the output current i ­ n creases above the overload detection threshold I O for a longer time then tDSO or the temperature in­ Q creases above Tth, then the power transistor is immediately switched off. It remains off until the control signal at the input is switched off and on again. Fault Detection The status outputs indicate the switching state of the output stage. Under normal conditions is: ST = low � Output off; ST = high � Output on. If an error occurs, the logic level of the status output is inverted, as listed in the diagnostic table. 6) The integrated protection functions prevent an IC destruction under fault conditions and may not be used in normal operation or permanently. Page 7 2010-07-10 V4.1 Datasheet TLE 6228 GP If current overload or overtemperature occurs for a longer time than tDSO, the fault condition is latched into an internal register and the output is shutdown. The reset is done by switching off the corresponding control input for a time longer than tD-IN. Open load is detected for all four channels in on and off mode. In the on mode the load current is monitored. If it drops below the specified threshold value IQU then an open load condition is detected. In the off mode, the output voltage is monitored. An open load condition is detected when the output voltage of a given channel is below the threshold VDS(OL), which is typ. 33 % of the supply voltage VS. To prevent an open load diagnosis in case of transient Voltages on the outputs the open load detection in off mode uses a filter of typ. 50µs. Status output at pulse width operation If the input is operated with a pulsed signal, the status does not follow each single pulse of the input sig­ nal. An internal delay tD of typ. 1.2ms ( min 500 ms) enables a continuous status output signal. See the timing diagrams on the following pages for further information. This internal status delay simplifies diagnostic software for pwm applications. Diagnostic Table In general the status follows the input signal in normal operating conditions. If any error is detected the status is inverted.
