Integrated clamp-diodes limit the output voltage when inductive loads are turned off. For the detection of errors at the load there is a serial diagnostic interface, which monitors the following errors for every output separately: – open load in inactive mode – shorted output (shorted to ground) in inactive mode – overload or shorted load in active mode Circuit Description The block diagram shows the four independent power drivers with the referring logic block and the serial diagnostic interface which stores and transfers the diagnostic signals to the external circuit. Each power switch connects a high side load to ground when a LOW signal applies at the inputs. To protect the IC against short circuit and over load each output is provided with a current limitation and a delayed overload shutdown. The slew rate of the switching process is limited internally. The integrated clamp diodes limit the voltage at the output to VDS(AZ), when inductive loads are switched off. The maximum power dissipation, which is given from the static and dynamic thermal resistance, limits the allowable inductive energy. A diode in parallel to every output clamps negative voltage. All outputs, preferably the outputs 1 and 2 and the outputs 3 and 4 may be used in parallel (no addition of max. freewheeling energy). A curve of the output voltage is shown in figure 6. The diagnostic block monitors the voltages across the power switch. If in active mode (LOW level input) there is a higher voltage than VDS(OV) for a time longer than tVDS(OV), the diagnostic block will show an overload in the error register and the affected power switch will be shut off. The switch can only be reactivated if the corresponding input is switched off and then on again. In inactive mode (HIGH level at input) open load or shorted output (shorted load to ground) is detected and signalled to the serial diagnostic interface. If the voltage across the power switch is lower than VDS(OL) for the time tVDS(OL) (min. 50 µs) open load is identified. If the voltage is even lower than VDS(SH) for the time tVDS(SH) (min. 30 µs) "shorted to ground" is detected. An internal voltage divider will pull the output to the voltage VDS if there is an open load. A new error on the same output stage will over-write the old error report. The protocol of the serial diagnostic interface includes independent error reports for each output driver. As soon as an error is latched into the error register the serial data output (SEROUT) of the interface will go LOW (while CS is still HIGH). If the chip select gets a LOW signal Semiconductor Group 5 1998-06-22 TLE 5216 G (CS = L), all error reports can be shifted out serially. The rising edge of the CS will reset all error registers. The function of the serial diagnostic interface is shown in figure 7. The data input (SERIN) allows several TLE 5216 G or other serial diagnostic interfaces to be cascaded. A LOW signal on the reset pin (RESET) or a supply voltage lower than the operating range (4.5 V) will erase the error register and disable all four power switches.
