In case of overload the ground current and the power dissipation are increasing. The applica- tion has to take into account that all maximum ratings are observed (e.g. operating tempera- ture TJ and total ground current IGND, see Maximal Ratings). The maximum current limitation value (or overload detection threshold) of the parallel con- nected power stages is the summation of the corresponding maximum values of the power stages (IOUT(lim)x + IOUT(lim)y + ....).

TLE 6232 GP always works in slave mode whereas the microcontroller provides the master function. The maximum baud rate is 5MBaud. Applying a chip select signal at CS and setting bit 7 and bit 6 of the instruction byte to „1“ and „0“ TLE 6232 GP is selected by the SPI master. SI is the data input (Signal In), SO the data output (Signal Out). Via SCLK (Serial Clock Input) the SPI clock is given by the master. |
