For appropriately polarity recognition and corresponding switchover of a output stage of a proximity switch or the like connected to a supply voltage (VB), even while continuously activated, when a change in load polarity occurs, the proximity switch having in each case a high side driver and a low side driver, it is proposed to define on the output-side voltage axis between the positive supply voltage (+VB) and the negative pole or ground an upper and a lower detection window which sense the load configuration, each at a distance from the working points...
[ We claim:] [1.] A method for load polarity recognition and corresponding switching of an output stage even when continuously connected to a supply voltage (VB), said method comprising the following steps:detecting a change in load polarity using a load configuration detection stage (LCDS) which recognizes the polarity connection of the load, said load configuration detection stage having a first output signal which enables a high side driver and a second output signal which enables a low side driver, said high side driver maintaining said load at a fir...
