If logic chips are only programmed after the circuit board has been completed, it is often advisable to apply the required voltages directly to the outputs of the system power supply. However, this untypical wiring can lead to damage to components. This article shows how much damage can be prevented.
Subsequent programming of logic chips is particularly common in test and measurement systems or in building automation. So that FPGAs, DSPs or microcontrollers can be programmed, the corresponding supply voltages must be available in the circuit To be available. In the simplest case, the normal input voltage that is also present in regular system operation is used. For various reasons, however, this may turn out to be impractical.
