Supply turn-on voltage spikes
So my question is, for the situation of input connector power supply turn-on inductor spikes, what is the best practice protection circuit? In my particular case the voltages are 40->55V from a lithium battery pack with a mechanical on/off disconnector switch and some non-ideal cables/wires used to hook everything up.
Reverse Polarity Protection
One of the simplest things we can do to thwart those ingenious fools is to prevent the power to our circuit being connected the wrong way. I''d recommend you consider this for all your designs even if …
circuit analysis
With the battery connected in reverse the rectifier in the alternator would have been forward biased, causing a very high current to flow because it is connected directly to the battery. Luckily rectifier diodes can handle very high peak currents, so provided the fuse opened quickly they should have been protected.
Protection Mechanisms For Batteries & Their Charging Systems
In the worst case, the hiccup mode, with its repeated start-stop cycles, can cause permanent damage to some of the control electronic elements, such as op-amps and other control ICs. If the power is only being used for battery charging, then this might be alright. In other cases, where the power supply is shared by other sub-systems, it is best ...

Reverse Polarity Protection
Our circuit can''t tolerate a reverse connection of the batteries so we can be assured that sooner or later someone will do exactly that. How can we protect the circuit? The simplest approach is to add a …
How To Prevent an Inductive Load from Damaging Your Power Supply
Without this protection, your power supply can be damaged by high voltage spikes from these devices. Figure 1 shows an inductive load connected to a DC power supply. When the power supply is turned on, current flows through the coil and a magnetic field builds up around the inductor. That magnetic field is a source of potential …

Is a Schottky diode appropriate for reverse polarity protection?
Schottky''s do have higher reverse leakage current (due in part to their lower forward voltage). This spec will be in the datasheet and increases with temperature. Reverse leakage current is simply the deviation away from the ideal case in which there would be zero current flow. Having reverse leakage means it will eat some of your battery power.
