发明名称 Circuit to protect vehicle components from inadvertent reversal of battery polarity or from negative voltage spikes
摘要 The protection circuit has an input connected to the battery terminal and an output for the load to be protected. An inversely-driven N-channel MOSFET (t1) has its source connected to the input and the drain with the output. The gate is joined to an external voltage source providing a higher voltage than the voltage available for the load. Between the source and the drain is a voltage-controlled bipolar NPN transistor (t2) with a resistance (r2). Between its base and emitter is a diode (d1) and between the base and earth is a second resistance (r3).
