Abstract

A battery protection circuit has two input nodes and two output nodes. The input nodes are connected to a positive supply line and a negative or ground line respectively, and the two output nodes are connected to a positive side of a load and a negative or ground return side of the load. The circuit includes a solid state switch which is oriented such that when the switch is open current cannot flow from the battery through the load. At least one capacitor is connected in series with a diode between the two input nodes of the circuit to smooth out any negative transient voltages present at the positive input node of the circuit. The capacitor includes a polarized capacitor and the diode is oriented to protect the capacitor during normal use when a positive voltage is present at the input node that is connected to the positive supply line.
