A reverse current protection circuit is coupled to a pass transistor of power circuitry (e.g., a power switch or voltage regulator), the pass transistor being coupled between first and second voltage nodes, the first voltage node being coupled to a power supply circuit. The reverse current ...
enhancement-mode, NMOS FETs to operate from battery voltages as low as 3.5V. Because the charge pump runs on the battery voltage and thus also needs protection from battery reversal, the circuit connects a diode between the battery's

If the battery is connected correctly, as shown, current flows through the diode to the circuit, and the circuit operates normally. If the battery is reversed, the battery tries to pull current through the diode the wrong way, and the diode refuses to conduct — protecting the load from dam...
Circuit with overload current protection for power transistors The purpose of the present invention is to protect the final transistor (PW) of a power actuator from short circuits and overloads with a completely integrated circuitry solution which would not influence the output impedance of the actu...
