and electrolytic capacitors have a famous tendency to explode. For this reason, it’s common to use a blocking diode in a circuit to provide reverse polarity protection:
A voltage protection circuit that has a protection transistor coupled between a voltage supply pin of an integrated circuit and a voltage output terminal of the integrated circuit. A biasing circuit is coupled to a control node of the protection transistor and configured to cause the protection ...
The present invention relates to a reverse voltage protection circuit of a power conversion apparatus and a reverse voltage protection method using the same. In addition, the present invention includes: a first transistor which is turned on by voltage applied from an auxiliary battery and turned off...
It is possible to develop a reverse voltage protection circuit for battery charger based applications. Some circuits were developed and abbreviated testing was performed with encouraging results. There is no silver bullet to the reverse battery problem but hopefully the approaches shown provide sufficient...
A number of circuit configurations for protection of CMOS circuits against erroneous connections to the surrounding world (e.g. reversal of the supply voltage) are suggested and analyzed. It is found that protection against any permutation of input connections, output connections, and supply voltage ...
(VBATT+10V). This circuit allows standard, 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 positive terminal...

A reverse-voltage protection circuit for MOSFET power switches When MOSFET is used as a power switch, if is essential to prevent reverse current flow through the parasitic body diodes under reverse voltage condition. A... HP Hong,JC Wu - 《IEEE Journal of Solid State Circuits》 被引量: 31...
The protection circuit works by interrupting the flow of power to the device’s electronic components, shielding them from electrical damage. Reverse polarity protection is particularly vital in industrial environments where DC power supply systems often deliver significant power. Without this safeguard, ...
