A universal problem in battery-operated devices is the threat of damage when an end user (never an engineer) inserts the battery backward. You can avoid damage by inserting a single diode or by using ...

To prevent extensive damage during operational life, these systems require the design-in of systems that – at a certain voltage level – provide protection from voltage polarity reversal. This article ...

Accidentally connecting a battery reverse can be a real killer in electronic circuits. There are a number of ways to provide protection and all have the expected advantages and disadvantages. Any ...

In this circuit, a MOSFET protects a reverse-connected battery from excessive current. The MOSFET conducts only when the battery is correctly connected, which lets the battery charge or discharge. In ...

A123 Systems has been granted a patent for a battery management system (BMS) with a protection circuit to prevent unexpected switching ON. The system includes a cutoff circuit, reverse bias protection ...

It's vital that MOSFET power-switch drivers be protected from a reverse-battery connection. A small rectifier diode can shield against reversed batteries. But that approach is generally unacceptable ...

Abstract: An intelligent power MOSFET with built-in reverse battery protection, which is important for automotive power switches, has been developed. The protection is accomplished by integrating an ...

As they took him away, Clyde realized that leaving out that protection FET to save $0.35 had been a poor design decision. (Courtesy of Autoevolution) Electronics and automobiles have a long history ...

The PMP9498 reference design from Texas Instruments is a complete front-end protection solution for automotive systems requiring reverse voltage, over-voltage and over-current protection. Load switch ...

UPS Hat is a 5v power supply, It fit at the top of the raspberry pi, it gives power backup, while raspberry pi's USB power is cut off. It has various protections like short circuit protection, reverse ...

Abstract: When MOSFET is used as a power switch, it is essential to prevent reverse current flow through the parasitic body diodes under reverse voltage condition. A new built-in reverse voltage ...
