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 ...

The algorithm for this circuit is that the blocking MOSFET must be disabled if the battery voltage exceeds the battery charger output voltage. In this circuit MN1 is connected in the low side of the ...

Different reverse-polarity solutions and their effectiveness at providing car battery front-end protection. How a smart diode controller can provide optimal reverse-battery protection. If the battery ...

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 ...

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 ...

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 ...

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 ...

80V Low IQ Ideal Diode Controllers from Diodes Incorporated Simplify Reverse Battery Polarity and Overvoltage Protection in Modern Automotive Architectures Diodes Incorporated (Nasdaq: DIOD) today ...

According to the company, when combined with Breaktor circuit protection technology, which combines current switching and reconfigurable bi-directional short circuit protection with fast tripping, ...

Lithium batteries have, nearly single-handedly, ushered in the era of the electric car, as well as battery energy storage of grid power and plenty of other technological advances not possible with ...
