Batteries offer their optimal performance in the form of efficiency and output when they operate within these parameters. By managing factors such as charge/discharge rates and operating temperature, protection mechanisms ensure optimal function.
Providing battery-reversal protection for battery voltages lower than 2.7V, on the other hand, can be a challenge. One solution is to use a bipolar transistor, which entails base-current losses. Another is the use of a low-threshold PMOS FET with a charge pump for driving the gate voltage below ground (Figure 6). This circuit can operate with 5V or 3.3V output voltages. Although

Abstract. Many self-contained critical electronic systems and subsystems, especially in automotive applications, use a 12 V or 48 V storage battery for the primary power source. 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.
replaces traditional solutions based on power diodes and P-channel MOSFETs. Apart from providing protection against input polarity reversal, an input protection solution should also safeguard downstream electronic circuits from various system-level transient events. Automotive standards such as ISO 7637-2, VW 80000 (LV124) and ISO 16750-2 define such system-level

As batteries can store a huge amount of energy, so sudden discharge or fault can result in catastrophic failures. By handling and maintaining the battery’s functional factors, and protective mechanisms, avert these unsafe operations and prevent dangers such as overcharging, overheating, and short circuits.
Similarly, during a high-load function, over-current protection strives to keep the current within the protected limit, however, during the same high-load function, under-voltage protection makes sure that the battery does not get discharged.
