On the other hand, you can configure connectors for rechargeable battery packs so that momentary reverse connections are impossible unless the user modifies the connector. The
In my product the user will be using a single ''unprotected'' Li Ion cell and when inserting the cell could reverse the battery. My question is: Will the BQ2973 survive a
A battery cell is the most basic functional unit of a lithium-ion battery. Looking at its structure, each battery cell contains five key components: a positive electrode (cathode), a
battery types, like single-cell alkaline, are not so easily protected by mechanical safeguards. Therefore, battery powered equipment designers and manufacturers must ensure that any
Although "Cell reversal" is less common in lithium-ion batteries compared to nickel-based batteries, it is still essential to understand its causes, consequences, and prevention

The result can be a short circuit, or discharge to undervoltage with a protection event in battery. Therefore, most cell manufacturers specify that the battery pack must be protected from reverse charging connection. Figure 1-2 shows an example of specification from usual cell manufacturer as part.
In general, these batteries offer no mechanical means for preventing the reversal of one or more cells. For these systems, a designer must ensure that any flow of reverse current is low enough to avoid damaging the circuit or the battery. A variety of circuits can provide this assurance.
The simplest protection against reverse battery protection is a diode in series with the battery, as seen in Figure 1. Figure 1. Diode in Series With Battery In Figure 1, the diode becomes forward biased and the load's normal operating current flows through the diode.
A reverse connected battery will lift the source of MP1 above its gate, which is connected to the charger's positive terminal. The drain of MP1 then, in turn, delivers current to the base of Q1 through R1. Q1 then shunts the gate of MN1 to ground, preventing the charge current from flowing in MN1.
The reverse connection pulls the charger side voltage down until the detection and protection circuits disengage it, allowing the charger to return safely to its constant-voltage level. Dynamics will vary by application and capacitance on the battery charger will play a large role in the outcome.
The DW01A chip is a battery protection device for a single cell Lithium Ion battery protecting the cell from over and under charging (by controlling maximum and minimum voltage to the cell), reverse connection, short circuit and it can prevent deep discharge of the battery.
