The absolute maximum drop is (V INmin – (V BATmax – V SD) = V Fmax), the USB 2.0 standard specifies 5V±0.25V, most lithium batteries charge to 4.2V and internal MOSFET diodes have a drop of around 0.6V, so (4.75 – (4.2 – 0.6) = 1.15). This maximum forward voltage drop is so the source (load side) voltage of Q1 doesn''t go …

Also, I have designed a number of products that connected a 3.3V LDO to the lithium battery. If you run until the LDO drops out (3.5 or 3.4) you actually do get most of the energy out of the cell. Especially if you are discharging at C/8 or C/10 (8 or 10 hour battery life). $endgroup$ –

Reverse battery current protection using LM74610 integrated circuit The LM74610-Q1 is a controller device that can be used with an N-Channel MOSFET in a reverse polarity protection circuitry. It is designed to drive an external MOSFET to emulate an ideal diode ...
You can not use a diode in series with a 5V supply to charge a lithium ion battery! This is very dangerous. You may cause a serious fire if you continue. You need a proper charger for the battery. The charger must limit the charging current to a safe level, and must limit the maximum charging voltage. Consult the data sheet for the battery to see what these …

A diode will do it but has problems. The voltage drop means your gate battery will never charge full, and your application likely requires higher currents which tends to rules out Schotky diodes which have unusually low voltage drop (350 to 500 mV as opposed to 0.7 to 1.5 V) are difficult to find in large sizes.
the Li-metal anode, the number of Li-metal anodes in the multi-layer laminated dual-anode battery system can be further reduced. Meanwhile, Li has the smallest density (0.534 g cm 3) among metals. Besides, as a highly commercialized semicon-ductor device
The simplest protection against reverse battery protection is a diode in series with the battery, as seen in Figure 1. + LOAD – VBAT – 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. When the battery is installed backwards, the diode ...

It includes a 1-cell Lithium ion battery protection chip and dual N-CH MOSFET with common drain. The chipset provides rich battery protection features and can turn-off the N-CH MOSFET by detecting overcharge voltage/current, over discharge voltage/current, or load short circuit.
$begingroup$ Because the intrinsic diode is in parallel with the FET. If you have two batteries connected the two FETs are turned on and there is a balancing current path available. The FETs short out the intrinsic diodes. So you have to put diodes in series with the battery to control battery to battery current. $endgroup$ –

Why not use a simple diode? Using a diode as reverse power polarity protection as shown in Circuit 1 is a very simple and reliable solution as long as you can afford the waste of power. The chances are that with a battery-operated device you do not want to waste power, particularly if your supply voltage is already quite low and so the …
