Alpha & Omega Semiconductors app note about MOSFETs used in battery protection circuits. Link here (PDF)
Power MOSFETs are required to be connected in series between the lithium-ion battery pack and the output load. At the same time, a dedicated IC is used to control the on and off of the MOSFET for managing the charge and discharge of the battery. In consumer electronic systems such as cell phones, laptops, etc., the complete circuit system with control IC, power MOSFET, and other electronic components is called the Protection Circuit Module (PCM).
The PCM requires a low on-resistance MOSFET, so N-channel power MOSFETs are usually used. Some applications use P-channel MOSFETs on the positive end due to simple and flexible driving. However, P-channel MOSFETs on-resistance is relatively higher than N-channel MOSFETs and the selection is also limited.
