High-side Protection Circuit Required for Short-circuit Protection in Metal-cased Batteries
This circuit enables Nch high-side protection, which is necessary for short-circuit protection in metal-cased batteries.
By placing the Nch MOSFETs, which control charging and discharging, on the positive side (high-side) of the lithium battery, the ground levels of the battery pack and system can reach the same voltage.
