The interface is especially designed for the steadily reducing IO supply voltages in modern chipsets. It uses an open drain transistor with a bus pull-up circuit on the master side as physical interface. The pull-up can be passive or active.
MIPI Battery Interface can be used with smart or low-cost batteries, and removable and embedded batteries. It can also be applied in smartphones, tablets, laptops, IoT devices, and anything with a rechargeable battery, such as battery-powered tools.
