Power Management Integrated Circuits (PMICs) are a type of integrated circuit used to manage the power of a system. They are used in both consumer and telecommunications products to regulate current, proper power delivery and distribution, protect against short circuits, and manage power supply. They are primarily used in communications and computing devices, including cellular phones, smartphones, tablets, netbooks, notebooks, and desktops.

One type of PMIC is the Power Distribution Switch, Load Driver, or TPS2220BPWP. This integrated circuit is specifically designed to provide efficient and reliable power distribution control and load driving functions for electronic equipment with limited available power resources. It features an over-voltage protection circuit and programmable load switch with wide input voltage range, low standby power consumption, low on resistance, and low quiescent current.

The TPS2220BPWP has two major operating modes: Power-on and Power-off. In Power-on mode, the integrated circuit sources current from either Portable Battery or AC adapter to various electronic circuits. When the Power-on mode is activated, the TPS2220BPWP turns on and the load switch is opened allowing the current to flow normally. In Power-off mode, the current path is blocked to avoid over-current damaging the system.

TPS2220BPWP is designed for a variety of applications such as automotive infotainment systems, portable media players, digital still/video cameras, portable DVD players, and battery-powered equipment. It is suitable for high-side loads and current levels up to 3 amps. It also provides a precise current overflow protection circuit, advanced current sense-and-PWM control, and a wide-range of safety features.

When designing a product to run on battery or AC power, the TPS2220BPWP is an ideal solution for providing reliable current distribution. It offers low quiescent current and low power dissipation to conventional buck or boost converters. It features adjustable-on-resistance, optimized for total current protection at the same time
