PMIC - Power Distribution Switches, Load Drivers are solid-state devices (SSDs) that connect or stop current flow to a supported load when directed to do so by a logic-level control signal that is insufficient or inappropriate for powering the load. To set them apart from comparable IC and discrete components, they include the semiconductor switching device needed to stop the current flow and incorporate additional supporting components/functions, including over-voltage clamping, current limiting, and under-voltage lockouts. A power switch establishes an electrical link from a power source to a load. It protects the power through various voltage barriers and protects the subsystems from getting damaged.
Difference between PMIC-Power Distribution Switches and Load Drivers:
PMIC-Distribution Switches
An electrical connection from a ground or voltage source to a load is made possible by a power switch. It conserves energy over numerous voltage rails and safeguards against harm to subsystems. Additionally, it lowers the size of printed circuit boards (PCBs), provides increased component safety, and prevents inrush current.
PMIC-Load Drivers
A PMIC- Load Driver IC is a circuit or component that regulates current flow to control another circuit or component. The driver IC serves as a bridge between a microprocessor or microcontroller and the output component, supplying accurate analog signals to turn on the display's pixels after receiving image data. Load Drivers are used to either connect or disconnect a load from a source to voltage down or up to save power when a load is not needed, and they are also used in sequential power on or off tasks.
