PMIC, or Power Management Integrated Circuits, is a family of integrated circuits that extract, regulate and protect an attached circuit or system from transients and other conditions that can cause damage or malfunction. Power Distribution Switches, Load Drivers, are an important part of PMICs. They provide a switch-selectable power supply or load, allowing the load management circuit to allow the power to be drawn from the appropriate source.The MIC2566-0YM-TR is a high-speed MOSFET load switch IC that can be used for low-voltage monitoring, active power-supply switchover, and power source selection. This device has a low RDS(on) of 0.7Ω and operates from a single +1.8V to +3.6V supply. It can switch from OFF to ON in less than 1μs. The integrated circuit can control up to four independent low RDS(on) MOSFETs and incorporate level shifters, so that its control signals may be driven by either an open axial or a logic-level supply.The MIC2566-0YM-TR is ideally suited for applications where the load is powered by multiple voltage sources and the power sources can be changed on demand. Typical applications include active power supply switchover, low voltage monitoring, and power source control in mobile and computer peripheral circuits.The device also features a reverse current protection circuit, which prevents device damage in the event that the channels are connected in the wrong direction. The reverse current protection circuit prevents current flow in the reverse direction. Additionally, the device has an analog input for both devices, which can be used to enable the load under software control.When the input logic signal is low, the load switch is OFF and all channels turn OFF. When the logic signal is high, all channels are turned ON, and all applications with load voltage greater than the supply voltage will be enabled.The MIC2566-0YM-TR is also designed to minimize power waste, minimize circuit complexity and minimize device size. To achieve this, the device uses a single voltage reference pin for all channels and does not require an external current-limit or over-current protection circuit.In terms of package footprint, the MIC2566-0YM-TR is the smallest IC with 4 channels and is typically used in high-density mobile applications, tablets, and notebook PCs. Its small package size also allows use in physically restricted areas.Overall, the MIC2566-0YM-TR is a very versatile device, which can serve as a low-voltage monitoring, active power-supply switchover, and power source selection for many different types of applications. The device is highly reliable and can be used in many different types of environments due to its wide operating temperature range. Its integrated features make it easily configurable to suit specific applications, therefore making it a great choice for designers who require high-performance, high-reliability, and easy-to-implement power management solutions.
