The MIC5801YN is a power distribution switch, load driver, and power management integrated circuit (PMIC) designed specifically to control power distribution in a wide variety of applications. The switch and load driver provide power control between two power supplies, while the power management features monitor the voltage, levels and current flow within the two power supplies. This set of services makes the MIC5801YN a versatile and powerful PMIC.The MIC5801YN consists of two main blocks, a stand-alone, non-configurable switch and a configurable load driver. The switch, often referred to as a logic-controlled MOSFET, is the core component of the MIC5801YN and is used to control the power distribution within the system. The switch is configured so that when the logic state is active, power distribution to the load device is enabled, and when the logic state is inactive, power distribution to the load device is disabled. This structure is typically used in applications where power is not constantly required, such as mobile phones and digital cameras.The load driver consists of two separate channels and is used to increase the amount of power available to the load device. Each channel is P- and N-type, and each is configured to drive one phase of a bridge rectifier. The load driver is designed to create higher power levels than the switch alone and allows for finer control of the load device. Additionally, the load driver can be used to handle higher levels of inrush current than the switch alone.The power management IC of the MIC5801YN allows for further monitoring and control of the two power supplies by way of two LED indicators. These LED indicators display the voltage and current levels of the two power supplies, allowing the user to monitor the voltage and current levels of the system without having to constantly check the power supply. Additionally, the MIC5801YN also includes programmable over-current and over-voltage protection to prevent damage to the system from excessive current or voltage.In conclusion, the MIC5801YN is a powerful and versatile power distribution switch and load driver, along with integrated power management ICs for monitoring and controlling current and voltage levels within the two power supplies. It is ideal for systems where power is intermittently required and offers a wide range of features that make it a great choice for a variety of electronic devices.
