PMIC - Power Distribution Switches, Load Drivers

The MAX8586ETA/V+T is a highly integrated system-on-chip (SoC) solution for managing power distribution and load control in a mobile device. This device includes three integrated power switches, two smart loads and two loading drivers, as well as several background and control functions such as output linear regulator, low-dropout (LDO) regulator, power management, system monitor and thermistor. It provides a complete solution for power management and charge control in a compact package.

Application Fields

The MAX8586ETA/V+T is ideally suited for use in mobile phones and portable short-range communication products. The integrated power switches and smart loads are designed to provide efficient power management, providing up to 3W output, reducing the time and hassle of design and implementation of power management in a single package. The low-dropout (LDO) linear regulator and power management subsystem provide a complete power solution with multiple power rails and system protection. The integrated system monitor and thermistor functions provide complete and adjustable protection for the device.

Working Principle

The MAX8586ETA/V+T consists of three power switches and two smart loads, connected in series. The power switches provide up to 3W output, controlled by the external control pin. The smart loads provide the current sensing and over-current protection function. The external control pin controls the output voltage, monitoring the output voltage and current to maintain the output voltage in regulation. The low-dropout (LDO) linear regulator is used to provide the output voltage to the devices. The integrated power management subsystem reduces the current consumption when the output voltage is reduced, or when the device is in idle mode, providing additional system efficiency and power savings. The integrated system monitor and thermistor functions provide additional system security, monitoring the external conditions and reacting accordingly.

The MAX8586ETA/V+T provides a complete solution for system management in mobile and portable products. This device includes multiple power, system monitor and thermistor functions, providing reliable, cost-effective and efficient power management solution within a compact package. The integrated smart load delivers accurate current sensing and over-current protection while the low-dropout (LDO) linear regulator and power management subsystem provide complete and adjustable protection for the device.
