PMIC - Power Distribution Switches, Load DriversThe L9781 is a power management integrated circuit (PMIC) commonly used for power distribution switches and load drivers. Its internal features include a wide range of options for voltage regulation, power sequencing, and protection. It is a replacement for other PMICs and controllers in a wide variety of applications. The L9781 is also ideal for powering a variety of embedded applications.The operating principle of the L9781 is based on low noise control. This control method accounts for the power efficiency, as power is only delivered when required. The L9781 exclusive low noise control reduces system noise and power fluctuations by maintaining a constant voltage. By stabilizing the power fluctuations, the L9781 helps deliver a consistent and reliable power supply.The L9781 is designed to deliver a regulated output within the range of 0.9V-6V. Once the input voltage is applied, the “power on” output voltage is linearly ramped up to its setpoint without the need for external components. An integrated soft start circuitry helps limit the inrush current of the output to protect downstream components on power up. A power-down option is also available, allowing the system to be smoothly shut down.The L9781 also offers overvoltage protection. The device contains circuitry to monitor and detect overvoltage events, providing system protection and improved reliability. The device also has an overload protection feature which prevents system damage in the event of an overload situation.In addition, the L9781 has advanced power sequencing capability, allowing the user to sequence up to 8 power supplies. This power sequencing ensures that the power supplies are turned on or off in the correct sequence, increasing system reliability.The L9781 is available in a standard package that is RoHS compliant, and also offers a wide range of pinouts and footprints. This makes the L9781 a versatile and easy to use solution for applications requiring a replacement for other PMICs and controllers.The L9781 is well suited for a variety of industrial and consumer applications including appliances, automotive, gaming and processor cores. Its wide range of features and low noise control makes the L9781 a great choice for powering a variety of embedded applications. Its small size and low cost also make it the ideal choice for cost-sensitive applications.
