Power management integrated circuits (PMIC) have been widely used in many applications due to their ability to integrate multiple power control functions in one device. Supervisors within PMIC play important roles in protecting the applications from fault conditions and resetting the system in case of a power supply fault. The MIC2774N-22BM5-TR is a high-performance supervisor device designed to meet the multiple power control needs of modern applications.

The MIC2774N-22BM5-TR is a power supervisor IC, designed to monitor and protect the power supply of an application. It features two main functions, namely power monitoring and power protection. Power monitoring is implemented with two power supply voltage monitors, one for the main power supply and one for the backup supply, which can detect voltage drops as low as 0.220V. It can also detect an overvoltage event on the main supply input. The two monitor pins can be used in conjunction with a dedicated reset output to warn the application if either of the monitored voltages drops below its configured threshold. The power protection feature is implemented through a programmable delay-based power-on reset circuit, which can provide a system reset if either the main supply or backup supply fails. The MIC2774N-22BM5-TR can also be used to detect and control a wide range of power supply fault conditions.

The MIC2774N-22BM5-TR is a tiny 6-pin SOT-23-6 package and is suitable for use in distributed power systems and battery-powered systems. It is especially suited for applications where the power supply voltage is close to the expected operating voltage of the microcontroller or other components. It is suitable for applications with supply voltages up to 26V. The device also has an active-low open-drain output, allowing it to be used with a wide range of microcontrollers and digital logic devices.

The MIC2774N-22BM5-TR includes a range of features that make it ideal for applications that require accurate voltage monitoring and safe system shut down in response to fault conditions. These features include a wide operating temperature range of -40C to +85C, an adjustable power-on reset threshold, a programmable delay-based power-on reset circuit, an overvoltage detect function, and a voltage monitor grade of 0.220V. All of these features provide better reliability and performance, allowing application designers to create reliable and efficient power solutions.

The MIC2774N-22BM5-TR is suitable for various applications, including single-board computers, portable computing equipment, battery-operated products, and embedded systems. It is also suitable for systems-on-a-chip (SoC) and system-in-a-package (SiP) applications, which require improved system-level protection and fault conditions detection.

In summary, the MIC2774N-22BM5-TR is a highly versatile and reliable PMIC supervisor device suitable for use in many different applications requiring accurate and reliable power supply monitoring and resetting. Its wide range of features make it an excellent choice for protecting embedded, battery-powered and distributed applications from unwanted power supply faults.
