PMIC - Supervisors - MIC2777-17YM5-TR Application Field and Working PrinciplePower Management Integrated Circuits(PMICs) are critical components of modern electronics and are used across an incredibly wide range of applications. They provide the ability to efficiently manage and regulate the power supply of a variety of systems and are used in everything from low-power consumer electronics to industrial systems. A key type of PMIC is the Supervisors, which are typically used to monitor the state of standby voltage within a device or system. An example of a Supervisors PMIC is the MIC2777-17YM5-TR, which is manufactured by Microchip Technology. The MIC2777-17YM5-TR is a low-power voltage supervisor with a power-on-reset output, an adjustable delay time, and reverse supply protection capability. This particular device is designed for use in low-power applications, with a windowed reset threshold voltage of 1.7V and a wide operating voltage range from 1.1V to 5.5V. The MIC2777-17YM5-TR also provides additional functionality through its adjustable delay time, reverse supply protection capability, and power-on-reset output. These features make the device ideal for use in a variety of standby and power management applications, including mobile, consumer, and automotive applications. The MIC2777-17YM5-TR voltage supervisor provides a basic, yet reliable, application of power management. The device acts as a sensor that monitors the power supply voltage, and when the input supply voltage rises above or falls below the windowed reset threshold voltage, the device triggers a reset. This reset occurs after an adjustable delay time, which is set by the potentiometer on the device. The range of the delay time can be adjusted from 50µs to 500ms. Additionally, the device can be used in applications where the power supply may temporarily fall below the regulated level, as it is designed with reverse supply protection capability.The MIC2777-17YM5-TR power-on-reset output is active-low when the device is enabled and has detected a valid supply voltage. Once the power reaches the windowed reset threshold voltage, the output switches to a high state and remains there until the input supply voltage falls below the threshold voltage. The device also features an open-drain reset output and an active-high enable input. Additionally, the device is designed with Thermal Shut Down (TSD) protection, which deactivates the device when it reaches a certain temperature—typically 130℃. Overall, the MIC2777-17YM5-TR voltage supervisor provides an effective, energy-efficient solution for managing the power supply of various consumer, mobile, and automotive applications. With its adjustable delay time, reverse supply protection capability, power-on-reset output, and TSD protection, the device is a reliable choice for managing a variety of product designs. Moreover, the MIC2777-17YM5-TR comes in a small, surface-mount package, making it ideal for space-constrained applications.
