PMIC – Supervisors

PMIC (Power Management Integrated Circuit) is one of the most versatile types of integrated circuits used in a wide range of applications, ranging from consumer electronics to automotive, industrial and medical applications. PMIC supervisors are processors that monitor and control system power. Such supervisors can help ensure that components such as power supply components and system-level supportive block act in a way that meets the system’s power requirements.

ADM697AN is a family of versatile, robust power supply supervisors developed by Analog Devices. These devices feature a wide operating voltage range of 1.2V to 5.5V and are designed for use in various power management solutions. ADM697AN has three dedicated input pins for monitoring the power supply rail, and it performs functions such as monitoring and controlling the operating voltage of power rails, as well as acting as a system reset controller.

ADM697AN applications include cell phone chargers, laptop battery charging, linear and switch-mode regulators, and many other power management solutions. It is also suitable for automotive systems, consumer electronic devices like tablets and media players, and industrial equipment. The ADM697AN supervisors are used across a wide range of industries, and they are known for their features such as wide operating voltage range, robust protection capabilities, and a wide range of functionality.

ADM697AN Application Field and Working Principle

ADM697AN is a versatile power supply supervisor that provides a wide range of functions. It can detect power supply overvoltage, undervoltage, and overcurrent conditions. It also supports a wide range of reset and monitoring functions. In addition, it can provide power-up/down sequencing for various power rails.

The ADM697AN has three dedicated input pins for monitoring the power supply rail. These pins are VIN+, VIN-, and VBST. The VIN+ pin accepts an analog supply voltage from the power supply rail, and the VIN− pin provides a reference voltage. The VBST pin is used to monitor the power output of a boost converter.

The ADM697AN has a number of features that improve system reliability. It comes with an internal voltage supervisor, a power-on reset (POR) generator, and an overvoltage lockout (OVLO). The internal voltage supervisor monitors the system\'s voltage level and reset the device if the voltage becomes too low. The power-on reset generator prevents the system from resetting in the absence of any system input. The OVLO feature detects if the system voltage is too high and shuts down the system to prevent damage. The combination of these features makes the ADM697AN an ideal choice for a wide range of applications where system reliability and protection are essential.

The ADM697AN’s wide operating voltage range of 1.2V to 5.5V, robust protection capabilities, and a wide range of functionality make it an ideal choice for multiple power management solutions, from cell phone chargers, laptop battery charging, to automotive systems and industrial equipment. The device’s wide compatibility with different voltage rails and power management applications make it a versatile solution for various power management needs.
