MAX6806UR23+T

Power management integrated circuits (PMIC) are integrated circuits (ICs) that manage the power of a device. PMICs provide control over specific functions, such as voltage regulation and battery charging, and manage power delivery over multiple power tasks. Supervisors, also known as PMIC supervisors, are a type of PMIC that help prevent unnecessary power consumption, as well as system and design glitches in electronic systems. The MAX6806UR23+T is a advanced PMIC supervisor with a wide range of applications. This article will detail the MAX6806UR23+T’s application fields and working principles.

Application Fields
The MAX6806UR23+T is packed with features and multiple protections that makes it suitable for a wide range of applications. It is tailored-made for high-density mobile products, such as smartphones, tablets, Ultrabooks and notebooks, thanks to its single-package, low-power operation and tiny footprint. It is also well suited for applications that demand precise operation, higher current, and/or voltage regulation, such as servers, powering microprocessors and other precision-dependent components. This also makes it suitable for a wide range of consumer products and devices, such as battery operated portable devices, activity trackers, and other wearables.

Working Principle
The MAX6806UR23+T operates in two core mode – power enabled and power disabled. In power enabled mode, the device monitors the status of the circuit, including the battery voltage and system signals, to determine the requisites for power up and power down. The device also provides automatic power-on reset and power sequencing for the power rails of the system, such as power rails for microprocessors, audio codecs, and other precision components. In order to ensure low power consumption during operation, the device also includes adjustable programmable voltage supervisory, and powergood timer functions.

In power disabled mode, the device monitors the user-defined trip points and power rails, and provides system reset, power-on reset (POR), and power down reset (PDR) functions. In this mode, the device is designed to detect power glitches, overvoltage conditions, surge events, and any other voltage irregularities that might glitch the system. In these cases, the device will generate an open-drain active-low output, resetting the system and restarting the power-on sequence.

In applications that require precise operation, the device offers adjustable programmable voltage supervisory and powergood timer functions. The adjustable programmable voltage supervisor allows the user to set a voltage threshold at which the device will reset the system. This ensures that the system is reset before any erroneous operation caused by under voltages can occur. The powergood timer is also adjustable, and provides a programmable delay to ensure that the system is stable before the powergood signal is asserted.

The MAX6806UR23+T offers four levels of pre-assertions with different timings, enabling the user to define the sequence of operations. Additionally, the device features reverse polarity protection, short-circuit protection, open-drain active-low output, and voltage monitoring over several power rails. All these features make the device suitable for a wide range of applications.

The MAX6806UR23+T is a highly advanced PMIC supervisor which provides a highly efficient and reliable power solution for a range of devices. It offers robust protection, adjustable programmable voltage and powergood timer functions, and reverse polarity and short-circuit protection, making it ideal for a wide range of applications. This all in one power management solution also offers remarkable system stability, and many additional benefits for electronic systems.
