The MAX8923XETI+T is a high performance Power Management Integrated Circuit (PMIC) device. It integrates a device-level and system-level control, regulating and monitoring functions allowing design using a single chip to control the voltage and current requirements of any system with a single-chip solution.

The MAX8923XETI+T voltage reference is designed to provide a stable, precision-adjustable voltage for powering the system processors and memory. It works in the power supply range of 0.7V to 1.6V and can easily provide a precision level of 0.1V adjustment. It has a reference voltage accuracy of ±0.05% and is also accurate over load transients, transitional conditions, and temperature variations. The current range for the device can be set up to six times higher than the reference voltage and is used for system monitoring and control.

The MAX8923XETI+T voltage reference offers a few key features that help make it suitable for PMIC applications. First, it includes an adjustable voltage-drop voltage regulator to provide over-voltage and over-current protection on powered devices. This feature ensures safe and reliable operation in applications that require extreme power conditions. Second, the device includes a digital-programmable voltage-control algorithm to make certain the output voltage is within safe limits. Finally, the MAX8923XETI+T includes a safety timer to make sure the device will not overheat and cause the system to shut down.

The MAX8923XETI+T is designed to provide an adjustable reference voltage for use in power management. It supports many applications, such as powering microprocessors, memory, and other electronic components that require accurate voltage and current control.

The main application fields of the MAX8923XETI+T include consumer electronics, home appliances, communication products, industrial, medical equipment, and other applications that require adjustable reference voltage and output current control.

The working principle of the MAX8923XETI+T is to provide a stable, programmable, high-precision voltage reference. The device includes an adjustable voltage-drop voltage regulator to provide over-voltage and over-current protection on powered devices. It also includes a digital-programmable voltage-control algorithm to make certain the output voltage is within safe limits. The safety timer feature helps to prevent over-heating of the device.

The device is designed to be placed on the board or on an auxiliary board as an independent power management chip. It is controlled and monitored by the MCU and uses a serial I2C or SPI interface to communicate with the microcontroller. Once the voltage reference is programmed, it is capable of providing a regulated and stable output voltage to power the system.
