PMIC - Supervisors

The X5323PZ-4.5A is a three-in-one supervisor PMIC designed to provide over-voltage and brown-out protection, as well as power sequencing and control. It is suitable for applications ranging from consumer and communications systems to industrial and automotive. In this article, we will explore the application field and working principle of the X5323PZ-4.5A.

Application Field

The X5323PZ-4.5A is suitable for a wide variety of applications, ranging from consumer and communications systems to automotive and industrial applications. In consumer and communications systems, it is suitable for embedded and peripheral systems, including mobile phones, digital set top boxes, and home networking systems. It is also suitable for automotive autonomous sensing and control systems, industrial automation systems, and other IoT (Internet of Things) and industrial applications.

Working Principle

The X5323PZ-4.5A is a PMIC, or power management integrated circuit, designed to monitor and control the input, output, and enable voltages of a system. It is designed to provide over-voltage and brown-out protection, as well as power sequencing and control. It consists of three integrated linear regulators, and a power management unit. The three linear regulators provide adjustable over-voltage protection, adjustable under-voltage protection, adjustable load line regulation, and adjustable output voltage regulation. The power management unit provides power sequencing and control, as well as low quiescent current operation and thermal management.

The X5323PZ-4.5A’s power management unit is based on a proprietary TPS2547 high-current switch. Its power supply control logic consists of several voltage monitoring circuits, a discrete electronic switch, and a comparator. This combination of circuitry enables the X5323PZ-4.5A to monitor the power supply voltages and react to fault conditions, such as an over-voltage or under-voltage condition. When an over-voltage or brown-out condition is detected, the power supply control logic will instantaneously shut down the system power.

In addition to its over-voltage and brown-out protection, the X5323PZ-4.5A provides several other features. It is designed to provide fast power sequencing, with output settling times as low as 50us. It can also provide an adjustable margin of safety, up to 5% over the nominal voltage of the system.

The X5323PZ-4.5A is a versatile PMIC, suitable for a wide range of applications. It provides over-voltage and brown-out protection, as well as power sequencing and control. Its combination of features makes it ideal for embedded and peripheral systems, as well as automotive and industrial applications.
