Introduction to X5045P-4.5A Supervisors
The X5045P-4.5A is a highly efficient and reliable power-management integrated circuit (PMIC) Supervisor designed and manufactured by NXP Semiconductors (formerly Freescale Semiconductor). It is a multi-output, programmable voltage supervisor IC that efficiently manages a variety of power supplies and system power-on reset. This highly programmable supervisor is specifically designed to fit into consumer and automotive applications in demanding automotive and other harsh environmental conditions.
Application Field
The X5045P-4.5A is a flexible integrated circuit that can provide up to four regulated DC output voltages from a single system power rail. This PMIC Supervisor is commonly used in consumer applications, such as portable appliances, consumer audio-video products, PCs, tablets, and other systems. Additionally, it is also suitable for automotive applications such as in-vehicle communication and navigation systems. The low-voltage start up, programmable reset timing, and over voltage and over current detection are only a few of the many features that makes the X5045P-4.5A a leading-industry product.
Working Principle
The X5045P-4.5A Supervisor has a unique hierarchical design, which begins with an internal comparator that monitors both system power and supervisory voltage rails. Once the comparator detects a power-on reset, the IC then triggers the other internal functions including the reset monitor, system voltage detectors, and the output switches. The supervisor has an internal oscillator which provides an adjustable fixed delay for the reset signal and monitors power supply signals for over-voltage, under-voltage, and over-current conditions. Additionally, the supervisor also monitors current to external output devices as well as provide protection against excessive inrush currents.
Once the internal comparator detects a power-on reset condition, a reset signal is sent to the system controller. The reset signal is delayed by the internal timer, providing plenty of time to power-up the system. The internal voltage detectors detect the system voltage and either allow or prevent the reset signal from proceeding to the system controller. The external current pumps continuously monitor the output devices and shut off power to them if an over-current condition is detected. With multiple output voltage options and precise voltage control, the X5045P-4.5A Supervisor is ideal for powering complex system designs.
The X5045P-4.5A Supervisor features an integrated bootstrap circuit that prevents deadlock when power supplies are unstable at start-up. The integrated circuit also features an optional sleep mode for applications with low power consumption requirements. In addition, its distributed design includes an active high reset output, four regulated voltage outputs, and dual main system voltage monitor inputs. It also features a low voltage brown-out detection and system reset timing range from 5 to 150 ms. The supervisor also has an integrated over-voltage protection that prevents surges and other voltage spikes during system powering up.
The X5045P-4.5A supervisor is a highly functional device that can make any system more efficient and reliable. Its small footprint and integrated protection features make it a great choice for automotive and other harsh applications. This IC is also pin-tailored for improved PCB design and enhanced thermal performance. Its ease of use, integrated features, and flexible design make it one of the best power-managers in the industry.
Conclusion
The X5045P-4.5A Supervisor is a power-managing integrated circuit designed and manufactured by NXP Semiconductors. It has many features such as its voltage detectors, over-voltage and over-current protection, low voltage start-up, and system reset settings that make it an ideal device for applications in consumer, automotive, and other harsh environments. This highly reliable supervisor is feature-rich and well-adapted for a variety of systems, making it an excellent choice for a variety of projects.
