I. Core Advantages and Design Philosophy of the Solution

The NXP 5V PMIC solution is built around five core design principles: “high integration, configurability, strong compatibility, high security and low power consumption”. It addresses the pain points of traditional discrete power supply components—such as cumbersome layout, complex debugging and poor compatibility—to achieve integrated control of the power supply system, comprehensively meeting the stringent requirements of various 5V power supply systems.

- High integration, streamlined hardware layout: A single chip integrates multiple DC/DC switching regulators, LDO linear regulators, power sequencing controllers, voltage monitoring, watchdog timers, battery charging modules and more, significantly reducing the number of external discrete components, minimising PCB footprint, and lowering hardware costs and R&D debugging complexity.

- Flexible programmability, suitable for multiple platforms: Supports OTP (One-Time Programmable) and I²C bus online configuration, allowing flexible setting of output voltage, current limits, switching frequency and power sequencing. It is fully compatible with NXP’s i.MX series MPUs, Kinetis series MCUs and various embedded processors, enabling a single solution to support multiple platforms.

- Wide voltage range and strong operational adaptability: The core PMIC chip supports a wide 5V system input range of 2.5V–5.5V, accommodating multiple power supply modes including battery, adapter and bus power. It maintains stable output even in the face of voltage fluctuations and transient interference.

- Functional safety compliance, meeting automotive and industrial requirements: Multiple products have obtained AEC-Q100 automotive certification and support ASIL B/D and SIL 2 functional safety levels. They incorporate comprehensive protection mechanisms against overvoltage, overcurrent, overtemperature and short circuits, making them suitable for high-reliability applications such as automotive electronics and industrial control.

- Ultra-low power consumption design for extended battery life: Optimised for low-power applications such as portable devices and the Internet of Things (IoT), these solutions minimise quiescent current and sleep mode power consumption. They support light-load high-efficiency modes and deep sleep wake-up mechanisms, balancing high-efficiency operation at full load with low power consumption in standby mode, thereby significantly extending the operational duration of battery-powered devices.

- Comprehensive ecosystem to accelerate product deployment: Supplied with complete evaluation boards, reference designs, GUI debugging software and technical documentation, supporting rapid prototype verification and parameter tuning, significantly shortening the R&D cycle and lowering the barrier to solution development.

II. Core 5V PMIC Product Portfolio

NXP has launched a range of differentiated 5V PMIC products tailored to various application scenarios and performance requirements, covering four major categories: entry-level, high-performance, automotive-grade and low-power. These allow for flexible selection based on specific needs:

III. Typical System Architecture for 5V PMIC Solutions

NXP’s 5V PMIC solutions adopt a ‘single-chip centralised management’ architecture, enabling complete 5V power conversion, distribution, management and protection without the need for complex discrete power circuits. The typical architecture is as follows:

1. Power Input Path

Supports multiple input methods, including 5V adapters, USB 5V power supply, in-vehicle 5V bus, and lithium-ion battery packs (post-regulation). The PMIC incorporates an integrated input voltage monitoring module that continuously monitors input conditions to address anomalies such as voltage sags and surges.

2. Power Conversion and Output

Through an integrated high-efficiency DC/DC switching regulator, the 5V input is converted into multiple low-voltage outputs required by the processor core, peripherals, sensors and communication modules; coupled with an LDO linear regulator, it provides low-noise, high-precision power supply for analogue circuits and RF modules, ensuring signal integrity.

3. Timing and Control Chains

A built-in programmable power sequencing controller strictly adheres to the processor’s power-up and power-down sequences when outputting voltages to each channel, preventing chip damage caused by timing anomalies. It supports communication with the host controller via the I²C bus to enable dynamic voltage adjustment, operating mode switching and status reading.

4. Protection and Safety Features

Integrated over-voltage protection (OVP), over-current protection (OCP), over-temperature protection (OTP) and short-circuit protection (SCP). Automotive and industrial variants additionally support watchdog, system fault diagnosis and power failure alarms, ensuring comprehensive power supply safety.

5. Battery Management Extensions (Optional)

For portable devices, built-in battery charging and power path switching functions can be enabled, allowing automatic switching between 5V adapter power and battery power. It also supports RTC power supply via a coin cell battery to meet the device’s power-off memory requirements.
