Power management integrated circuits (PMICs) alongside supervisors, which include overvoltage (OVP) and undervoltage (UVP) protection devices, are a class of product used to monitor and manage power throughout an electronic system. Used in both industrial and consumer applications, PMICs are a critical safety feature of any system requiring high voltage, current, or temperature management. The Texas Instruments LP3470M5-2.63/NOPB device is a five-channel PMIC supervisor that provides a number of key features, including adjustable trips on each of its five channels, short circuit protection, and a wide input voltage range.

Introduction

The LP3470M5-2.63/NOPB is a supervisor IC designed to monitor and regulate power in both industrial and consumer applications. It offers superior performance, adjustable trips and adjustable delay timing for each of its five channels, comprehensive diagnostics for improved system reliability, very low power consumption, and a wide input voltage range making it suitable for a broad range of applications. The device can monitor voltage or temperature, with outputs that can be used to either directly trigger a power control module or generate an interrupt or reset signal.

Application Field

The LP3470M5-2.63/NOPB is recommended for a wide range of digital applications, including industrial PC (IPC), enterprise server, and handheld device designs. It can be used in applications such as secure computing, embedded computing, communications equipment, medical diagnostics, avionics, industrial motor control, factory automation, energy storage, and automotive products. The device is also well suited for applications requiring OVP and UVP protection, such as battery management systems, charge controllers, power supplies, and solar panel controllers. Additionally, the device can be used to provide monitoring and protection features in systems with limited thermal management.

Key Features

The LP3470M5-2.63/NOPB offers the following key features:

• 5 channels which can sense voltage or temperature.
• Adjustable trips and adjustable delay timing for each channel.
• Diagnostic feedback for improved system reliability.
• Wide input voltage range (2.4 V to 5.5 V).
• Very low power consumption (typically 3 µA).
• High accuracy (1.5% max).
• Outputs can directly trigger power control module or generate interrupt or reset signal.

Working Principle

The LP3470M5-2.63/NOPB utilizes a proprietary architecture to provide superior performance in power management and safety applications. Its five channels can be configured for either voltage or temperature sensing, with adjustable trip points and adjustable delay timing for each channel. When a trip point or delay timing is exceeded, the device can either directly trigger a power control module or generate an interrupt or reset signal. The device also utilizes diagnostics to detect overvoltage, undervoltage, overcurrent, and overtemperature conditions and report them to the system.

The LP3470M5-2.63/NOPB also features very low power consumption and a wide input voltage range, which make it suitable for a variety of power management and safety applications. With its adjustable trips and high accuracy, the device can be tailored to meet any system’s specific requirements. In addition, the device’s outputs can be used to directly trigger a power control module or generate an interrupt or reset signal.
