# TPS2376DDA - H Product Series Introduction
## 1. Overview
The TPS2376DDA - H product series is a cutting - edge offering in the field of power management integrated circuits (PMICs). These devices are specifically designed to meet the complex power requirements of modern electronic systems, providing high - performance, reliable, and efficient power solutions. With a focus on Power over Ethernet (PoE) applications, the TPS2376DDA - H series stands out for its advanced features, robust design, and excellent compatibility with a wide range of end - user devices.
## 2. Key Features
### 2.1 PoE Compliance
- **IEEE 802.3af/at/bt Standards**: The TPS2376DDA - H series is fully compliant with the IEEE 802.3af (PoE), 802.3at (PoE+), and 802.3bt (4PPoE) standards. This ensures seamless integration with PoE - enabled networks, allowing devices to receive power and data over a single Ethernet cable. Whether it's a low - power IP camera or a high - power wireless access point, the series can support a variety of power levels required by different applications.
- **Power Classification**: It provides accurate power classification capabilities, enabling the Power Sourcing Equipment (PSE) to identify the power requirements of the Powered Device (PD) and allocate the appropriate amount of power. This helps in optimizing power distribution within the network and preventing over - or under - powering of connected devices.
### 2.2 High - Efficiency Power Conversion
- **Integrated Switching Regulators**: The devices in the TPS2376DDA - H series feature integrated switching regulators that offer high - efficiency power conversion. These regulators can step down the input voltage from the Ethernet cable to the required output voltage for the connected device, minimizing power losses and reducing heat dissipation. This not only improves the overall energy efficiency of the system but also extends the lifespan of the components.
- **Low Quiescent Current**: With a low quiescent current, the series consumes minimal power when the device is in standby or low - power mode. This is particularly important for battery - powered or energy - sensitive applications, as it helps to conserve power and increase the battery life of the connected devices.
### 2.3 Robust Protection Mechanisms
- **Over - Voltage Protection (OVP)**: The TPS2376DDA - H series is equipped with over - voltage protection to safeguard the connected device from excessive voltage on the Ethernet line. In case of a voltage spike or surge, the OVP circuit will quickly activate and limit the voltage to a safe level, preventing damage to the device.
- **Over - Current Protection (OCP)**: Over - current protection is another crucial feature of the series. It monitors the current flowing through the device and shuts off the power supply if the current exceeds a predefined threshold. This protects the device from short - circuits and other electrical faults, ensuring its reliable operation.
- **Thermal Protection**: To prevent overheating, the devices have built - in thermal protection mechanisms. When the temperature of the device exceeds a certain limit, the thermal protection circuit will reduce the power output or shut down the device temporarily until the temperature returns to a safe level.
### 2.4 Flexible Configuration
- **Adjustable Output Voltage**: The output voltage of the TPS2376DDA - H series can be easily adjusted to meet the specific requirements of different applications. This flexibility allows designers to use the same device in a variety of systems, reducing the need for multiple power management solutions.
- **Multiple Operating Modes**: The series supports multiple operating modes, such as continuous conduction mode (
