The LM5070SD-50/NOPB is an application field and power over Ethernet (PoE) controller. It’s an advanced single-phase PoE controller that is capable of providing both auxiliary power in addition to PoE power. The device can draw up to 25W of power from a powered device (PD) and allows up to 9 classes of PDs to be identified and serviced. The device can be integrated directly into a variety of systems such as switches and routers.

The LM5070SD-50 can detect the device’s power requirements quickly and efficiently, allowing the PD’s maximum power draw to be efficiently allocated. This power is distributed to the PD using a 4-pair voltage mode architecture. The device also monitors and controls the delivery of power to ensure its safe and efficient distribution. This helps to maintain a constant power supply for the PDs and also helps to protect the network from overloading and potential damages.

The LM5070SD-50 offers sophisticated protection and control including surge protection, current-limiting, over-current protection, over temperature protection and short circuit protection. The device features a wide operating temperature range of -40°C to 100°C and is rated for up to 35W output power. It is designed to meet IEEE 802.3af standards, which makes the device compatible with a wide range of PDs.

The LM5070SD-50 is available in a 34-pin 6x6mm quad flat no-lead (QFN) package, which is designed to reduce power losses and increase power efficiency. The device can be easily integrated into existing and new systems, allowing manufacturers to significantly reduce the complexity of designs. It also offers enhanced design flexibility and scalability, enabling manufacturers to quickly and easily reduce their costs.

The device is easy to operate and can be easily configured and monitored using an I2C interface. The device also feature a low standby power and high efficiency mode, reducing power consumption and helping to conserve energy. The LM5070SD-50 is an ideal solution for PoE applications and helps to reduce costs, complexity and electrical risks.
