Silicon Labs Announces New Highly-Integrated PoE ICs Meeting IoT Growth Needs

Highly efficient and feature-rich Si3406x and Si3404 PD series products

For applications such as IP cameras, wireless access points, IP phones and smart lighting

Silicon Labs (also known as "Core Technology") has released two new Power over Ethernet (PoE) powered device (PD) series products to provide first-class integration and efficiency for a variety of Internet of Things (IoT) applications. Silicon Labs' Si3406x and Si3404 series products include all necessary high-voltage discrete components on a single PD chip.

The rapid expansion of IoT is driving the need for PoE+ connectivity in applications such as IP cameras, smart lighting fixtures, feature-rich video IP phones, advanced 802.11 wireless access points, and smart home appliances. These higher power applications require increased demand for PD devices that support the PoE+ standard. For example, the latest motor positioning IP cameras with pan/tilt/zoom and heating elements can cause severe power loads. PoE+ technology delivers 30 watts of output power to support these demanding application tasks. Silicon Labs' Si3406x family is ideal for residential, commercial and industrial environments and is the ideal PD interface solution for new PoE+-enabled IoT products.

Ross Sabolcik, vice president of power products at Silicon Labs, said: "Silicon Labs' PoE solution offers a variety of power levels up to 30 watts to meet the demanding power requirements of our customers. Our PD portfolio brings industry-leading integration and advanced features. Helps developers simplify design while meeting their power consumption and cost budgets Silicon Labs' one-stop PoE products address both applications at both ends of an Ethernet cable, including a new PD device, PSE controller and PSE power supply Management IC."

Complementing the Si3406x family, the Si3404 IC offers a cost-effective 802.3 Type 1 compliant product for low power 15W PoE PD applications. The Si3404 integrates all interface and control functions required for low-power PD applications in a very small package.

Si3406x IC Set

The integrated synchronous driver can control the secondary side field effect transistor (FET) to improve the power conversion efficiency. Maintains the connection with the PSE switch in sleep mode with the Automatic Maintenance Power Signature (MPS) feature.

The Si3406x family of current-mode controlled switching regulators supports a variety of isolated and non-isolated power supply topologies. The regulator is supplemented by an integrated power switch FET. This flexibility, along with Silicon Labs' complete PoE PD reference design, makes it easier for developers to deploy key power subsystems.
