SI3402-B Overview
Description
Point-of-sale terminals - Internet appliances - Network devices - High power applications The Si3402 integrates all power management and control functions required in a Power-over-Ethernet (PoE) powered device (PD) application. The Si3402 converts the high voltage supplied over the 10/100/1000BASE-T Ethernet connection into a regulated, low-voltage output supply.
Key Features
- Pin-compatible replacement for the obsolete Si3402-A
- IEEE 802.3 standard-compliant solution, including pre-standard (legacy) PoE support
- Highly-integrated IC enables compact solution footprints
- Minimal external components
- Integrated diode bridges and transient surge suppressor
- Integrated switching regulator controller with on-chip power FET
- Integrated dual current-limited hotswap switch
- Programmable classification circuit
- Incorporates switcher EMIreduction techniques
- Supports non-isolated and isolated switching topologies
