Frequently Asked Questions
What is the supply voltage range for the TPS23851DCE?
The TPS23851DCE operates from a 44V to 57V supply voltage range, corresponding to the IEEE 802.3af/at PoE standard voltage requirements for Power Sourcing Equipment. This range ensures compatibility with standard PoE power supplies and midspans used in enterprise and industrial network infrastructure.
What package does the TPS23851DCE use and how many pins does it have?
The TPS23851DCE is packaged in a 36-pin SSOP (Shrink Small Outline Package) with 0.4 mm pin pitch (JESD-30 Code: R-PDSO-G36). This compact surface-mount package supports high-density PCB layouts and is suitable for multi-port PoE controller designs in space-constrained network equipment enclosures.
What interface does the TPS23851DCE use for control and monitoring?
The TPS23851DCE uses an I2C serial interface for communication with a host microcontroller or system management bus (SMBus). This allows real-time monitoring of port current, voltage, and power status, as well as programmable control of port enable/disable, power classification, and fault management functions.
What are typical applications for the TPS23851DCE?
The TPS23851DCE is used in PoE-capable Ethernet switches, wireless LAN access points, IP surveillance cameras power hubs, VoIP telephone systems, and industrial Ethernet controllers. It is particularly suited for Power Sourcing Equipment (PSE) requiring multi-port PoE management with I2C-based system integration.
Is the TPS23851DCE RoHS compliant?
The TPS23851DCE has a Pb-free code of No, indicating it uses a standard tin-lead solder finish rather than a lead-free finish. Designers should verify RoHS compliance requirements for their target market and consider available lead-free alternatives if the application demands full RoHS conformance.
