Overview

Description

TPS23880RTQR is a Texas Instruments hot‑swap controller (TPS23880 family) used to safely power up and protect a system rail. It controls an external pass element (MOSFET) to limit inrush current and provides protection during fault conditions. Typical features include current limiting, overcurrent protection, overvoltage protection, undervoltage lockout, thermal shutdown, and a fault/status output to indicate a problem. RTQR denotes Tape & Reel packaging for manufacturing. Common applications are telecom/network equipment, data storage, and industrial systems where controlled hot‑swap insertion and rail protection are required. Note that you still need an external MOSFET and sense resistor, plus proper PCB layout per TI guidelines. For exact electrical specs and pinout, consult the TPS23880 datasheet and packaging description.

Features

TPS23880RTQR features (concise):
- IEEE 802.3af/at PoE PD interface controller (Type 1 and Type 2 support)
- Integrated high‑voltage switch for the PD power path (no external FET required)
- PoE detection, classification and power negotiation support
- Wide input (PoE) range ~44–57 V with surge/ESD protection
- Inrush control and soft‑start for safe cable connection
- Robust protection: overcurrent/short‑circuit, overvoltage, reverse polarity
- Undervoltage lockout and thermal shutdown protection
- Status/diagnostic outputs for PD present, fault, and power good
- Low quiescent current and suitable for high-efficiency designs
- Small package (QFN/VSON family) with RTQR tape‑and‑reel packaging
Note: Refer to the datasheet for exact electrical specs, programming options, and pinout.

Package

8-pin VSSOP (Very Small Outline Package).

Pinout

- Pin count: 8 pins (8-pin package, e.g., VSSOP/TSSOP).
- Function: PoE PD interface controller for IEEE 802.3af/at; handles PD detection, classification, current limiting, and protections, and provides gate drive/control for the external MOSFET to connect/disconnect the PoE input.

Manufacturer

The TPS23880RTQR is manufactured by Texas Instruments (TI). TI is an American multinational semiconductor company that designs and manufactures a broad range of integrated circuits and analog/digital semiconductors used in electronics worldwide.

Application

TPS23880RTQR is a high‑voltage hot‑swap protection and current‑limit switch. Typical applications:
- Servers, storage, and telecom power supplies
- Industrial control/backplanes and DC power distribution
- Battery chargers and power adapters
- Automotive and motor/equipment power electronics
- Any system needing overcurrent/short‑circuit protection on a high‑side rail

Equivalent

TPS23880RTQR is TI’s hot-swap controller with current limit and fault protection. There isn’t a single exact cross‑vendor equivalent. Functional matches include TI’s own TPS23840/TPS23860 (same family) and other vendors’ hot‑swap controllers with current limit, such as Analog Devices ADM1180/ADM1170 and Onsemi NCP4300/NCP4306. For exact cross-reference, use TI’s Cross Reference tool with your required current rating and package.
