概述

Description

TPS2514ADBVR is a Texas Instruments four-channel hot‑swap controller. It protects multiple power rails during hot‑plug events (insertion/removal) and fault conditions by driving external N‑channel MOSFETs and limiting inrush current. Each channel provides current‑limit/overcurrent protection, as well as fault and status signaling, helping to prevent damage from shorts or power surges on a live supply. The device is typically used to guard rails in servers, backplanes, telecom equipment, and other multi‑rail systems that require safe hot‑swapping.
Key points:
- Four independent channels with current limit and fault outputs
- External MOSFETs required; external sense resistor used to set limit
- protections: overcurrent/short‑circuit, undervoltage/overload, and fault/status indication
- Package: DBV (VSSOP‑16 style), RoHS, tape & reel under the ADBVR designation
In short, TPS2514ADBVR is a multi‑channel hot‑swap protection IC for safely managing multiple live power rails.

Features

TPS2514ADBVR features (concise):
- Four high-side load switches for concurrent channel control
- Independent enable control for each channel
- Adjustable current limit per channel (external resistor)
- Overcurrent protection with hiccup behavior
- Overvoltage and undervoltage lockout
- Thermal shutdown protection
- Reverse-battery protection and reverse-current blocking
- Output discharge when switching outputs off
- Fault/diagnostic indication (status/fault signaling)
- Suitable for automotive and general power-management applications
- Small package with tape-and-reel (ADBVR) packaging option

Package

TPS2514ADBVR uses the DBV package, i.e., an 8-pin VSSOP (Very Small Outline Package) package (about 3×3 mm).

Pinout

- Pin count: 20 pins (DBVR package)
- Function: 4-channel high-side power-distribution switch with per-channel current limit, protection (overcurrent/short-circuit), soft-start, and I2C-compatible control for enabling/disabling each channel. Includes fault/status reporting.

Manufacturer

- Manufacturer: Texas Instruments (TI).
- What kind of company: A global American semiconductor company that designs and manufactures analog, mixed-signal, and power-management ICs (and other semiconductor products) for electronics.

Application

- Hot-swap control with inrush limiting for DC power rails
- Overcurrent/short-circuit protection
- Overvoltage and thermal protection
- Power-up/power-down sequencing for multi-rail systems
- Reverse-current protection and safe shutdown
- Suitable for servers, telecom/network equipment, industrial controllers, and consumer electronics with removable modules
