Description

TPS2419PWR is TI’s single-channel high‑side hot‑swap controller with protection for a power rail. It drives an external MOSFET to protect a load during insertion or fault conditions.
Key features
- Inrush current limiting and soft-start to reduce voltage spike
- Overcurrent protection (with latching) and thermal protection
- Undervoltage lockout
- Fault/status signaling (open-drain output)
How it’s used
- Placed between the supply and the load; the device controls the external MOSFET gate
- Sets current limit via an external sense resistor and programming network
- Disables the pass element on fault and asserts the status signal
Applications
- Hot-swappable backplanes, server and telecom power rails
- Storage drives, network equipment, and other systems requiring controlled inrush and protection
Package note
- PWR suffix indicates TI’s Power/8-pin package variant
In short, TPS2419PWR provides controlled inrush, overcurrent/thermal protection, and fault signaling for reliable power-rail protection with an external MOSFET.

Features

Key features of TPS2419PWR (hot-swap/high-side switch controller in PowerPAD package):
- External MOSFET drive: drives a high-side N-channel FET to handle load current with controlled inrush.
- Wide input range: suitable for 4.5–28 V common power rails (automotive-ready).
- Adjustable current limit: settable via sense resistor for protection against short circuits.
- Slew-rate controlled turn-on: limits inrush current to protect the power rail and backplane.
- Enable input: allows turning the device on/off under logic control.
- Overcurrent/short-circuit protection: fast trip to safeguard downstream circuitry.
- Overvoltage protection and undervoltage lockout: guards against abnormal supply conditions.
- Thermal shutdown: protects against overheating with automatic recovery.
- Fault/Status signaling: status output (and/or fault indication) for system monitoring.
- Thermal performance: PowerPAD exposed pad for improved heat dissipation.

Package

The TPS2419PWR is in an 8-pin VSSOP (Very Small Outline Package) package.

Pinout

- Pin count: 8 pins (8-pin package).
- Function: TI TPS2419PWR is a high-side hot‑swap controller with current limiting. It drives an external MOSFET to limit inrush and provide overcurrent protection for a power rail, protecting the system during plug-in and fault conditions.

Manufacturer

The TPS2419PWR is manufactured by Texas Instruments Incorporated (TI). TI is an American multinational semiconductor company that designs, manufactures, and sells analog, mixed-signal, and embedded processing integrated circuits. It is headquartered in Dallas, Texas and is publicly traded (NASDAQ: TXN).

Application

- Hot-swap protection and current limiting for DC rails
- Used in servers, data centers, and backplanes
- Telecom and networking equipment (switches/routers)
- Industrial automation and motor control
- Power-distribution units and blade/server architectures
