概述

Description

TPS2413D is TI’s hot‑swap current‑limit controller. It protects a power rail during board insertion or fault by driving an external N‑channel MOSFET to limit inrush and overcurrent.
How it works: it senses load current via a sense resistor and clamps the MOSFET gate to achieve a defined current‑limit with a soft‑start, reducing inrush. It also provides protections and control signals, such as undervoltage lockout and an enable input.
Key features (typical): adjustable current‑limit (via external resistor), soft‑start to control turn‑on, undervoltage and overcurrent protections, and an enable/shutdown control. External components required: MOSFET, sense resistor, and proper gate drive/layout.
Applications: hot‑plug systems like backplanes, servers, storage, and telecom equipment where boards are inserted/removed.
Note: exact specs, pinout, and package options vary by variant. Check the TPS2413D datasheet and TI resources for precise details.

Features

- One-channel hot-swap controller for safe board insertion/backplane operation
- Requires an external N-channel MOSFET as the high-side pass element
- Inrush current control with soft-start to limit dv/dt
- Programmable current limit via sense resistor
- Undervoltage lockout (UVLO) with hysteresis for reliable startup
- Overcurrent/short-circuit protection, often with latch and retry
- Overvoltage/transient protection and input fault handling
- Thermal shutdown with latch and automatic retry
- Enable input to force on/off; fault/status signaling (status/FLT output)
- Compact packaging options suitable for backplane/telecom/applications
Note: For exact electrical values, pinout, and package details, refer to the TPS2413D datasheet.

Package

TPS2413D is available in an 8-pin D‑package, i.e., an 8‑pin SOIC package.

Pinout

- Pin count: 8 pins (8-pin package such as SOIC/MSOP).
- Function: TPS2413D is a single high‑side load switch with enable control, providing current‑limit protection and thermal protection to switch power from Vin to Vout for a load (hot‑swap/power‑distribution protection).

Manufacturer

- Manufacturer: Texas Instruments (TI).
- What kind of company: An American multinational semiconductor company that designs and manufactures analog, mixed-signal, and embedded processing integrated circuits.

Application

TPS2413D is a high-side protection switch with current limit and thermal shutoff for hot-swap protection. Typical applications: hot-swap/inrush protection for power rails in servers, telecom and networking equipment; DC distribution and backplanes; protection for point-of-load regulators in automotive/industrial gear; and battery-powered devices needing overcurrent/short-circuit protection.
