概要

Description

TPS24740RGER is TI’s single-channel high-side switch with built-in protection for hot-swapped power rails. It acts as a controllable power path between the input supply and the load, turning on/off under an enable control and safeguarding downstream circuitry.
Key features (high level):
- Programmable current limit (ILIM) via external resistor
- Inrush control on turn-on
- Overcurrent/short-circuit protection (with fault indication)
- Overtemperature protection (thermal shutdown)
- Reverse-current protection
- Enable input and undervoltage lockout
- Fault/status output to a host MCU
- RoHS-compliant RGER package (8-pin)
Typical uses:
- Safe power-up/down and protection for processors, memory, FPGAs, telecom/data-center rails, and other loads requiring hot-swap protection and rail integrity.
For exact electrical specs, package detail, and application guidance, refer to the TPS24740RGER datasheet.

Features

Here are the key features of the TPS24740RGER (TI hot-swap/load switch):
- 40-V rated high-side switch with integrated MOSFET
- Programmable current limit via external ILIM resistor (Itrip)
- Overcurrent/short-circuit protection with auto-retry
- Overvoltage protection and undervoltage lockout
- Thermal shutdown protection
- Reverse-polarity protection
- Enable input to turn the switch on/off
- Fault/Status signaling (FLT/STAT) with open-drain output
- Soft-start to limit inrush current
- Hot-swap/load-disconnect capability for safe board-level protection
Ideal for protecting and sequencing power rails in complex boards (battery, automotive, industrial).

Package

TPS24740RGER is in a VQFN-16 package (3x3 mm) with an exposed pad; RoHS/lead-free.

Pinout

- Pin count: 16 pins (16‑pin package, e.g., VSON/TSSOP variant for TPS24740RGER).
- Function: Single‑channel high‑side power distribution switch (hot‑swap controller) with current‑limit protection, soft‑start, enable input, and fault/status diagnostics (overcurrent/short‑circuit and thermal protection).

Manufacturer

- Manufacturer: Texas Instruments (TI)
- What kind of company: A global semiconductor company that designs and manufactures analog, digital, and mixed-signal integrated circuits and related semiconductor products.

Application

TPS24740RGER is a multi‑channel hot‑swap controller used to protect boards during insertion/removal and limit fault currents. Typical applications: backplane/daughterboard hot‑swap protection in servers, data centers, telecom and network equipment; multi‑rail power supplies (PCIe, etc.); front‑end power protection with inrush limiting and soft‑start; industrial control/automation equipment; and short‑circuit/overcurrent protection with fault isolation across rails in distributed power architectures.

Equivalent

TPS24740RGER is TI’s four-channel hot-swap switch with current limit and fault protection. The closest TI equivalents are other devices in the TPS2474x family (same core, different channel options/features). For cross-vendor equivalents, exact matches depend on your specs. Please share required current per channel, total channels, and package to get precise cross-references.
