Présentation

Description

TPS2561ADRCR is a Texas Instruments single-channel hot-swap switch (high-side power switch) used to protect a power rail during insertion, inrush, and fault events. It limits inrush current and provides overcurrent protection to safeguard downstream circuitry. Key features typically include current limit, soft-start to control ramp, enable input, fault/status output, and thermal shutdown with auto-retry. The ADRCR suffix denotes the device’s RoHS, lead-frame/package style (8-pin). Common applications are protecting supply rails in servers, telecom equipment, embedded boards, USB/PCIe adapters, and other systems requiring safe hot-swap and inrush protection.

Equivalent

TPS2561ADRCR is TI's high-side load switch with ~1 A current limit, reverse-current blocking, and enable. There isn't a direct, exact cross-reference. Closest equivalents: other TPS2561 package variants; other vendors' high-side load switches with similar current rating and enable, e.g., Onsemi NCP-series and STMicroelectronics power-distribution switches. For exact cross-reference, use TI Cross Reference or distributor search against ADRCR packaging.

Features

TPS2561ADRCR features:
- 1-channel high-side power distribution switch
- Built-in overcurrent/short-circuit protection with current-limit
- Thermal shutdown protection
- Reverse-current protection
- Enable (on/off) control input
- Inrush/soft-start to limit surge current
- Low on-resistance MOSFET for efficiency
- Small 8-pin package (ADRCR variant) suitable for compact designs
- Typically operates in low-voltage ranges suitable for USB/battery-powered systems
Note: Always refer to the datasheet for exact electrical specs and pinout.

Pinout

Pin count: 8 pins (DCR package).
Function: TPS2561ADRCR is an 8‑pin high-side power-distribution switch with current-limit and protection. It provides VIN-to-VOUT power path control with enable input and fault/status signaling; the current limit is set externally (ILIM) and it includes overcurrent protection.

Manufacturer

Manufacturer: Texas Instruments Incorporated (TI).
What kind of company: TI is an American multinational semiconductor company that designs and manufactures analog and mixed-signal integrated circuits, embedded processors, and related semiconductor products; one of the world's largest semiconductor makers, headquartered in Dallas, Texas.

Application

TPS2561ADRCR is a high-side switch with hot‑swap control, current limiting and fault protection. Common applications include:
- Hot‑swap protection for DC rails in servers, storage, networking, and telecom backplanes.
- Soft‑start and current limiting for CPUs/GPUs/FPGA/ASIC power rails.
- Inrush control for desktops, industrial controllers, and embedded systems.
- Power-distribution protection in industrial automation and robotics.
- Protection for battery-powered equipment requiring short-circuit/fault protection.

Package

TPS2561ADRCR is in an 8-pin WSON package (3×3 mm) with an exposed pad; Pb-free/RoHS compliant.
