Overview
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.
