TPS2555DRCT Description

The TPS2555DRCT from Texas Instruments is a high-side, N-channel power distribution switch designed for general-purpose load switching applications. This single-channel IC operates within a 4.5V to 5.5V load voltage range and delivers a maximum output current of 2.5A, making it ideal for USB power management, portable devices, and hot-swap applications. The device integrates a low 73mOhm (typical) Rds(on) MOSFET, minimizing power dissipation and improving efficiency. It requires no external supply voltage (Vcc/Vdd), simplifying system design. Packaged in a compact 10-VSON (DRC) tape-and-reel (TR) format, it is optimized for surface-mount assembly and complies with RoHS3 and REACH environmental standards.

TPS2555DRCT Features

• Adjustable Current Limiting: Protects downstream circuits from overcurrent conditions.
• Integrated Fault Protections: Includes over-temperature shutdown and undervoltage lockout (UVLO) for robust operation.
• Status Flag Output: Provides real-time fault indication (e.g., overcurrent or thermal shutdown).
• Low Quiescent Current: Enhances power efficiency in battery-operated systems.
• Wide Operating Voltage (4.5V–5.5V): Suitable for 5V bus applications like USB 2.0/3.0.
• 1:1 Input-to-Output Ratio: Ensures minimal voltage drop across the switch.
• MSL2 (1-Year Floor Life): Ensures reliability in storage and handling.

TPS2555DRCT Applications

• USB Power Switching: Protects host devices from short circuits in peripherals.
• Portable Electronics: Power management in smartphones, tablets, and wearables.
• Hot-Swap Systems: Enables safe insertion/removal of boards in servers and industrial controllers.
• Battery-Powered Devices: Efficient load switching in IoT sensors and wireless modules.
• Automotive Accessories: Auxiliary power distribution in infotainment systems.

Conclusion of TPS2555DRCT

The TPS2555DRCT stands out for its low Rds(on), integrated protections, and compact form factor, making it a superior choice for space-constrained, high-efficiency designs. Its adjustable current limiting and status monitoring provide flexibility and diagnostics, while its 5V compatibility ensures broad applicability. Engineers will benefit from its simplified design integration and enhanced reliability in demanding environments. Ideal for consumer, industrial, and automotive applications, this power switch delivers performance, safety, and cost-effectiveness in a single package.
