The TPS2552DBVR and TPS2552DBVT, part of Texas Instruments' power management portfolio, are state-of-the-art precision adjustable current-limited power-distribution switches designed for applications requiring fine tuning of current limits in USB and other hot-swap applications.

These devices offer a programmable current limit threshold between 0.75 A and 2.9 A (typical) via an external resistor. This feature allows for precise control of the power distribution to downstream circuits, providing protection against overcurrent conditions and improving system reliability. The TPS2552 series is particularly well-suited for USB applications where precise current limiting can help to prevent damage to USB ports and connected devices.

The TPS2552DBVR and TPS2552DBVT are available in small, space-saving 6-pin SOT-23 (DBV) and 6-pin SON (DCT) packages, respectively. This compact form factor makes them ideal for portable applications where space is at a premium. The switches also feature a fast transient response time and built-in thermal shutdown protection, further safeguarding the system from damage due to overcurrent and overheating events.

Key features of the TPS2552 series include:

• Adjustable Current-Limit Threshold via External Resistor
• Reverse Current Blocking when Power is Switched Off
• Under-Voltage Lockout (UVLO)
• Over-Temperature Protection
• Fast Transient Response
• Low Quiescent Current
• Controlled Slew Rate to Reduce Inrush Current

These devices are versatile and can be used in a variety of applications beyond USB power distribution, including battery charging and management, hot-swap power supplies, and adjustable current-limited power rails in industrial and consumer electronics.

With the TPS2552DBVR and TPS2552DBVT, Texas Instruments continues to demonstrate its commitment to providing innovative solutions for power management challenges. These switches are designed to enhance system safety and efficiency, making them a valuable addition to any power-sensitive application.
