STMPS2171TTR Power Switch IC by STMicroelectronics

The STMPS2171TTR from STMicroelectronics is a high-quality, single-channel power switch IC designed for USB and other hot-swap applications. This compact and efficient integrated circuit is housed in a small, surface-mount package, making it an excellent choice for space-constrained designs.

Key Features:

• Current Limiting: The STMPS2171TTR provides precise current limiting to protect the host device from over-current conditions. This feature ensures safe operation for both the IC and the connected peripheral devices.
• Thermal Shutdown: With an integrated thermal shutdown mechanism, the device automatically turns off in the event of overheating, thereby preventing thermal damage.
• Controlled Rise Time: The IC offers a controlled output voltage rise time, which reduces inrush current and minimizes the risk of voltage spikes that could potentially harm connected components.
• Under-Voltage Lockout (UVLO): The under-voltage lockout feature ensures that the switch remains off if the input voltage drops below a certain threshold, thereby protecting the circuit.

Applications:

The STMPS2171TTR is versatile and can be used in a variety of applications, including:

• USB power management
• Hot-swap power control
• Portable and battery-powered devices
• Peripheral power control

Technical Specifications:

• Package: SOT23-5
• Operating Voltage Range: 2.7V to 5.5V
• Continuous Current: Up to 0.5A
