The STMPS2161STR from STMicroelectronics is a sophisticated, integrated power switch designed for USB and other hot-swap applications. This device is housed in a compact TSOT23-5 package, making it an excellent choice for space-constrained designs. It is engineered to provide a high level of protection to systems and loads that can be subjected to high current conditions.

Key Features

• Overcurrent Protection: The STMPS2161STR offers precise overcurrent protection to prevent damage to your connected devices, ensuring reliable operation and extending product life.
• Thermal Shutdown: With built-in thermal shutdown, the device protects itself and the system from overheating, which can occur during high current draw or fault conditions.
• Current Limiting: The device features an adjustable current limit, allowing designers to set a maximum current threshold to match the requirements of their specific application.
• Controlled Rise Time: The controlled rise time reduces inrush current, which can be particularly useful in preventing nuisance trips when powering capacitive loads.
• Under-Voltage Lockout (UVLO): The UVLO feature ensures that the device operates at the correct voltage levels, protecting both the power switch and the load from undervoltage conditions.

Applications

The STMPS2161STR is versatile and can be used in a variety of applications, including:

• USB-powered devices and USB hubs
• Hot-swap power supplies
• Peripheral ports
• Battery-charger ports
