Product Overview: STMPS2161MTR by STMicroelectronics
The STMPS2161MTR from STMicroelectronics is a high-quality, single channel power distribution switch designed for applications where precision current limiting is required. This advanced device is part of the STMPS21xx product family and is specifically engineered to provide a controlled way to turn on and off the power to a load, with the added benefit of overcurrent and thermal protection.
Key Features
- Current Limiting: The STMPS2161MTR offers an accurate and programmable current limit threshold, which ensures protection against overcurrent conditions that could damage the system.
- Thermal Shutdown: With an integrated thermal shutdown feature, the device automatically turns off the output if the junction temperature exceeds the preset threshold, providing additional safety and reliability.
- Controlled Rise Time: The device ensures a controlled rise time, reducing the likelihood of inrush current at startup, which can be detrimental to both the power source and the load.
- Under Voltage Lockout (UVLO): This feature prevents the device from turning on when the input voltage is below a certain threshold, ensuring stable operation.
- Status Flag: An open-drain status flag output is available to indicate fault conditions, such as overcurrent or thermal shutdown, to the system controller.
Applications
The STMPS2161MTR is versatile and can be used in a variety of applications, including but not limited to:
- USB ports and peripherals
- Hot-swap supplies
- Power distribution switches
- Portable and battery-powered devices
Technical Specifications
With an operating voltage range of 2.7V to 5.5V, the STMPS2161MTR is suitable for low voltage applications. The switch can handle a continuous current of up to 1.5A, making it appropriate for a wide range of loads. The device is offered in a small, lead-free, RoHS-compliant SOT23-5L package, which is ideal for space-constrained applications.
