Overview of Texas Instruments TPS2061CDBVR
The TPS2061CDBVR from Texas Instruments is a robust, high-performance, single-channel USB power distribution switch optimized for USB and other hot-swap applications. This compact and efficient device is designed to provide precise current limiting to protect the host device from over-current conditions typically found in fault situations.
Key Features
- Current Limiting: The TPS2061CDBVR offers an adjustable current limit, which can be set by an external resistor. This feature ensures that the USB port does not exceed its current capacity, thus safeguarding both the USB host and the connected devices.
- Thermal Shutdown: With an integrated thermal shutdown feature, the device protects itself and the connected peripherals from damage due to excessive heat by automatically turning off when the junction temperature exceeds the thermal shutdown threshold.
- Under-Voltage Lockout (UVLO): The UVLO feature ensures that the switch remains off when the input voltage falls below a specified threshold, preventing malfunctioning due to insufficient supply voltage.
- Fast Transient Response: The device is designed to handle fast transients on the bus line, which is essential for maintaining stable operation in fluctuating power environments.
- Controlled Rise Time: The TPS2061CDBVR has a controlled output rise time which reduces inrush current, thereby minimizing the stress on the host power supply during hot-plug events.
Applications
The versatility of the TPS2061CDBVR makes it suitable for a wide range of applications, including:
- USB hubs and peripherals
- Hot-swap power supplies
- Battery-charger circuits
- Power distribution switches
Package and Reliability
The TPS2061CDBVR is offered in a compact SOT-23-6 package, which is ideal for space-constrained applications. Its small footprint does not compromise on reliability, as the device is designed and tested to meet the rigorous standards set by Texas Instruments for power management circuits.
In summary, the TPS2061CDBVR is an excellent choice for designers looking for a power distribution switch that combines protection features, reliability, and a small form factor, making it an invaluable component in USB power management and other hot-swap applications.
