• Single-channel USB current limit and overvoltage protection switch
• Low-dropout voltage regulator for stable output voltage
• Integrated overvoltage protection circuit
• Compact, surface-mount package
• Wide input voltage range (4.75V to 5.5V)
• Low quiescent current (1.1µA)
• Small package size (6-pin SC-88)

Applications:

The TPS2041BD is suitable for a wide range of USB-powered devices, including:

• Smartphones and tablets
• Portable media players
• Bluetooth headsets and speakers
• Power banks and USB charging stations
• USB-to-serial adapters
• USB data acquisition systems

In summary, the TPS2041BD is a reliable and efficient solution for protecting USB-powered devices from overcurrent and overvoltage conditions. Its compact size and low quiescent current make it an ideal choice for portable and battery-powered applications.
