The TPS2041BDBVR is a versatile and robust power distribution switch from Texas Instruments, designed for applications where USB power distribution and precision current limiting are required. This device is part of the TPS204xB family, which is known for its enhanced system reliability and protection features.

Key Features:

• Single Channel Current-Limited Power Switch: The TPS2041BDBVR offers a single, integrated channel, making it an ideal choice for managing power to individual USB ports or other power-sensitive components.
• Programmable Current Limiting: Users can set the current limit threshold via an external resistor, allowing for tailored protection to meet specific requirements of the connected device.
• Fast Overcurrent Response: With a quick reaction to overcurrent conditions, the TPS2041BDBVR ensures that devices are protected promptly, minimizing the risk of damage.
• Thermal Shutdown Protection: The device includes an auto-recovery thermal shutdown feature that protects both the switch and the downstream devices from overheating.
• Built-in Charge Pump: The internal charge pump allows the switch to drive n-channel MOSFETs, reducing the voltage drop and power dissipation compared to p-channel MOSFETs.
• Under-Voltage Lockout (UVLO): The UVLO feature ensures that the switch remains off when the input voltage is below a certain threshold, preventing malfunctioning due to insufficient supply voltage.
• Controlled Rise Time: The TPS2041BDBVR offers a controlled rise time to reduce inrush current, which is beneficial for applications susceptible to voltage spikes.
