Product Overview: Texas Instruments TPS2041CDBVT

The TPS2041CDBVT is a high-quality, single-channel, current-limited, power distribution switch designed by Texas Instruments for applications where precision current limiting is required. This device is part of the TPS204x family and is housed in a compact SOT-23-6 package, making it an ideal choice for space-constrained applications.

With an input voltage range of 2.7V to 5.5V, the TPS2041CDBVT is perfectly suited for a variety of USB-powered devices and other portable electronics. The switch provides a continuous current of 500mA, which can be adjusted by an external resistor, allowing for customization based on specific design requirements.

Key Features

• Current Limiting: The TPS2041CDBVT offers accurate and adjustable current limiting to protect the host device from overcurrent conditions.
• Thermal Shutdown: The device includes a thermal shutdown feature that protects against excessive power dissipation and junction temperatures.
• Under-Voltage Lockout (UVLO): Ensures that the switch remains off when the input voltage is below a certain threshold, preventing malfunctioning due to undervoltage conditions.
• Fast Transient Response: The device is capable of responding quickly to changes in load conditions, ensuring stable operation.
• Controlled Rise Time: The TPS2041CDBVT minimizes inrush current during power-up, contributing to the overall system reliability.
• Reverse Current Protection: This feature prevents current from flowing backward through the switch when it is powered off.
• Low Standby Current: The low power consumption in standby mode makes it an energy-efficient choice for battery-powered applications.
