TPS2065D

The TPS2065D is a power management integrated circuit (IC) produced by Texas Instruments, designed primarily for power distribution applications. It is part of the TPS206x family, which is known for its high-performance power switch capabilities. Here’s a detailed description of the TPS2065D:

General Overview

The TPS2065D is a dual power switch that provides a controlled power path for powering devices in various applications, such as USB power distribution, battery management systems, and other portable electronics. It is designed to handle high current loads while ensuring safe operation and efficient power management.

Key Features

1. Dual Power Switch: The TPS2065D includes two independent power switches, allowing it to control two separate power paths. This feature is particularly useful in applications where multiple devices need to be powered from a single source.

2. Current Rating: The device can handle a continuous output current of up to 2A per channel, making it suitable for powering a variety of peripherals and devices.

3. Low On-Resistance: The TPS2065D features a low on-resistance (typically around 100 mΩ), which minimizes power loss and heat generation during operation, enhancing overall efficiency.

4. Thermal Protection: The IC includes built-in thermal shutdown protection, which prevents damage to the device and the connected load in case of overheating.

5. Overcurrent Protection: The TPS2065D is equipped with overcurrent protection features that help to safeguard both the IC and the load from excessive current conditions. This is crucial for preventing damage in fault conditions.

6. Reverse Current Protection: The device prevents reverse current flow, ensuring that power does not back-feed into the power source, which can be critical in battery-powered applications.

7. Enable Control: The TPS2065D has an enable pin that allows for easy control of the power switches. This feature enables the user to turn the power on or off as needed, facilitating power management in the system.

8. Compact Package: The IC is available in a small, surface-mount package (such as the HTQFN), which is ideal for space-constrained applications.

Electrical Characteristics

• Input Voltage Range: The TPS2065D typically operates within a voltage range of 2.7V to 5.5V, making it compatible with standard logic levels and power sources.
• Quiescent Current: The device has a low quiescent current, which is beneficial for battery-operated devices, as it helps to extend battery life.
