TPS2066CD

The TPS2066CD is a power management integrated circuit (IC) produced by Texas Instruments, designed primarily for power distribution applications. It is a dual-channel power switch that provides controlled power distribution to various loads, making it ideal for use in portable devices, consumer electronics, and other applications where power management is critical.

Key Features:

1. Dual Power Switch: The TPS2066CD contains two independent power switches, allowing it to control two separate power paths. This feature is particularly useful in applications where multiple power sources or loads need to be managed.

2. Low On-Resistance: The device boasts a low on-resistance (typically around 100 mΩ), which minimizes power loss and heat generation during operation. This characteristic enhances efficiency, especially in battery-powered applications.

3. Current Limiting: The TPS2066CD includes built-in current limiting functionality. This feature protects the device and the connected loads from overcurrent conditions, ensuring safe operation and preventing damage.

4. Thermal Shutdown: To further enhance reliability, the IC is equipped with thermal shutdown protection. If the junction temperature exceeds a certain threshold, the device will automatically turn off to prevent overheating.

5. Logic-Controlled Operation: The power switches are controlled by logic-level inputs, making it easy to interface with microcontrollers or other digital logic devices. This allows for straightforward control of the power distribution based on system requirements.

6. Wide Supply Voltage Range: The TPS2066CD operates over a wide input voltage range, typically from 2.7V to 5.5V, making it versatile for various applications.

7. Compact Package: The IC is available in a compact surface-mount package (such as the TSSOP-16), which is suitable for space-constrained designs. This small footprint allows for easy integration into printed circuit boards (PCBs).

8. Applications: Common applications for the TPS2066CD include USB power distribution, battery-powered devices, portable electronics, and any system requiring efficient power management and distribution.

Electrical Characteristics:

• Input Voltage Range: 2.7V to 5.5V
• Output Current: Up to 1A per channel
• On-Resistance: Typically 100 mΩ
• Current Limit: Adjustable or fixed, depending on the configuration
• Operating Temperature Range: -40°C to +85°C

Conclusion:
