TPS2069CDBVT

The TPS2069CDBVT is a power management integrated circuit (IC) produced by Texas Instruments, designed primarily for power distribution applications. This device is part of the TPS206x family of power multiplexers and is particularly known for its ability to manage power supply connections efficiently.

Key Features:

1. Dual Power Switch: The TPS2069CDBVT includes two independent power switches, allowing it to control two separate power sources. This feature is particularly useful in applications where power redundancy or load sharing is required.

2. Low On-Resistance: The device boasts a low on-resistance (typically around 50 mΩ), which minimizes power loss and heat generation during operation. This characteristic is crucial for maintaining efficiency in battery-powered devices.

3. Current Limiting: The TPS2069CDBVT incorporates built-in current limiting, which protects the device and the load from overcurrent conditions. This feature is essential for preventing damage in case of short circuits or excessive load conditions.

4. Thermal Shutdown: The IC is equipped with thermal shutdown protection, which automatically disables the power switches if the junction temperature exceeds a certain threshold. This ensures safe operation and prevents overheating.

5. Logic-Controlled: The device can be controlled via logic-level inputs, making it easy to integrate into digital systems. The control pins allow for straightforward operation, enabling users to turn the switches on or off as needed.

6. Wide Supply Voltage Range: The TPS2069CDBVT operates over a wide input voltage range, typically from 2.7V to 5.5V, making it suitable for various applications, including portable devices and consumer electronics.

7. Compact Package: The IC is housed in a small, surface-mount package (DBV), which is ideal for space-constrained applications. The compact design facilitates easy integration into printed circuit boards (PCBs).

8. Applications: Common applications for the TPS2069CDBVT include power management in laptops, tablets, smartphones, and other portable devices. It is also used in USB power distribution systems and other consumer electronics where efficient power switching is required.

Electrical Characteristics:

• Input Voltage Range: 2.7V to 5.5V
• Output Current: Up to 1A per channel
