Hot Swap Controllers

UCC2919DTRG4 Description

The UCC2919DTRG4 is a General Purpose Hot Swap Controller designed by Texas Instruments. This single-channel controller is engineered to manage the insertion and removal of circuit boards in live systems, ensuring reliable operation and protection against voltage and current anomalies. The UCC2919DTRG4 operates within a supply voltage range of 3V to 8V and draws a supply current of just 1 mA, making it highly efficient for a variety of applications.

This controller is packaged in a Surface Mount Tape & Reel (TR) format, which is ideal for automated assembly processes and ensures high reliability in manufacturing. The UCC2919DTRG4 is also compliant with REACH and ROHS3 standards, ensuring it meets environmental and safety regulations. With a Moisture Sensitivity Level (MSL) of 2, it is suitable for storage conditions up to 1 year.

UCC2919DTRG4 Features

The UCC2919DTRG4 offers several unique features that enhance its performance and reliability:

• UVLO (Under-Voltage Lockout): This feature ensures the controller remains inactive when the supply voltage falls below a safe operating threshold, preventing damage to the system.
• Programmable Features: The UCC2919DTRG4 includes programmable Auto Retry, Circuit Breaker, Current Limit, Fault Timeout, and Latched Fault mechanisms. These features provide robust protection and flexibility in managing fault conditions.
• No Internal Switches: The absence of internal switches allows for a more streamlined design and reduces the risk of internal failures.
• General Purpose Applications: The UCC2919DTRG4 is versatile and can be used in a wide range of applications where hot swap functionality is required.
