Overview
The UCC2919DG4 is a single-channel hot-swap voltage controller manufactured by Texas Instruments. It operates within a supply voltage range of 3 V to 8 V and draws a typical operating supply current of 1 mA. The device is designed for industrial temperature applications, supporting an operating range from -40°C to +85°C. It is housed in a 16-pin SOIC package with a width of 0.154 inches (3.90 mm). The component includes undervoltage lockout (UVLO) features and is RoHS compliant.
Feature Summary
- Provides comprehensive protection against overcurrent conditions through programmable limit control and fault timeout mechanisms.
- Supports automatic system recovery after fault clearance via integrated auto-retry functionality.
- Ensures controlled power-up sequencing to prevent bus collapse during insertion or removal events.
Applications
- General-purpose circuit board insertion and removal protection
- Industrial equipment backplane power management
- Telecommunications infrastructure card protection
Procurement Notes
Verify the specific suffix designation carefully, as the UCC2919 family has undergone end-of-life notifications. Confirm availability status with authorized distributors, as original manufacturing may be discontinued. Ensure that any replacement components meet the same electrical specifications and thermal requirements for your specific application design.
Selection Notes
Select this controller when designing systems requiring robust protection for single-rail hot-swap applications. Consider the 3 V to 8 V input range compatibility with standard logic levels. Evaluate the need for auto-retry features versus latching fault protection based on system reliability requirements and maintenance protocols.
Part Context
This component belongs to the UCC2919 series of hot-swap controllers from Texas Instruments. It is part of the broader PMIC category focused on power management and switching controls. The device is distinct from audio amplifiers or general logic gates found in other semiconductor listings.
Replacement Considerations
Public confirmed substitute: TPS24700DGK
FAQ
Does the UCC2919DG4 include an internal switch?
No, the UCC2919DG4 is a controller without an internal switch; it requires an external N-channel MOSFET for power path control.
What is the maximum operating temperature for this device?
The maximum operating temperature is +85°C, suitable for industrial environment applications.
