Overview
The UCC2919PW 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 current of 1 mA. Designed for industrial applications, the device functions reliably across an extended temperature range from -40°C to +85°C. The component is housed in a 16-pin TSSOP surface-mount package with a width of 4.40 mm. It integrates essential protection features including under-voltage lockout (UVLO), programmable soft-start, current limiting, and fault timeout mechanisms.
Feature Summary
- Integrates programmable soft-start and current limiting to manage inrush currents during power insertion
- Provides comprehensive fault protection including overcurrent, overvoltage, and thermal shutdown capabilities
- Features automatic retry functionality to restore power after transient faults clear
Applications
- Industrial backplane systems requiring safe module insertion
- Telecommunications equipment power distribution units
- General-purpose high-reliability power management circuits
Procurement Notes
Verify end-of-life status as the UCC2919PW has been officially discontinued by Texas Instruments. Confirm availability through authorized distributors or secondary market suppliers like Rochester Electronics. Ensure replacement components meet identical electrical specifications and pin compatibility requirements before integration into existing designs.
Selection Notes
Select this component for single-rail hot-swap applications requiring precise control over power-up sequences. Consider the 16-TSSOP package for space-constrained PCB layouts. Evaluate the 3 V to 8 V input range against system bus voltages. Verify that the industrial temperature rating aligns with environmental operating conditions.
Part Context
The UCC2919 belongs to the UCC2919 family of hot-swap controllers designed for robust power management. It serves as a specialized integrated circuit within Texas Instruments' portfolio for protecting sensitive loads during live insertion events. The PW suffix specifically denotes the 16-lead Thin Shrink Small Outline Package variant used in this configuration.
Replacement Considerations
The TPS24700DGK is a confirmed similar replacement part offered by Texas Instruments. Verify functional equivalence regarding control logic and protection thresholds when transitioning from the discontinued UCC2919PW to this alternative component.
