Overview
The TPS2419PW is a single-channel N+1 OR-ing power rail controller manufactured by Texas Instruments. It operates within an input voltage range of 800 mV to 16.5 V and draws a typical supply current of 1.2 mA. The device is housed in an 8-TSSOP surface-mount package with a maximum power dissipation of 410 mW. It supports operating temperatures from -40°C to +85°C and lacks integrated internal switches or power failure detection capabilities.
Feature Summary
- Supports N+1 redundancy configurations for high-availability power systems
- Enables ideal diode OR-ing functionality using external N-channel FETs
- Features low quiescent current consumption for efficient standby operation
Applications
- N+1 redundant power supply architectures
- High-availability server and storage backplanes
- Telecommunications equipment power distribution
Procurement Notes
Verify the specific suffix against official documentation, as it defines the package type and tape/reel specifications. Confirm RoHS compliance status through the manufacturer's datasheet. Ensure the design accommodates the absence of internal switches by selecting appropriate external MOSFETs. Validate thermal performance within the specified temperature range.
Selection Notes
Select this component when designing redundant power rails requiring precise voltage monitoring without integrated switching. It is suitable for applications needing low standby current and support for multiple parallel power sources. Verify that the external FET selection aligns with the controller's drive capabilities and system voltage requirements.
Part Context
This part belongs to the TPS2419 series of OR-ing controllers. It complements other hot-swap devices like the TPS2410 by focusing on redundancy management rather than individual slot protection. The TSSOP-8 package offers a compact footprint for dense PCB layouts compared to larger SOIC variants.
Replacement Considerations
The UCC2919PW is a discontinued alternative within the same family. For active replacements, consider the TPS24700DGK, which offers similar hot-swap control features in a different package.
