Overview
The TPS2411RMST is a hot-swap voltage controller manufactured by Texas Instruments, designed for N+1 or OR-ing power rail control applications. It operates within an input voltage range of 800 mV to 16.5 V and features a programmable current limit. The device supports single-channel operation with a typical operating supply current of 1.2 mA. It includes power failure detection capabilities and functions across a temperature range of -40°C to +85°C. The component is housed in a TSSOP-14 surface-mount package.
Feature Summary
- Supports N+1 redundancy and OR-ing configurations for power rail management
- Features programmable current limiting for precise load protection
- Includes integrated power failure detection functionality
Applications
- Server and storage system power distribution
- Industrial equipment power supply modules
- Telecommunications infrastructure power systems
Procurement Notes
Verify the specific suffix RMST against official Texas Instruments documentation to confirm tape-and-reel packaging and exact pinout configuration. Ensure compatibility with required thermal dissipation standards for the intended application environment. Cross-reference RoHS compliance status using the manufacturer's latest product data sheet before finalizing procurement orders.
Selection Notes
Select this component when designing systems requiring redundant power architectures or hot-swappable power rails. Consider the 16.5 V maximum input rating and programmable current limits to match source capabilities. Evaluate the TSSOP-14 package size constraints and ensure adequate PCB layout space for thermal management during continuous operation under load conditions.
Part Context
This part belongs to the TPS241x family of hot-swap controllers from Texas Instruments. It shares functional similarities with variants like the TPS2411PW but differs in packaging and reel specifications. The series is engineered for robust power management in critical infrastructure, providing reliable fault protection and seamless power path control for high-availability designs.
Replacement Considerations
Public confirmed substitute part numbers include TPS2411PWG4, TPS2411PWR, and TPS2411PW. Verify that alternative packages maintain identical pin assignments and electrical characteristics to ensure direct interchangeability without circuit redesign.
