Overview
The TPS2412PWRG4 is a single-channel hot-swap voltage controller designed for N+1 redundancy and OR-ing power rail applications. It operates within an input voltage range of 800 mV to 16.5 V, with a quiescent current of 1.2 mA. The device supports programmable current limiting and features an 8-pin TSSOP package. It functions reliably across an extended temperature range from -40°C to +85°C.
Feature Summary
- Supports N+1 redundancy and OR-ing configurations for power rail control
- Features programmable current limiting for precise load management
- Enables safe insertion and removal of live boards via controlled ramp-up
Applications
- Server and storage backplane power distribution
- Telecommunications infrastructure power systems
- Industrial equipment hot-swappable modules
Procurement Notes
Verify the specific suffix 'G4' indicates lead-free compliance and RoHS status as per Texas Instruments documentation. Confirm the TSSOP-8 package marking and pinout alignment with design schematics. Ensure the ordering part number matches the exact thermal and electrical specifications required for the target application environment.
Selection Notes
Select this component when designing systems requiring single-channel hot-swap protection with programmable current limits. It is suitable for low-voltage high-current applications operating between 800 mV and 16.5 V. Consider the TSSOP-8 footprint and -40°C to +85°C operating range during PCB layout and thermal planning.
Part Context
This part belongs to the TPS241x family of hot-swap controllers from Texas Instruments. It provides essential protection against overcurrent and inrush currents during board insertion. The device integrates gate drive capabilities to control external N-channel MOSFETs, ensuring smooth power ramp-up and reliable fault handling in redundant power architectures.
Replacement Considerations
The TPS2412D serves as a direct alternative in an SOIC-8 package. Verify package dimensions and pin compatibility before substitution. Other family members like TPS2410 or TPS2413 offer different channel counts or feature sets.
