Overview
The TPS2412PWR is a hot-swap voltage controller designed for N+1 or-ORing power rail control applications. It supports input voltages from 800 mV to 16.5 V and operates within a temperature range of -40°C to +85°C. The device features programmable current limiting and draws 1.2 mA of operating supply current. It is housed in an 8-pin TSSOP package suitable for surface-mount installation.
Feature Summary
- Supports N+1 redundancy and OR-ing configurations for high-availability power systems
- Features programmable current limiting for flexible load protection
- Designed for efficient hot-swap operations with low quiescent current consumption
Applications
- N+1 redundant power supply architectures
- High-availability server and communication equipment power rails
- Load sharing among multiple power sources
Procurement Notes
Verify the specific suffix PWR corresponds to the TSSOP-8 package and reel/cut-tape packaging options when sourcing. Confirm RoHS compliance status and ensure the supplier provides official Texas Instruments documentation to validate authenticity and manufacturing origin before purchase.
Selection Notes
Select this component for designs requiring precise control over hot-swap events and current limiting in multi-source power systems. Ensure the input voltage range aligns with the system bus requirements and that the thermal performance of the TSSOP-8 package meets the application's heat dissipation needs under maximum load conditions.
Part Context
This part belongs to the TPS241x family of hot-swap controllers from Texas Instruments, which are optimized for protecting power buses during insertion and removal. The TPS2412 variant specifically targets applications needing programmable current limits without integrated power FETs, allowing designers to select external MOSFETs based on specific voltage and current ratings.
Replacement Considerations
The TPS2413PWR is a related part within the same family offering similar functionality but may differ in specific electrical characteristics or pinout compatibility. Verify datasheet specifications for both parts to ensure interchangeability regarding current limit programming and control logic.
