Hot Swap Controllers datasheet and documents for TPS2458RHBT
Hot Swap Controllers Overview
The TPS2458RHBT is a dual-channel hot swap and ORing controller designed for AdvancedMC applications. It operates with input voltages ranging from 3 V to 15 V, supporting both 12-V and 3.3-V systems. The device integrates two internal switches and provides load current monitoring. It features a VQFN-32 package (5x5 mm) suitable for surface-mount installation. Operating temperatures range from -40°C to +85°C.
Hot Swap Controllers Feature Summary
- Integrates dual internal switches for independent channel control
- Provides precise load current monitoring capabilities
- Supports programmable fault timeout and slew rate settings
Hot Swap Controllers Applications
- AdvancedMC (Advanced Mezzanine Card) systems
- MicroTCA carrier architectures
- Dual power supply redundancy configurations
Hot Swap Controllers Procurement Notes
Verify the specific suffix RHBT confirms the VQFN-32 package variant. Confirm RoHS compliance status through official documentation. Ensure the operating voltage range matches the target system requirements of 3 V to 15 V. Validate thermal performance specifications against the intended ambient temperature conditions.
Hot Swap Controllers Selection Notes
Select this component when dual-channel hot swap protection and current monitoring are required in compact form factors. It is suitable for designs needing integrated ORing functionality without external diodes. Consider the VQFN-32 footprint constraints during PCB layout. Verify compatibility with AdvancedMC standards if used in mezzanine card designs.
Hot Swap Controllers Part Context
This part belongs to the TPS2458 family of hot swap controllers. It shares functional similarities with the TPS2459 but offers distinct pinout and feature sets tailored for specific board layouts. The RHBT suffix denotes the tape and reel packaging format within the VQFN-32 enclosure.
Hot Swap Controllers Replacement Considerations
The TPS2458RHBR is a compatible alternative offering identical electrical characteristics in a different packaging configuration. Verify pin-to-pin compatibility before substitution. Ensure the replacement package meets the mechanical constraints of the existing design.
