Hot Swap Controllers datasheet and documents for TPS2459RHBR
Hot Swap Controllers Overview
The TPS2459RHBR is a dual-channel hot-swap voltage controller manufactured by Texas Instruments. It operates within an input voltage range of 8.5 V to 15 V and features a VQFN-32 package. The device supports two independent channels with a maximum operating supply current of 4 mA. It functions across a temperature range from -40°C to +85°C and includes humidity sensitivity characteristics.
Hot Swap Controllers Feature Summary
- Provides integrated hot-swap and OR-ing control for dual power paths
- Supports precise voltage monitoring and controlled inrush management
- Includes comprehensive protection against overcurrent and thermal faults
Hot Swap Controllers Applications
- Dual redundant power supply systems
- Hot-swappable server backplanes
- Industrial equipment requiring safe module insertion
Hot Swap Controllers Procurement Notes
Verify the specific suffix RHBR confirms the tape-and-reel packaging format and commercial grade temperature rating. Confirm RoHS compliance status through official documentation before integration. Ensure ESD handling protocols are followed due to moisture sensitivity classification.
Hot Swap Controllers Selection Notes
Select this component when dual-channel hot-swap functionality is required within a 15 V limit. It is suitable for applications needing synchronized power path management. Consider the VQFN-32 footprint constraints during PCB layout planning.
Hot Swap Controllers Part Context
This part belongs to the TPS2459 family of power management ICs designed for robust power distribution. It addresses the need for reliable power sequencing and fault isolation in multi-rail systems without external discrete components.
Hot Swap Controllers Replacement Considerations
Consult official substitution lists for pin-compatible alternatives. Verify electrical parameter alignment for any cross-reference parts.
