Hot Swap Controllers datasheet and documents for TPS2458RHBR

TPS2458RHBR

Hot Swap Controllers Overview

The TPS2458RHBR is a dual-channel hot-swap voltage controller manufactured by Texas Instruments. It supports input voltages from 8.5 V to 15 V and operates within a temperature range of -40°C to +85°C. The device features two independent channels, each capable of managing power sequencing and protection for high-side loads. Packaged in a 32-pin VQFN (RHBR) surface-mount case, it draws a typical operating supply current of 4 mA. This component is designed for robust power management applications requiring precise control over voltage ramp-up and fault conditions.

Hot Swap Controllers Feature Summary

Dual-channel architecture for independent load management
Integrated hot-swap control with soft-start capabilities
Comprehensive protection against overcurrent and thermal faults

Hot Swap Controllers Applications

High-side load switching in industrial systems
Power distribution units (PDUs)
Telecommunications equipment power modules

Hot Swap Controllers Procurement Notes

Verify the specific package marking and date code upon receipt to ensure authenticity. Confirm that the received components match the TPS2458RHBR designation exactly. Check for moisture sensitivity indicators as the device is humidity-sensitive. Ensure storage conditions comply with manufacturer guidelines prior to assembly to prevent internal damage during soldering processes.

Hot Swap Controllers Selection Notes

Select this component when dual-channel hot-swap functionality is required within an 8.5 V to 15 V input range. It is suitable for designs needing integrated protection without external discrete logic. Consider the VQFN-32 package for space-constrained PCB layouts. Evaluate thermal performance requirements against the specified operating temperature range before implementation.

Hot Swap Controllers Part Context

This part belongs to the TPS245x series of hot-swap controllers from Texas Instruments. It complements other devices like the TPS2459 by offering dual-channel control rather than single or mixed configurations. The RHBR suffix indicates the specific tape-and-reel packaging format compatible with automated surface-mount assembly lines.
