TPS2398DGK

Hot Swap Controllers Overview

The TPS2398DGK is a single-channel hot swap voltage controller designed for -48V systems. It operates within a supply voltage range of -36V to -80V and functions across an industrial temperature range of -40°C to +85°C. Housed in an 8-VSSOP surface-mount package, this device provides intelligent control for high-side N-channel MOSFETs. Key electrical specifications include input under-voltage lockout (UVLO) with hysteresis and programmable input over-voltage protection (OVP). The controller features a latch-off mechanism that persists until the enable input or UVLO input returns to a low state following a detected fault condition exceeding the allowed delay time.

Hot Swap Controllers Feature Summary

• Intelligent control of high-side N-channel MOSFETs for hot swap applications
• Input under-voltage lockout with hysteresis and programmable input over-voltage protection
• Latch-off fault response requiring specific input states to reset

Hot Swap Controllers Applications

• -48V telecommunications infrastructure equipment
• Industrial control systems requiring hot swap capabilities
• Telecom power distribution units

Hot Swap Controllers Procurement Notes

Verify the exact ordering suffix against Texas Instruments documentation to confirm package type and tape/reel specifications. Ensure the component meets RoHS compliance requirements for your assembly process. Confirm the operating temperature range aligns with your system's environmental constraints before finalizing procurement.

Hot Swap Controllers Selection Notes

Select this controller when managing -48V loads with high-side N-channel MOSFETs. It is suitable for applications requiring robust fault protection and remote on/off control via the enable input. Consider the VSSOP-8 package size for space-constrained designs needing single-channel management.

Hot Swap Controllers Part Context

Part of the TPS2398 series from Texas Instruments, focusing on simple yet effective hot swap voltage control. This series addresses the need for reliable power insertion and removal in critical systems without complex external circuitry.

Hot Swap Controllers Replacement Considerations

Consult official substitution guides for compatible alternatives within the hot swap controller category. Verify pin compatibility and electrical parameters before replacing.
