Hot Swap Controllers datasheet and documents for TPS2398DGKR
Hot Swap Controllers Overview
The TPS2398DGKR is a hot-swap voltage controller designed for -48V systems. It provides single-channel protection with an external N-channel MOSFET. Key electrical parameters include a supply voltage range of -80V to -36V and an operating temperature range from -40°C to +85°C. The device features programmable current limiting, fault timeout, and slew rate control. It is housed in an 8-VSSOP package.
Hot Swap Controllers Feature Summary
- Integrates programmable current limit, fault timeout, and slew rate control for precise power-up sequencing.
- Supports -48V hot-swap applications with external N-channel MOSFET switching.
- Includes undervoltage lockout (UVLO) and latch-off fault protection mechanisms.
Hot Swap Controllers Applications
- -48V telecommunications infrastructure
- Industrial control systems
- Telecom backplane power distribution
Hot Swap Controllers Procurement Notes
Verify the specific ordering suffix 'DGKR' corresponds to the tape-and-reel packaging configuration. Confirm that the component matches the Texas Instruments datasheet specifications for the TPS2398 series. Ensure compatibility with -48V system requirements and VSSOP-8 footprint dimensions before procurement.
Hot Swap Controllers Selection Notes
Select this controller when designing -48V hot-swap circuits requiring external MOSFET management. It is suitable for applications needing programmable soft-start and fault handling. Consider the VSSOP-8 package size and thermal performance relative to the external switch selection.
Hot Swap Controllers Part Context
The TPS2398 belongs to the Texas Instruments hot-swap voltage controller family. These devices manage power insertion into live backplanes without causing voltage droops or damage. The DGKR variant specifically denotes the reel-packaged version of the standard TPS2398DGK.
Hot Swap Controllers Replacement Considerations
Consult official documentation for direct substitutes within the TPS239x series. Verify pinout compatibility and electrical ratings before replacing with other hot-swap controllers.
