Overview
The TPS2490DGSRG4 is a latchable positive high-voltage power-limiting hot swap controller manufactured by Texas Instruments. It operates within a supply voltage range of 9 V to 80 V and supports a single channel. The device features programmable current limiting, fault timeout, and under-voltage lockout (UVLO). It is housed in a 10-VSSOP package with a maximum operating temperature of +85°C and a minimum of -40°C. The quiescent supply current is 1 mA, and the power dissipation is rated at 376 mW.
Feature Summary
- Provides latchable fault protection for high-voltage hot swap applications
- Integrates programmable current limiting and power limiting capabilities
- Includes built-in fault timeout and under-voltage lockout mechanisms
Applications
- High-voltage server backplanes
- Industrial control systems requiring hot insertion
- Telecommunications infrastructure equipment
Procurement Notes
Verify the specific suffix 'RG4' indicates RoHS compliance and green material status as per Texas Instruments documentation. Confirm the package type is 10-VSSOP (DGS) and ensure the ordering part number matches the required tape-and-reel configuration versus tube packaging. Cross-reference the datasheet revision date to ensure compatibility with latest design guidelines.
Selection Notes
Select this component when a latchable shutdown response is required following a fault condition, distinguishing it from auto-retry variants like the TPS2491. Ensure the input voltage range of 9 V to 80 V aligns with the system bus. Consider the 10-VSSOP package constraints for thermal management, given the 376 mW power dissipation rating and surface-mount installation requirement.
Part Context
This part belongs to the TPS2490 series of hot swap controllers from Texas Instruments. It is functionally similar to the TPS2490DGS but may differ in packaging format or compliance markings. The DGSR variant typically denotes tape-and-reel packaging, while DGS refers to the tube version. Both share the same core electrical specifications and pinout.
Replacement Considerations
The TPS2490DGS is a direct functional substitute with identical electrical characteristics, differing primarily in packaging quantity and form factor. The TPS2491DGSR offers similar voltage and current limits but utilizes an auto-retry mechanism instead of latch-off behavior.
