TPS2491 Datasheet Positive High-voltage Power-limiting Hotswap Controller

Manufacturer: Texas Instruments

Overview: Product Folder Order Now Technical Documents Tools & Software Support & Community TPS2490, TPS2491 SLVS503F – NOVEMBER 2003 – REVISED FEBRUARY 2020 TPS249x Positive High-Voltage Power-Limiting Hot Swap Controller.

This datasheet includes multiple variants, all published together in a single manufacturer document.

General Description

The TPS249x are easy-to-use, positive high voltage, 10-pin Hot Swap Power Manager devices that safely drive an external N-channel MOSFET switch.

The power limit and current limit (both are adjustable and independent of each other) ensure that the external MOSFET operates inside a selected safe operating area (SOA) under the harshest operating conditions.

Applications include inrush current limiting, electronic circuit breaker protection, controlled load turn-on, interfacing to down-stream DC-to-DC converters, and power feed protection.

Key Features

  • 1 Programmable Power Limiting and Current Limiting for Complete Safe Operating Area (SOA) Protection.
  • Wide Operating Range: 9 V to 80 V.
  • Latched Operation (TPS2490) and Automatic Retry (TPS2491).
  • High-Side Drive for Low-RDS(on) External N- channel MOSFET.
  • Programmable Fault Timer to Protect the MOSFET and Eliminate Nuisance Shutdowns.
  • Power Good Open-Drain Output for Downstream DC/DC Coordination.
  • Enable Can Be Used as a Programmable.
