TPS2421-1 - FET Hot Swap

General Description

The TPS2421 device provides highly integrated hot swap power management and superior protection in applications where the load is powered by busses up to 20 V.

The TPS2421 device is well suited to standard bus voltages as low as 3.3 V because of the maximum-UV turnon threshold of 2.9 V.

Key Features

  • 1 Integrated Pass MOSFET.
  • Up to 20-V Bus Operation.
  • Programmable Fault Current.
  • Current Limit Proportionally Larger than Fault Current.
  • Programmable Fault Timer.
  • Internal MOSFET Power Limiting.
  • Latch-Off on Fault (TPS2421-1) and Retry (TPS2421-2) Versions.
  • SO-8 PowerPad™ Package.
  • 40°C to +125°C Junction Temperature Range.
  • UL2367 Recognized - File Number E169910 2.
