Overview

The TPS2421-2EVM-03 is a 3-V to 18-V module using the TPS2421-2 hot swap controller with integrated MOSFET. At power on, the output is power limited to control inrush current and protect the MOSFET. On an over-current condition, the controller interrupts power to the load at high speed and signals load status. Operating current, fault current and fault timer settings are hardware programmable.

Features
  • 3V to 18V Operation
  • Controlled Inrush Current
  • Fast Circuit Breaker Control
  • Hardware Programmable
  • LED status display
  • A Slide Switch Controls the ENABLE Signal
  • The Area Under the TPS2421-2 is Copper Pour with Vias to the Internal Ground to take Advantage of the Power Pad Package
  • A Transorb is On-Board for Over-Voltage Input Protection
  • A Common Diode at the Output Prevents a Negative Spike if the Load is Removed While Powered On
  • Programmable IMON Voltage Readout of the Output Current is Preset to 0.31 V / A
  • Test Points Available to Monitor Circuit Operation
