Texas Instruments TPS25984EVM Evaluation Module

Texas Instruments TPS25984EVM Evaluation Module allows reference circuit evaluation of TPS25984 eFuse. This TPS25984 device is a 70A (peak) stackable eFuse with an accurate and fast current monitoring feature, designed to operate at a 4.5V to 16V input voltage range. The TPS25984EVM evaluation module comes with two TPS25984 eFuses connected in parallel to evaluate a 12V (typical) and 110A (steady-state) design. This evaluation board features a 14A to 120A programmable circuit breaker, an adjustable output voltage slew-rate control, and an adjustable transient current blanking timer. This board also features an adjustable current limit during start-up and an active current sharing threshold using onboard jumpers. The TPS25984EVM evaluation module is used in input hot-swap/hot-plug, server and high-performance computing, network interface cards, graphics and hardware accelerator cards, data center switches, and routers.

Features

  • 5V to 16V (typical) operating voltage range
  • 14A to 120A programmable circuit breaker threshold using onboard jumpers
  • Adjustable reference voltage for overcurrent protection and active current-sharing blocks
  • Adjustable current limit during start-up and active current sharing threshold using onboard jumpers
  • Adjustable output voltage slew rate control
  • Adjustable transient current blanking timer
  • TVS diode for input and Schottky diode for output transient protections
  • LED status for power good and fault indications
  • Options to engage the power cycle and the Quick Output Discharge (QOD)
  • Option to apply custom load transients using onboard MOSFETs, gate drive circuit, and load resistors

Applications

  • Input hotswap and hotplug
  • Server and high-performance computing
  • Network interface cards
  • Fan trays
  • Graphics and hardware accelerator cards
  • Datacenter switches and routers

TPS25984EVM Setup with Test Equipment

Texas Instruments TPS25984EVM Evaluation Module

Follow these instructions before starting any test and repeat again before moving to the next test:

• Set the power supply output (VIN) to zero volts
• Turn off the power supply
• Adjust the jumper positions on EVM to the default configuration as shown in the table
• Turn the power supply on and set the power supply output (VIN) to 12V, 200A, and keep the power supply output disabled
• Enable the power supply output so that the EVM gets the input power supply
