Texas Instruments LM74502EVM Controller Evaluation Module (EVM)

Texas Instruments LM74502EVM Controller Evaluation Module (EVM) is for evaluating the performance of the ideal diode controller with switched output with the LM74502 and LM74502H. The Texas Instruments LM74502 ideal diode controllers drive and control external back-to-back N-channel MOSFETs to emulate an ideal diode rectifier with power path ON and OFF control and overvoltage protection.

Features

  • Input operating range 3V to 40V, extendable to 65V
  • 24V industrial reverse polarity protection
  • Output voltage slew rate control
  • 5A maximum load current with an option for 10A operation
  • LED Indication for output ON and OFF detection

Required Equipment

  • Power Supplies
    • One adjustable power supply 0V to 40V output, 0A to 10A output current limit
  • Oscilloscope
    • A DPO2024 or equivalent, three 10x voltage probes, and a DC current probe capable of measuring 10A
  • Meters
    • One digital multi-meter minimum needed
  • Loads
    • One resistive load or equivalent which can tolerate up to 10A DC load at 12V

Applications

  • PLC digital output module
  • Industrial reverse polarity protection (24V)
  • Transient suppressor, surge stopper
  • Motor drives safety control card input protection
