Texas Instruments LM74610-SQEVM Evaluation Module (EVM)

Texas Instruments LM74610-SQEVM Evaluation Module (EVM) demonstrates reverse polarity protection as a replacement of Schottky Diodes and P-Channel MOSFETs. In this reverse polarity protection solution, the LM74610 Smart Diode Controller is used to provide a gate drive for 40V (VDS) external N-Channel MOSFET. The LM74610-SQEVM emulates an ideal diode property when connected in series with a power supply. When a negative voltage is sensed at the input, the LM74610 pulls down the MOSFET gate and isolates the connected load from the power supply. The TVS voltage clamping diodes D1_1 and D1_2 make LM74610-SQEVM safe for ISO7637 transient pulse testing.

Features

  • 40V Maximum input voltage is the drain-source voltage of the MOSFET
  • Fast response to dynamic current reversal <10μs
  • 75A Maximum load current is drain current (Id)
  • Zero Iq and low reverse leakage current
  • Meets automotive ISO7637 and CISPR25 requirements
