LM74800-Q1 ideal diode controller evaluation module


Order now


TI's Evaluation Module LM74800EVM-CD helps designers evaluate the operation and performance of the LM7480-Q1 ideal diode controllers (LM74800QDRR and LM74801QDRR) in reverse battery protection applications. This evaluation module demonstrates how LM7480-Q1 controls two back-back N-channel power MOSFETs with ideal diode MOSFET connected first followed by second MOSFET for switched output and power path cut-off.

  • Reverse battery protection
  • Switched output and power path cut-off
  • Over voltage protection
  • Meets automotive transient immunity test requirements
  • Two external N-Channel MOSFETs connected back-back in common drain configuration
Ideal diode/ORing controllers
LM7480-Q1 3-V to 65-V, automotive ideal diode controller driving back to back NFETs
