LM74721EVM Controller Evaluation Module

Texas Instruments LM74721EVM Controller Evaluation Module (EVM) helps designers evaluate the operation and performance of the LM74721-Q1 ideal diode controller in reverse battery protection applications. This evaluation module demonstrates how LM74721-Q1 controls two N-channel power MOSFETs with an ideal diode MOSFET connected first, followed by a second MOSFET for switched output and power path cut off. The Texas Instruments LM74721-Q1 can withstand and protect the loads from negative supply voltages down to –33V DC. An integrated ideal diode controller (GATE) drives the first MOSFET to replace a Schottky diode for reverse input protection and output voltage holdup. Integrated VDS clamp feature enables input TVS fewer system designs for automotive ISO7637 pulse suppression. A strong boost regulator with fast turn ON/OFF comparators ensures robust and efficient MOSFET switching performance during automotive testing, such as ISO16750 or LV124, where an ECU is subjected to input short interruptions, and AC superimpose input signals.
