The LM74810-Q1 ideal diode controller drives and controls external back to back N-ChannelMOSFETs to emulate an ideal diode rectifier with power path ON/OFF control and over voltageprotection. The wide input supply of 3V to 65V allows protection and control of 12-V and 24-Vautomotive battery powered ECUs. The device can withstand and protect the loads from negativesupply voltages down to –65 V. An integrated ideal diode controller (DGATE) drives the first MOSFETto replace a Schottky diode for reverse input protection and output voltage holdup. A strong chargepump of 3mA with 50mA peak GATE source current driver stage and short turn ON and turn OFF delaytimes ensures fast transient response ensuring robust and efficient MOSFET switching performanceduring automotive testing such as ISO16750 or LV124 where an ECU is subjected to input shortinterruptions and AC superimpose input signals upto 200KHz frequency. With a second MOSFET in thepower path the device allows load disconnect (ON/OFF control) and over voltage protection usingHGATE control. The device features an adjustable over voltage cut-off protection feature for loaddump protection.
