LM74912-Q1 Ideal Diode Controller

Texas Instrument LM74912-Q1 Ideal Diode Controller drives and controls external back-to-back N-channel MOSFETs. This feature is done to emulate an ideal diode rectifier with power path ON/OFF control with overvoltage, undervoltage, and output short-circuit protection. The wide input supply of 3V to 65V allows protection and control of 12V and 24V automotive battery-powered ECUs. The device can protect and withstand the loads from negative supply voltages down to -65V. An integrated ideal diode controller (DGATE) drives the first MOSFET to replace a Schottky diode for reverse input protection and output voltage holdup. With a second MOSFET in the power path, the device allows load disconnect (ON/OFF control) in case of overcurrent and overvoltage events using HGATE control. The device has an integrated current sense amplifier, which provides external MOSFET VDS sense-based short circuit protection with an adjustable current limit. When a short circuit condition is detected on the output, the device latches off the load disconnect MOSFET. The device features an adjustable overvoltage cut-off protection feature. The device features a SLEEP mode, which enables ultra-low quiescent current consumption (6µA) and, at the same time, provides a refresh current to the always ON loads when the vehicle is in the parking state. The Texas Instruments LM74912-Q1 has a maximum voltage rating of 65V.
