Smart diode controller

27 January 2016 Power Electronics / Power Management

Texas Instruments introduced the industry’s first smart diode controller with zero quiescent current that provides better efficiency versus Schottky diodes and p-channel MOSFETs. The LM74610-Q1 provides low power consumption and heat generation in a compact solution size, making it well suited for reverse polarity protection in high-current industrial power tool and automotive applications.

The IC features a unique floating ground architecture that models a diode behaviour with zero ground current. Paired with TI’s CSD17313Q2Q1 NexFET n-channel MOSFET, the duo emulates a diode rectifier when connected in series with a power source, discharging the MOSFET gate in the event of reverse polarity. The LM74610-Q1 can also be used to combine two alternate power sources in an ORing configuration to provide redundancy.

For automotive alternator and industrial power AC rectification, TI offers the LM74670-Q1 smart diode controller, which has higher gate drive current (70 μA) than the LM74610-Q1, allowing it to handle AC signals up to 300 Hz.
