It is designed to drive an – Exceeds HBM ESD Classification Level 2 external MOSFET to emulate an ideal diode rectifier when connected in series with a power source. A – Device CDM ESD Classification Level C4B unique advantage of this scheme is that it is not • Maximum reverse voltage of 45 V referenced to ground and thus has Zero Iq. • No Positive Voltage limitation to Anode terminal The LM74610-Q1 controller provides a gate drive for • Charge Pump Gate Driver for external N-Channel an external N-Channel MOSFET and a fast response MOSFET internal comparator to discharge the MOSFET Gate • Lower Power Dissipation than Schottky in the event of reverse polarity. This fast pull-down Diode/PFET solutions feature limits the amount and duration of reverse current flow if opposite polarity is sensed. The device • Low reverse leakage current design also meets CISPR25 Class 5 EMI • Zero IQ specifications and automotive ISO7637 transient • Fast 2µs Response to Reverse Polarity requirements with a suitable TVS diode. • -40°C to 125°C Operating Ambient Temperature Device Information(1) • Can be used in OR-ing Applications PART NUMBER PACKAGE BODY SIZE (NOM) • Meets CISPR25 EMI Specification LM74610-Q1 VSSOP (8) 3.0 mm x 5.0 mm • Meets Automotive ISO7637 Transient (1) For all available packages, see the orderable addendum at Requirements with a suitable TVS Diode the end of the datasheet. 2 Applications • ADAS • Infotainment Systems • Power Tools (Industrial) • Transmission Control Unit (TCU) • Battery OR-ing Applications Smart Diode Configuration 1 An IMPORTANT NOTICE at the end of this data sheet addresses availability, warranty, changes, use in safety-critical applications, intellectual property matters and other important disclaimers.
