Introduction

AI Translation

The LTC4451 is a high-performance Schottky diode replacement using an integrated N-Channel power MOSFET. It easily ORs power supplies together to increase system reliability and prevent reverse conduction. The LTC4451 regulates the forward voltage at 15mV to minimize power loss compared to Schottky diodes. Regulation ensures smooth current transfer without oscillation in diode-OR applications. When the power MOSFET is fully enhanced, the RDS(ON) of the transistor is 21mΩ and rated for forward conduction up to 7A while dissipating 1.34W. A high performance gate driver with fast transient response minimizes both forward power dissipation and reverse current. The VC input allows VIN to work down to ground for low voltage applications. The LTC4451 is available in a small 16-Lead 2mm × 3mm LQFN Package.
