MAX16173ATB/VY+

MAX16173 is an ideal diode controller with active rectifier that provides system protection against input transients and reversecurrent conditions. The wide operating voltage range of 3V to 50V, combined with 3μA of shutdown current, this makes ideal for automotive applications. It features an integrated boost converter that is capable of driving the gate of the external n-channel power MOSFET 11V above the source during high load operation. Fast pull up and pull down current sources allow rectification of 50KHz to 250KHz AC components riding on the main supply input. In light load applications, the MAX16173 regulates the voltage between the source and drain of the external n-channel MOSFET to 20mV(typ). For high load applications, the gate is driven high to enhance operation mode to minimize power dissipation and to increase system's power efficiency. Application includes automotive power systems, network telecom power systems, RAID systems servers.
