In addition to its 200V rating, which is twice that of its competitors, the ZXGD3111N7 has a low turn‑off threshold voltage with a tight tolerance of -5 to -1mV. This improves stability under light load conditions when using low RDSON MOSFETs, making this controller a class-leading solution that can deliver the highest efficiency and reliability over the entire load range.
The ZXGD3111N7 is designed to work with a FET to create an ideal diode that replaces the blocking diodes typically used in common rail designs. A 5A sink current capability allows fast discharge of the gates in the parallelled OR’ing MOSFETS and its quick (less than 600ns) turn-off specification avoids reverse current flow and any voltage drop on the common rail. The device has an industry-leading standby power consumption under 50mW with a quiescent supply current of less than 1mA.
The ZXGD3111N7 in an SO-7 package is priced at $1.10 each in 2,500 unit quantities.
