28 V, 5 A dual channel non-isolation gate driver

NGD31251 is a high-frequency, dual channel, non-isolation MOSFET gate driver for high power automotive application.

NGD31251 has typical 5 A sink and 5 A source drive current and it can handle -10 V on its input pins, which improves robustness in systems with moderate ground bouncing. The inputs are independent of supply voltage and can be connected to most controller outputs.

NGD31251 has 11 ns rising and 13 ns falling propagation delay which allows the systems operating at high frequency with less delay matching variations. These delays are very suited for applications requiring dual-gate drivers with critical timing, such as synchronous rectifiers. When connecting two channels in parallel to increase current-drive capability, delay matching between 2 channels (2 ns) is used to avoid shoot through current without adding external series resistor.

Interactive datasheet

How does it work?

The interactive datasheets are based on the Nexperia MOSFET precision electrothermal models. With our interactive datasheets you can simply specify your own conditions interactively. Start by changing the values of the conditions. You can do this by using the sliders in the condition fields. By dragging the sliders you will see how the MOSFET will perform at the new conditions set.
