Re: Is it allowed to drive MOSFET current in same dirn as di
As a popular example, reverse drain current mode is the standard operation in the low-side switch of a synchronous buck converter.
Also H-briges are utilizing both drain current polarities. Reverse operation is usually not represented in the datasheet with explicite
characteristics. Because Vds is restricted to values below a diode forward voltage, you're effectively unable to see deviations from
linear Rdson behaviour. In other words, you can roughly apply the Rdson(Vgs) characteristic for inverse drain current as well.
