11.1 Layout Guidelines

Directly connecting the MOSFET gate to the output of the driver is straighforward for testing purposes. It does not represent the "real" application which may include several inches of printed circuit board traces. Inductance will sharply degrade the transitions and cause substantial overshoot by ringing with the gate capacitance. This can cause the gate-to-source voltage to overshoot beyond the specified maximum ratings. Additionally, negative transitions (below ground) at the driver output can raise havoc with the internal circuitry, leading to undesirable performance.

Adding Schottky diodes to auxiliary supply rail can help address these concerns.
