Layout and Connection Guidelines
The FAN3100 incorporates fast reacting input circuits,
short propagation delays, and powerful output stages
capable of delivering current peaks over 2A to facilitate
voltage transition times from under 10ns to over 100ns.
The following layout and connection guidelines are
strongly recommended:

Keep high-current output and power ground paths
separate from logic input signals and signal ground
paths. This is especially critical when dealing with
TTL-level logic thresholds.
Keep the driver as close to the load as possible to
minimize the length of high-current traces. This
reduces the series inductance to improve high-
speed switching, while reducing the loop area that
can radiate EMI to the driver inputs and other
surrounding circuitry.
The FAN3100 is available in two packages with
slightly different pinouts, offering similar
performance. In the 6-pin MLP package, Pin 2 is
internally connected to the input analog ground and
should be connected to power ground, Pin 5,
through a short direct path underneath the IC. In the
5-pin SOT23, the internal analog and power ground
connections are made through separate, individual
bond wires to Pin 2, which should be used as the
common ground point for power and control signals.
Many high-speed power circuits can be susceptible
to noise injected from their own output or other
external sources, possibly causing output re-
triggering. These effects can be especially obvious
if the circuit is tested in breadboard or non-optimal
circuit layouts with long input, enable, or output
leads. For best results, make connections to all pins
as short and direct as possible.
The turn-on and turn-off current paths should be
minimized as discussed in the following sections.
Figure 43 shows the pulsed gate drive current path
when the gate driver is supplying gate charge to turn the
MOSFET on. The current is supplied from the local
bypass capacitor, C BYP , and flows through the driver to
the MOSFET gate and to ground. To reach the high
peak currents possible, the resistance and inductance in
the path should be minimized. The localized C BYP acts to
contain the high peak current pulses within this driver-
MOSFET circuit, preventing them from disturbing the
sensitive analog circuitry in the PWM controller.
