Layout and Connection Guidelines
The FAN3100 incorporates fast-reacting input circuits,
short propagation delays, and pow erful output stages
capable of delivering current peaks over 2 A to facilitate
voltage transition times from under 10 ns to over 100 ns.
The follow ing layout and connection guidelines are
strongly recommended:
Keep high-current output and pow er ground paths
separate from logic input signals and signal ground
paths. This is especially critical w hen dealing w ith
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
sw itching, w hile reducing the loop area that can
radiate EMI to the driver inputs and other surrounding
circuitry.
The FAN3100 is available in tw o packages w ith
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 pow er ground, Pin 5, through
a short direct path underneath the IC. In the 5-pin
SOT23, the internal analog and pow er ground
connections are made through separate, individual
bond w ires to Pin 2, w hich should be used as the
common ground point for pow er and control signals.
Many high-speed pow er circuits can be susceptible
to noise injected from their ow n 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 w ith 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 follow ing sections.
Figure 43 show s the pulsed gate drive current path w hen
the gate driver is supplying gate charge to turn the
MOSFET on. The current is supplied from the local bypass
capacitor, CBYP, and flow s 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 CBYP acts to
contain the high peak current pulses w ithin this driver-
MOSFET circuit, preventing them from disturbing the
sensitive analog circuitry in the PWM controller.

Figure 43. Current Path for MOSFET Turn-On
Figure 44 show s the current path w hen the gate driver
turns the MOSFET off. Ideally, the driver shunts the
current directly to the source of the MOSFET in a small
circuit loop. For fast turn-off times, the resistance and
inductance in this path should be minimized.

Truth Table of Logic Operation
The truth table indicates the operational states using the
dual-input
configuration.
In
a
non-inverting
driver
configuration, the IN- pin should be a logic LOW signal. If
the IN- pin is connected to logic HIGH, a disable function is
realized, and the driver output remains LOW regardless of
the state of the IN+ pin.

In the non-inverting driver configuration in Figure 45, the
IN- pin is tied to ground and the input signal (PWM) is
applied to IN+ pin. The IN- pin can be connected to logic
HIGH to disable the driver and the output remains LOW,
regardless of the state of the IN+ pin.

In the inverting driver application show n in Figure 46, the
IN+ pin is tied HIGH. Pulling the IN+ pin to GND forces the
output LOW, regardless of the state of the IN- pin.
