The following circuit guidelines should be adhered to for

optimum circuit performance:

1. The VCC bypass capacitor must be placed close to the

VDD and ground pins. It is critical that the etch length

between the decoupling capacitor and the VDD &

GND pins be minimized to reduce pin inductance.

2. A ground plane is recommended to minimize parasitic

inductance and impedance of the return paths. The

MIC44F18 family of drivers is capable of high peak

currents and very fast transition times.

Any

impedance between the driver, the decoupling

capacitors and the external MOSFET will degrade the

performance of the circuit.

3. Trace out the high di/dt and dv/dt paths, as shown in

Figures 7 and 8 and minimize etch length and loop

area

for

these

connections.

Minimizing

these

parameters decreases the parasitic inductance and

the radiated EMI generated by fast rise and fall times.
