15 / 17 page  Micrel, Inc. MIC44F18/19/20 February 2011 15 M9999-020111 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. |
