? 2012 fairchild semiconductor corporation www.fairchildsemi.com fan3216 / fan3217 ? rev. 1.0.0 12 layout and connection guidelines the fan3216 and fan3217 gate drivers incorporate 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 150ns. 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 for ttl-level logic thresholds at driver input pins. ? keep the driver as close to the load as possible to minimize the length of hi gh-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 surrounding circuitry. ? if the inputs to a channel are not externally connected, the internal 100k ? resistors indicated on block diagrams command a low output. in noisy environments, it may be necessary to tie inputs of an unused channel to vdd or gnd using short traces to prevent noise from causing spurious output switching. ? 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 obvious if the circuit is tested in breadb oard or non-optimal circuit layouts with long input or output leads. for best results, make connections to all pins as short and direct as possible. ? fan3216 and fan3217 are pin-compatible with many other industry-standard drivers. ? the turn-on and turn-off current paths should be minimized, as discussed in the following section. figure 30 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. figure 30. current path for mosfet turn-on figure 31 shows the current path when 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. figure 31. current path for mosfet turn-off
