none of the inputs to u1 or u2 of the drf1300 are isolated for direct connection to a ground referenced power supply or control circuitry. isolation appropriate to the application is the responsibility of the end user. it is imperative that high output currents be restricted to the source (14, 16, 18) and drain (15, 17) pins by design. see drf100 for more information on driver ic used in the device. the function (fn, pin 3 or pin 9) is the invert or non-invert select pin, it is internally held high. microsemi?s products are covered by one or more of u.s. patents 4,895,810 5,045,903 5,089,434 5,182,234 5,019,522 5,262,336 6,5 03,786 5,256,583 4,748,103 5,283,202 5,231,474 5,434,095 5,528,058 6,939,743 and foreign patents. us and foreign patents pending. all rights res erved. DRF1301 050-4975 rev b 4-2009 the test circuit illustrated in figure 2 was used to evaluate the DRF1301 (available as an evaluation board drf13xx/evalsw.) t he input control signal is applied via in and sg pins using rg188. this provides excellent noise immunity and control of the signal gro und currents. the +v dd inputs (pins 2, 6, 8 and 12) should be heavily by-passed by 1uf capacitors as close to the pins as possible. the capacitors u sed for this function must be capable of supporting the rms currents and frequency of the gate load. a 50 ohm (rl) load is used to evaluate the output performance. figure 2, DRF1301 test circuit truth table * referenced to sg fn (pin 3) in (pin 4) mosfet u1 high high on high low off low high off low low on truth table * referenced to sg fn (pin 9) in (pin 10) mosfet u2 high high on high low off low high off low low on
