eval - adum4135ebz user guide ug- 854 rev. 0 | page 3 of 6 setting up the eval - adum4135ebz initial configuratio n before the first use, c ertain things must be compl eted to prepare the board for operation. in the stock configuration, the r1 to r6 resistors are not placed. these are the locations of the series external resistors for the charging and discharging paths to v out_on and v out_off . it is recommended to use 12 06 surface - mount resistors with values between approximately 1 and 10 , depending on the load being driven. an actual igbt or mosfet can be placed in the provided landing patterns to the right of p1 and p2. p1 and p2 allow shorting across the series external resis tors to observe overshoot and/or allow the user to probe voltage to quantify peak currents. in the stock configuration, the d esat circuitry is left open. before the first use, if desat functionality is not used, it is recommended to short the desat pin to ground, either by a wire or by placing a 0 resistor in the c6 component pad. failure to do so result s in a desat fault being observed on the first rising edge of the output. if the desat circuitry is tested, an igbt or mosfet must be added to the circuit to allow for the desat pin to be pulled down during on times, preventing the desat fault. additionally, c6, r12, and d1 must have appropriate components placed . for details about sizing, refer to the adum4135 data sheet . r11 is provi ded to allow extra desat blanking current by means of an external pull - up resistor. c7 can provide decoupling for this external pull - up current source , if desired. r13 and r14 come with 10 k resistors in place. these resistors provide pull ups to the ready and nfault pins. p3 allows for easy enabling and disabling of the device by means of jumper pins. a silkscreen reminder is included to show which pins to short to enable or disable the device. r8 and r10 allow for easy placement of 50 terminating resistors , if desired. pins accompany t he screw terminals. it is left to the user to decide which connection mechanism to use. do not leave v ss2 floating. it must always be at or less than the potential of gnd 2 . shorting vss2 and gnd2 is a valid operating point. during operation, if a fault is seen, the nfault pin is brought low. in this case, the device can be reset by either powering down vdd 1 to vss 1 and powering back up, or by bringing the nreset pin low then high again. the easiest way to toggle nreset is to remove the jump er o n p3 from p in 2 and pin 3 and then replace it . an internal pull - down resistor bring s nreset low on its own. pad layout for the device unde r test ( dut ) figure 4 shows the top layer artwork for the dual gate driver circuit . ? u1 is the footprint for th e adum4135 . ? c1, c2 , and c4 are 0.1 f bypass capacitors; c3 and c5 are 10 f bypass capacitors. ? the available footprint can be populated with to - 252 mosfets or igbts with the pinout shown in figure 2 . ? r1 to r6 are gate resistors that c ontrol the edge s of the output s. by default, no resistors are installed ; these resistors must be populated with low value 1206 resistors , generally in the 1 to 10 range . 2 c/ d 1 g 3 e/ s 13301-002 figure 2 . igbt/mosfet footprint power connections f ollo w these steps t o connect the e va l - adum4135ebz evaluation board to the power supply: 1. connect the 5 v or 3.3 v input supply with the pos itive te rminal on vdd1 and the ground on v ss1 . 2. connect the adum4135 vdd2 supply voltage ( 12 v to 30 v) to t he v dd2 pin and its return to the v ss2 pin . vss1 and vss2 are functionally isolated. the emitter/source of the igbt/mosfet is tied to gnd2 . input/output connection s the v i + and v i? pins are cmos inputs. r8 and r10 are provided in case the user needs to terminate the inputs with a 50 load. r7 and r9 are provided as a place to put damping , if needed ; however, in m ost cas es , the 0 resistors that come s in the stock configuration can remain on r7 and r9. the e va l - adum4135ebz evaluation board comes with screw terminals for both the input and output connections. these are to facilitate connection options but are not the best option for high performance transient testing. the best measurements performed on the load, whether it is an igbt or mosfet or a load capacitor , come from small loop m easurements performed right at the load. using the screw terminals as either the sensing node or for the connection of the load often result s in overshoot being observed during measurement.
