eicedriver? safe 1eds - slew rate control igbt driver ic target datasheet 13 , 05.06.2014 4 functional description 4.1 introduction the 1EDS20I12SV is an advanced igbt gate driver with various control and protection features to allow the design of highly reliable systems. the integrated circuit consis ts of two reinforced isolated s ides, called input side and output side. the input side is typically interfaced with a cmos - compatible standard dsp or a microcontroller. the galvanically isolated output side is connected to the high voltage domain. the adjustable gate current source allo ws the tuning of the igbt turn - on slew rate to limit the emi radiation. the turn - off process is accomplished with an internal mosfet stage capable of driving 2 a. an internal mosfet switch capable of driving 1 a is connected to an external high - impedance g ate resistor and prevents from an overvoltage at the igbt in case of a short or an overcurrent. the driver also includes igbt desaturation protection for conventional igbts and overcurrent protection for sense igbts with the fault status output terminal . t wo ready status output terminal s indicate whether the driver is properly supplied and operates normally. a two - level turn - off feature with adjustable delay protects against excessive overvoltage at turn - off in case of an overcurrent or a short. the same de lay is applied at turn - on to prevent pulse width distortions. figure 3 typical a pplication 4.2 ic supply the start up of the input section and the output section of the 1eds02i12sv needs approx. tbd s for the vcc1 / padp domains and tbd s for the vcc2 domain. however, the ic is in a safe state in any case, meaning that the gate drive outputs are never activated before each part of the ic is ready to operate. the start up times are given in section 5.3.1 . d e s a t r d y 2 r d y 1 r s o f f r o f f v c c 2 t 1 c o n t r o l u n i t 5 v c s / f l t g a t e g n d 2 o n v z v c c 2 o f f r s e n s e c z v e e 2 s o f f o c o f f i n p s p e e d s i g i s i g o v c c 1 i n n p a d p p a d n e n g n d 1 5 v g n d p r b r p r b 1 r p r b 2 r s t 2 r d e s a t d d e s a t c d e s a t r f c f c 3 c 2 v c c 2 r d c d c 1
eicedriver? safe 1eds - slew rate control igbt driver ic target datasheet 14 , 05.06.2014 4.2.1 input side the driver is supplied with 5 v between terminal s vcc1 to gnd1. this supply voltage manages the basic functions of the control side. the control side contains a second voltage domain for the logic input signals inp, inn, and en. this special voltage domain is supplied by the terminals padp and padn and can range from 3.3v over 5v to 15v. it is mandatory to connect directly the terminals padn and gnd1 . i t is important to note, that the voltage domains vcc1 and padp have independent undervoltage lockout levels and both domains must be supplied appropriately for operation. vcc1 can be shorted to gnd1 in order to deactivate the driver. no turn - on signals wil l be transmitted from the input to the output side even if terminal vcc1 is left floating. therefore, the igbt wont be turned on. 4.2.2 output side the eicedriver? 1EDS20I12SV is designed to support both bipolar and unipolar power supply configurations. the dr iver ic is typically supplied with a positive voltage of 15 v on terminal vcc2 and a negative voltage of - 8 v on terminal vee2, if configured for bipolar supply. the driver ic is typically supplied with a positive voltage of 15 v on terminal vcc2 for a uni polar supply configuration. vee2 and gnd2 have to be connected together as short as possible in this case . 4.3 non - inverting and i nverting input terminals inp and inn there are two input modes to control the igbt. in non - inverting mode, terminal inp controls t he driver output while terminal inn is set to low. in inverting mode, terminal inn controls the driver output while terminal inp is set to high. a low signal at terminal inn will activate the output on. a minimum input pulse width is defined to suppress po tential glitches. 4.4 driver o utput terminal on the output stage consists of the internal regulation circuit inside the driver, an external sense resistor r sense , and up to three external p - channel transistors placed in parallel. the recommended p - channel tran sistor is a bsd314spe (optimos? - p 3, 30 v, 140 m?). after a short propagation delay, the igbt is switched on by a regulated current source. the entire turn - on procedure is separated into three phases according to figure 4 : the preboost, the turn - on, and the vcc2 clamping phase. the preboost phase controls a high current to drive the gate of the igbt. this brings the gate voltage from its negative level to a volta ge slightly lower than the gate - emitter threshold voltage if the igbt, i.e. v gate < v ge(th) , within a period of typ. 13 5 ns. the value of the preboost current i prb is proportional to the voltage v prb at terminal prb. the maximum voltage v pr b against vee2 is 5 v. the preboost current i prb is defined as: | | i gg is
eicedriver? safe 1eds - slew rate control igbt driver ic target datasheet 15 , 05.06.2014 figure 4 timing diagram for turn - on finally, the igbt gate voltage saturates at vcc2 in the vcc2 clamping phase. the driver clamps the gate voltage of the external p - channel transistor 6 v below vcc2 according to figure 4 . this provid es a low - ohmic connection between the gate of the igbt and vcc2 it is good board layout engineering to keep tight proximity of the control loop consisting of driver ic, sense resistor, and p - channel mosfet to avoid oscillations. 4.5 preboost setting the preboost timer is always active, both in bipolar or unipolar power supply configuration. the only exception is if the igbt is turned on via en according to section 4.7 t he preboost current may be set by a simple voltage divider for bipolar gate supply as well as for unipolar supply. in case of bipolar power supply, connect the voltage divider between gnd2 , prb, and vee2. in case of a unipolar power supply, use vcc2, prb, and vee2 according to figure 5 . t 3 t 1 t 2 < 1 0 0 n s g a t e r g i n t o n v c c 2 e x t e r n a l t u r n - o n r s e n s e t r a c k i n g t u r n - o n c u r r e n t s o u r c e v c c 2 c l a m p i n g p r e b o o s t v a l u e = f ( v e e 2 , r p r b 1 , r p r b 2 ) v e e 2 v m i l l e r v c c 2 t 0 0 v r s i g g v r s ( t ) 0 . 5 1 6 v ( s t e p 3 ) 1 . 3 3 v a t v e e 2 = 8 v i g g ( t ) v g e ( t ) 1 3 5 n s p r e b o o s t v c c 2 - v o n = 6 v v o n ( t ) p h a s e s : r s v g e t v g e ( t h ) g n d 2 1 e d s - s r c v v o n t
