www.eupec.com - www.eicedriver.com page 8/18 datasheet and application eicedriver ? 2ED020I12-F 4 functional description 4.1 power supply the power supply of both sides, vsl and vsh, is monitored by an under-voltage lockout block (uvlo) which enables opera- tion of the corresponding side when the supply voltage reaches th e ?on? threshold of 12 v. afterwards the internal voltage reference and the biasing circuit are enabled. when the supply voltage (vsl, vsh) drops below the ?off? threshold of 11 v the circuit is disabled. 4.2 logic inputs the logic inputs inh, inl and /sd are fed in to schmitt-triggers with thresholds compatible to 3.3 v and 5 v ttl. when /sd is enabled (low), inh and inl are disabled. if inh is high (while inl is low), outh is enabled and vice versa. however, if both signals are high, they are internally disabled until both signals get low again. this is due to the interlocking logic of the d evice (see also figure 5). 4.3 gate driver 2ED020I12-F features two hard-switching gate drivers with n-c hannel output stages capable to source 1 a and to sink 2 a peak current. both drivers are equipped with active-low-clampi ng capability. furthermore, they feature a large ground bounce ruggedness in order to compensate ground bounces caused by a turn-off of the driven igbt. 4.4 general purpose operational amplifier this general purpose operational amplifier can be applied for cu rrent measurement of the driven low-side igbt. it is dedi- cated for fast operation with a gain of at least 10. the op is equipped with a -0.1 v to 2 v input stage and a rail-to-rail out put stage which is capable to drive 5 ma and is dedicated to drive an a/d converter. 4.5 general purpose comparator the general purpose comparator can be applied for over-current det ection of the low side igbt. a dedicated offset as well as a pull-up and pull-down resistor has been introduced to its inputs for security reasons. 4.6 clt in order to enable signal transmission across the isolation barri er between low-side and high-side driver, a coreless trans- former is employed. signals, that are to be transmitted, are specially encoded by th e transmitter and correspondingly restored by the receiver. in this way emi due to variations of gndh (dv gndh /dt) or the magnetic flux (d /dt) can be suppressed. to compensate the additional propagation delay of transmitter, core less transformer and receiver, a dedicated propagation delay is introduced into the low-side driver.
