EiceDRIVER™ 1ED38x0Mc12M EnhancedDatasheet3 Pin configuration and functionalityFLT_Nfault output and fault-off input Open-drain output reports the failures related to operating of the inverter system to the microcontroller, fault output is active low. Fault-off input switch the gate driver output to off with fault-off function, input is low active. Connect to a microcontroller with 5 V or 3.3 V I/O with an external pull-up resistor to VCC1. A typical value for this resistor is 2.2 kΩ. The FLT_N signal is referenced to GND1. INnon inverting gate driver input IN input controls the output of the gate driver IC, the IGBT is turned on if IN is set to high. Connect to a PWM output of the microcontroller with 5 V or 3.3 V IO. An internal pull-down resistor ensures IGBT off-state if not connected. VEE2 Negative power supply terminal of the output side. Connect to a voltage of 0 V to -25 V referenced to GND2 for proper operation. Place a decoupling capacitor close to the following pins: • VCC2 and VEE2 • GND2 and VEE2 If no negative supply voltage is used, all VEE2 pins have to be connected to GND2. CLAMPMiller clamp output, Miller clamp pre-driver output, ADC input The function and operating mode of this pin is depending on the register configuration. High-current clamp output to hold the gate voltage low during collector-emitter-voltage rise. Connect directly to the gate of the IGBT. Clamp pre-driver output for the use of an external clamp switch. Connect directly to the gate of a n-channel MOSFET. Sensing input for 8-bit ADC. Connect the external signal source between CLAMP and VEE2. OFFdriver output High-current driver sink output to discharge the gate of the external IGBT and the two-level turn-off control output.The gate driver IC also sinks the Soft-off current at this pin. The pin is used as sense input for the gate high-level indicator PINSTAT .OFF_PIN and TLTOff comparator PINSTAT .TLTO_LVL. Connect to the gate of the IGBT via a chosen turn-off gate resistor. ONdriver output High-current driver source output to charge the gate of the external IGBT and turn it on and sense input for the CLAMP function. It is also the sense input for the gate low-level indicator PINSTAT .ON_PIN. Connect to the gate of the IGBT via a chosen turn-on gate resistor. DESATenhanced desaturation detection input Desaturation detection input to monitor the IGBT collector-emitter voltage (VCE) to detect desaturation caused by short circuit events. Connect to the collector of the driven IGBT via a series connection of a protection resistor and a high-voltage diode. The DESAT signal is referenced to GND2. VCC2 Positive power supply terminal of the output side. Connect to sufficient supply voltage referenced to GND2 for proper operation. Place a decoupling capacitor close to the following pins: • VCC2 and VEE2 • VCC2 and GND2 Datasheet 9 v2.0 2020-03-26 Document Outline Table of contents 1 Block diagram 2 Related products 3 Pin configuration and functionality 3.1 Pin configuration 3.2 Pin functionality 3.3 Configurable parameters via I2C 4 Functional description 4.1 Start-up and fault clearing 4.2 Supply 4.3 Input side logic 4.4 I2C bus 4.5 Operating states 4.6 Measurement 4.7 Monitoring 4.8 Desaturation protection 4.8.1 DESAT behavior 4.9 Gate driver output 4.9.1 Turn-on behavior 4.9.2 Turn-off and fault turn-off behavior 4.9.2.1 Hard switching turn-off 4.9.2.2 Two-level turn-off 4.9.2.3 Soft turn-off 4.9.3 Active shut-down 4.9.4 Active Miller clamp 4.10 Short circuit clamping 5 Electrical parameters 5.1 Absolute maximum ratings 5.2 Thermal parameters 5.3 Operating parameters 5.4 Electrical characteristics 5.4.1 Voltage supply 5.4.2 Logic input and output 5.4.3 Gate driver 5.4.4 Active Miller clamp 5.4.5 Dynamic characteristics 5.4.6 Desaturation protection 5.4.7 Two-level turn-off 5.4.8 Soft-off current source 5.4.9 Over-temperature protection 5.4.10 ADC measurement 6 Insulation characteristics 6.1 Certified according to VDE 0884-11 and IEC 60747-17 reinforced insulation (planned) 6.2 Recognized under UL 1577 (planned) 7 Package information Revision history Disclaimer
