EiceDRIVER™ 1ED34x1Mc12M Enhanced Datasheet 3 Pin configuration and functionality VCC1
Positive power supply terminal of the input side, connect to 5 V or 3.3 V for proper operation. Place a decoupling capacitor close to this pin and GND1.
ADJA and ADJB parameter adjust input for set A or B
The pins ADJA and ADJB are used to adjust two sets of independent parameters of output functions. Connect a resistor between 1.33 kΩ and 28.0 kΩ to GND1 to adjust each parameter. All valid resistor values belong to the E96-series with 1% tolerance. Connecting ADJA to GND1 uses a default value for soft switch-off. Connecting it to VCC1 is disabling the gate driver IC. Connecting ADJB to GND1 is disabling the gate driver IC. Connecting it to VCC1 is setting the function to minimum values.
RDYC ready status output, fault-off input and fault-clear input
Open-drain output reports the correct operation of the device, ready output is high active. Fault-clear input and fault-off input clears a gate driver fault or 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 RDCY signal is referenced to GND1.
FLT_N fault 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.
IN non 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. A minimum pulse width of typical 103 ns is defined to make the gate driver IC robust against glitches at IN.
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.
CLAMP Miller clamp output, CLAMPDRV Miller clamp pre-driver output
CLAMP: High-current clamp output to hold the gate voltage low during collector-emitter-voltage rise. Connect directly to the gate of the IGBT. CLAMPDRV: Clamp pre-driver output for the use of an external clamp switch. Connect directly to the gate of a n- channel MOSFET.
OFF driver output
High-current driver sink output to discharge the gate of the external IGBT.The gate driver IC also sinks the Soft- off current at this pin. Connect to the gate of the IGBT via a chosen turn-off gate resistor.
