Pin Functionality
GND1
Ground connection of the input side.
/FLT (Fault output)
Open-drain with internal pull up resistor output to report a
desaturation error of the IGBT (/FLT is low if desaturation
occurs)
IN+ Non-inverting driver input
IN+ control signal for the driver output if IN- is set to low.
(The IGBT is on if IN+ = high and IN- = low)
A minimum pulse width is defined to make the IC robust
against glitches at IN+. An internal Pull-Down-Resistor
ensures IGBT Off-State.
IN- Inverting driver input
IN- control signal for driver output if IN+ is set to high.
(IGBT is on if IN- = low and IN+ = high)
A minimum pulse width is defined to make the IC robust
against glitches at IN-. An internal Pull-Up-Resistor ensures
IGBT Off-State.
/RST (Reset) input
Function 1: Enable/shutdown of the input chip. (The IGBT is
off if /RST = low). A minimum pulse width is defined to
make the IC robust against glitches at IN-.
Function 2: Resets the DESAT-FAULT-state of the chip if
/RST is low for a time T_RST. An internal Pull-Up-Resistor is
used to ensure FLT status output.
RDY (Ready status)
Open-drain with internal pull up resistor output to report the
correct operation of the device. (RDY = high if both chips are
above the UVLO level and the internal chip transmission is
faultless)
VCC1
5V power supply of the input chip
VEE2
Negative power supply pins of the output chip. If no negative
supply voltage is available, both pins have to be connected to
GND2.
DESAT (Desaturation)
Monitoring of the IGBT saturation voltage (V_CE) to detect
desaturation caused by short circuits. If OUT is high, V_CE is
above a defined value and a certain blanking time has
expired, the desaturation protection is activated and the
IGBT is switched off. The blanking time is adjustable by an
