Pin Configuration and Functionality
A minimum pulse width is defined to make the IC robust against glitches at IN+. An internal Pull-Down-Resistor ensures
IGBT Off-State.
INLS- Inverting driver input (Low side)
INLS- control signal for driver output if INLS+ is set to high. (IGBT is on if INLS- = low and INLS+ = high)
A minimum pulse width is defined to make the IC robust against glitches at INLS-. An internal Pull-Up-Resistor ensures
IGBT Off-State.
/RSTLS (Reset input Low side)
Function 1: Enable/shutdown of the input chip. (The IGBT is off if /RSTLS = low). A minimum pulse width is defined to
make the IC robust against glitches at INLS-.
Function 2: Resets the DESAT-FAULT-state of the chip if /RSTLS is low for a time T
. An internal Pull-Up-Resistor is
RST
used to ensure /FLTLS status output.
/FLTLS (Fault output Low side)
Open-drain output to report a desaturation error of the IGBT (/FLTLS is low if desaturation occurs)
RDYLS (Ready status Low side)
Open-drain output to report the correct operation of the device. (RDYLS = high if both chips are above the UVLO level and
the internal chip transmission is faultless)
VCC1LS (Low side)
5V power supply of the input chip
VEE2LS (Low side)
Negative power supply pins of the output chip. If no negative supply voltage is available, both pins have to be connected to
GND2LS.
DESATLS (Desaturation Low side)
Monitoring of the IGBT saturation voltage (V
) to detect desaturation caused by short circuits. If OUT is high, V
is above
CE
CE
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 external capacitor.
CLAMPLS (Clamping)
Ties the gate voltage to ground after the IGBT has been switched off at a defined voltage to avoid a parasitic
switch-on of the IGBT.During turn-off, the gate voltage is monitored and the clamp output is activated when the
gate voltage goes below 2V (related to VEE2LS).
GND2LS (Low side)
Reference ground of the output chip.
OUTLS (Driver output Low side)
Output pin to drive an IGBT. The voltage is switched between VEE2LS and VCC2LS. In normal operating mode Vout is
controlled by INLS+, INLS- and /RSTLS. During error mode (UVLO, internal error or DESATLS Vout is set to VEE2LS
independent of the input control signals.
VCC2LS (Low side)
Positive power supply pin of the output side.
