1ED020I12FTA
Single IGBT Driver IC
Pin Configuration and Functionality
VCC1
5 V power supply of the input chip
VEE2
Negative power supply pins of the output chip. If no negative supply voltage is available, all VEE2 pins have to
be connected to GND2.
DESAT Desaturation Detection Input
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 external capacitor.
CLAMP Miller 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 2 V below VEE2.
GND2 Reference Ground
Reference ground of the output chip.
OUT Driver Output
Output pin to drive an IGBT. The voltage is switched between VEE2 and VCC2. In normal operating mode Vout
is controlled by IN+, IN- and /RST. During error mode (UVLO, internal error or DESAT) Vout is set to VEE2
independent of the input control signals.
VCC2
Positive power supply pin of the output side.
TLSET Two Level Turn Off Adjust
Circuitry at TLSET adjust the two level turn off time with an external capacitor to GND2 and the two level
voltage with an external Zener diode to GND2, for wave forms please see Figure 7-4.
