commutation. The schmitt-trigger input threshold
of them are such to guarantee LSTTL and CMOS
compatibility down to 3.3V controller outputs.
Figure 3: Input pin structure
An internal pull-up resistor of about 75 kΩ is pre-
biases the input during supply start-up and a
zener clamp is provided for pin protection
purposes. Input schmitt-trigger and noise filter
provide beneficial noise rejection to short input
pulses according to Figure 4 and Figure 7.
It is anyway recommended for proper work of the
driver not to provide input pulse-width lower than
1us.
The 6ED003L06-F provides additionally an anti-
shoot through prevention capability which avoids
the simultaneous on-state of two gate drivers of
the same leg (i.e. HO1 and LO1, HO2 and LO2,
HO3 and LO3). When two inputs of a same leg
are activated, only one leg output is activated, so
that the leg is kept steadily in a safe state. Please
refer to the application note AN-Gatedrive-
6ED003L06-1 for a detailed description.
A minimum deadtime insertion of typ 380ns is also
provided, in order to reduce cross-conduction of
the external power switches.
EN (Gate driver enable, Pin 10)
The signal applied to pin EN controls directly the
output stages. All outputs are set to LOW, if EN is
at LOW logic level. The internal structure of the
pin is the same as Figure 3 made exception of the
switching levels of the Schmitt-Trigger, which are

/Fault pin is an active low open-drain output
indicating the status of the gate driver (see Figure
3). The pin is active (i.e. forces LOW voltage
level) when one of the following conditions occur:

detection function, Pin 9, 11)
6ED003L06-F provides an over-current detection
function by connecting the ITRIP input with the
motor current feedback. The ITRIP comparator
threshold (typ 0.46V) is referenced to VSS
ground. A input noise filter (typ: t
prevents the driver to detect false over-current
events.
Over-current detection generates a hard shut
down of all outputs of the gate driver and provides
a latched fault feedback at /FAULT pin.
RCIN input/output pin is used to determine the
reset time of the fault condition. As soon as ITRIP
threshold is exceeded the external capacitor
connected to RCIN is fully discharged. The
capacitor is then recharged by the RCIN current
generator when the over-current condition is
finished. As soon as RCIN voltage exceeds the

VCC is the low side supply and it provides power
both to input logic and to low side output power
stage. Input logic is referenced to VSS ground as
well as the under-voltage detection circuit. Output
power stage is referenced to COM ground.COM
ground is floating respect to VSS ground with a
recommended range of operation of +/-2.5V. A

from noise spikes.
