Description:
The VLA503 is a hybrid
integrated circuit designed to
provide optimum gate drive
for IGBT modules. This device
provides high current optically
isolated gate drive with a large
output voltage swing. The driver
also provides short circuit
protection based on desaturation
detection.
Features:
£ Electrical Isolation Voltage
Between Input and Output
with Opto-coupler
(2500 Vrms for 1 Minute)
£ Two Supply Driver Topology
£ Built-in Short-Circuit Protection
(With a Pin for Fault Output)
£ TTL Compatible Input Interface
Application:
To drive IGBT modules for inverter
or AC servo systems applications
Recommended IGBT Modules:
600V module up to 600A
1200V module up to 1400A

Single Supply Operation
Notes:
(1) Power supply decoupling capacitors C1 and C2 should be connected as close as possible to the pins of the
gate driver and must be sized to have appropriate ESR and ripple current capability for the IGBT being driven.
(2) Ctrip should be connected as close as possible to the pins of the gate driver to avoid noise pick-up.
(3) All zener diodes 1W, all resistors 0.25W unless otherwise noted.

long enough so that the voltage on the detect Pin 1 is
greater than VSC at the end of the tTRIP delay the driver
will erroneously indicate that a short circuit has occurred.
To avoid this condition the VLA503 has provisions for
extending the tTRIP delay by connecting a capacitor
(CTRIP) between Pin 2 and VCC (Pins 4). The effect of
adding CTRIP on trip time is shown in Figure 3. If tTRIP
is extended care must be exercised not to exceed the
short-circuit withstanding capability of the IGBT mod-
ule. Normally this will be satisfied for Powerex NF and
A-Series IGBT modules as long as the total shut-down
time does not exceed 10µs.
