Description:
The VLA503-01 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
£ Two Supply Driver Topology
£ Built-in Short-Circuit Protection
£ 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 400A
VLA503-01
Hybrid IC
IGBT Gate Driver
Between Input and Output
with Opto-coupler
(2500 V rms for 1 Minute)
(With a Pin for Fault Output)
