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
