Description:
VLA502-01 is a hybrid integrated
circuit designed for driving IGBT
modules. This device is a fully
isolated gate drive circuit consisting of an optimally isolated gate
drive amplifier and an isolated
DC-to-DC converter. The gate
driver provides an over-current
protection function based on
desaturation detection.
Features:
£ Built-in Isolated DC-DC
Converter for Gate Drive
£ Propagation Delay Time:
0.4 µs (Typical)
£ SIP Outline Allows More Space
on Mounting Area
£ Variable Fall Time on ShortCircuit Protection
£ Electrical Isolation Voltage
Between Input and Output
(2500 Vrms for 1 Minute)
£ CMOS, TTL Compatible Input
Application:
To drive IGBT modules for inverter
or AC servo systems applications
Recommended IGBT Modules:
600V and 1200V NFH Series
IGBTs
Note: All dimensions listed are maximums except E.
