HYBRID IC
VLA526A-06AR
Hybrid IC for driving IGBT modules
DESCRIPTION
The VLA526A-06AR is the 6-element gate driver for a

Dimensions: mm
400VAC 3 phase inverter. 3 circuits of high side are isolated
between input and output and the power supplies consist of the

inside. This Hybrid IC can be driven by input voltage of 2 lines
(+15V and +5V). By connecting the resistor for current detection
between B-N, this Hybrid IC can detect an over-current, and can
cut off each gate signal.
The low side of an input part has a timing revision circuit that
can revise time lag with the signal of high side and this hybrid IC
can realize the optimum inverter drive.
Recommended IGBT module: V_CES=1200V/ up to 25A class

•Supply voltage ···································+5V, +15V
•High side isolation voltage············· 2500Vrms, for 1 min
•The power supply for a high side gate drive and the electrolysis capacitor for voltage compensation are unnecessary.
•SIL structure, 6-circuit driver built-in, it saves area on mother board.
•Recommended switching frequency range is up to 3kHz.
APPLICATIONS
IGBT drive for 3 phase inverter etc.
