VLA526A-06AR

HYBRID IC VLA526A-06AR Hybrid IC for driving IGBT modules DESCRIPTION The VLA526A-06AR is the 6-element gate driver for a OUTLINE DRAWING Dimensions: mm 400VAC 3 phase inverter. 3 circuits of high side are isolated between input and output and the power supplies consist of the 88.0MAX Mark inside. This Hybrid IC can be driven by input voltage of 2 lines (+15V and +5V). By connecting the resistor for current detection 41.5MAX 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: VCES=1200V/ up to 25A class FEATURES 2.54 7.5MAX 30 0.5 +0.15/-0.1 7.5MAX 1 4.0MAX 3.5+/-0.7 0.25 +0.2/-0.1 9.5MAX 13.0MAX 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.
