VLA504-01

Gate Driver Overview

The VLA504-01 is a hybrid integrated circuit designed for driving n-channel IGBT modules in gate-amplifier applications. It functions as a fully isolated gate drive circuit featuring an optically isolated amplifier with desaturation-based over-current protection. The device operates within a supply voltage range of 14 V to 17 V and provides single-channel low-side drive capability. It delivers peak output currents of 5 A for both sourcing and sinking. Typical switching characteristics include rise and fall times of 400 ns and 300 ns, respectively. The component supports non-inverting input logic and is housed in a 14-SIP module package with 12 leads for through-hole mounting.
