STMicroelectronics STGAP3S6I
STGAP3S6I - Galvanically isolated gate driver for IGBTs with 6 A Source/Sink current, desaturation protection and adjustable SOFTOFF
The STGAP3S is a family of protected single gate drivers that provides galvanic isolation between the gate driving channel and the low voltage control and interface circuitry.
The platform includes different options with 10 A and 6 A current capability, each of which is available with dedicated UVLO variants for SiC MOSFETs and IGBTs.
Ultrafast desaturation protection is also available with differentiated intervention thresholds and adjustable soft turn-off.
The availability of the Miller CLAMP and optional negative driving enables optimal driving performance.
