The STMicroelectronics STGAP2SCMTR is a single-channel isolated gate driver built around magnetic coupling technology, delivering 1700 VDC galvanic isolation between the input logic and the output power stage. It is designed to drive IGBTs, SiC MOSFETs, and standard MOSFETs in half-bridge, full-bridge, and motor-drive topologies where a reinforced isolation barrier is required. The part provides 4 A peak source and sink current, which means it can charge and discharge the gate capacitance of large power switches fast enough to keep switching losses under control. The 100 V/ns common-mode transient immunity (CMTI) rating is the figure that determines whether the output stays latched when the switch node slews at high dV/dt — a critical parameter for SiC and GaN designs where switching edges can exceed 50 V/ns.
The magnetic coupling core sits inside the moulding, so there is no exposed paddle to solder; the eight pins carry all the thermal and electrical connections. For rework, the part lifts cleanly with hot air at 300°C for about 30 seconds — no hidden thermal pad to fight.
