STGAP2SCMTR

Isolators - Gate Drivers Overview

The STGAP2SCMTR is a galvanically isolated single gate driver from STMicroelectronics, designed for Silicon Carbide (SiC) MOSFETs. It features a high voltage rail up to 1700 V and provides a driver current capability of 4 A sink/source at 25°C. The device offers dV/dt transient immunity of ±100 V/ns across the full temperature range. It utilizes magnetic coupling for isolation and is housed in an SOIC-8 package.

Isolators - Gate Drivers Feature Summary

• Provides galvanic isolation between low-voltage control circuits and high-voltage power stages using magnetic coupling technology.
• Features a single output pin configuration with integrated Miller clamp functionality to prevent gate spikes during fast switching transitions in half-bridge topologies.
• Delivers 4 A peak source and sink current capability suitable for driving SiC MOSFETs efficiently.

Isolators - Gate Drivers Applications

• Industrial motor drives
• Power conversion systems
• High-power inverters

Isolators - Gate Drivers Procurement Notes

Verify the specific suffix 'CTR' indicates the tape-and-reel packaging format upon ordering. Confirm that the 1700 V rating aligns with the target SiC MOSFET voltage class. Ensure design compatibility with the SOIC-8 thermal requirements. Validate that the Miller clamp feature meets the noise immunity needs of the specific application topology before finalizing procurement.

Isolators - Gate Drivers Selection Notes

Select this component when a single-channel isolated driver with integrated Miller clamping is required for SiC applications. Choose the STGAP2SCMTR over the independent output variant if board space optimization and simplified external resistor networks are priorities. Ensure the 1700 V isolation rating exceeds the system's maximum bus voltage. Consider the 4 A drive strength sufficient for the target MOSFET gate charge requirements.

Isolators - Gate Drivers Part Context

The STGAP2SCMTR belongs to the STGAP2S family of isolated gate drivers. This series includes variants with independent outputs (STGAP2SICSTR) and those with Miller clamping (STGAP2SICSCTR). The family is designed for industrial applications requiring robust isolation and high-speed switching capabilities for wide-bandgap semiconductors.
