STGAP2SICSC

Isolators - Gate Drivers Overview

The STGAP2SICSC is a single-channel, galvanically isolated gate driver designed for Silicon Carbide (SiC) MOSFETs. It provides 4 A sink/source current capability and supports high-voltage rails up to 1200 V. The device features a wide-body SO-8W package with 5 kVrms insulation voltage and ±100 V/ns Common Mode Transient Immunity (CMTI). Key electrical parameters include a maximum propagation delay of 90 ns, rise/fall times of 30 ns, and an operating temperature range from -40°C to +125°C. It integrates UVLO and thermal shutdown protection.

Isolators - Gate Drivers Feature Summary

• Provides galvanic isolation between the gate driving channel and low-voltage control circuitry.
• Integrates Miller clamp function to prevent gate spikes during fast commutations in half-bridge topologies.
• Features dual input pins allowing selection of signal polarity and hardware interlocking protection.
• Includes UVLO optimized for SiC MOSFETs and thermal shutdown for system reliability.

Isolators - Gate Drivers Applications

• Industrial power conversion systems
• Motor driver inverters
• High-frequency switching applications requiring SiC MOSFET control

Isolators - Gate Drivers Procurement Notes

Verify the specific suffix 'C' indicates the Wide Body SO-8W package configuration. Confirm that the required insulation certification meets project standards, as the device carries IEC 60747-17 certification and UL 1577 recognition. Ensure the design accounts for the 5 kVrms isolation rating and the specific pinout of the wide-body package to avoid layout errors during integration.

Isolators - Gate Drivers Selection Notes

Select this component when driving SiC MOSFETs in half-bridge configurations requiring integrated Miller clamp protection. The 4 A drive strength suits medium-to-high power industrial applications. Consider the wide-body SO-8W package for enhanced creepage distances if higher isolation robustness is needed compared to standard SO-8 packages.

Isolators - Gate Drivers Part Context

This part belongs to the STGAP2SICS family of isolated gate drivers. It is specifically configured with a single output pin and Miller clamp functionality, distinguishing it from variants like the STGAP2SICSTR which offer separate sink/source pins for independent optimization. The 'C' suffix denotes the wide-body packaging variant.

Isolators - Gate Drivers Replacement Considerations

Direct substitutes within the same family include STGAP2SICS (standard SO-8) or STGAP2SICSTR (separate output pins). Verify package compatibility and pinout differences before substitution, as the wide-body SO-8W footprint differs from standard SO-8.
