STGAP2HSCM

Isolators - Gate Drivers Overview

The STGAP2HSCM is a single-channel isolated gate driver from STMicroelectronics, designed for high-voltage power applications. It provides galvanic isolation between the low-voltage control circuitry and the high-side gate driving channel. The device supports a maximum voltage rating of up to 1700 V on the high-voltage rail. It delivers a peak source and sink current capability of 4 A at 25°C. The component features robust transient immunity with a common-mode rejection rate of ±100 V/ns across the full temperature range. It is housed in an 8-SO package.

Isolators - Gate Drivers Feature Summary

• Provides galvanic isolation between low-voltage control interfaces and high-voltage gate driving channels
• Delivers high peak drive current of 4 A for efficient switching of power devices
• Supports operation with high-voltage rails up to 1700 V
• Ensures signal integrity through high common-mode transient immunity

Isolators - Gate Drivers Applications

• Motor drive development using negative gate driving configurations
• High-voltage power conversion systems requiring reliable isolation

Isolators - Gate Drivers Procurement Notes

Verify the specific suffix 'H' in the part number STGAP2HSCM against official STMicroelectronics documentation to confirm it denotes the correct variant, as suffixes often indicate specific thermal or packaging characteristics. Ensure compatibility with the EVALSTGAP2HSCM demonstration board if hardware validation is required. Cross-reference the 8-SO package dimensions with your PCB layout constraints. Confirm that the 1700 V rating aligns with your system's voltage requirements before procurement.

Isolators - Gate Drivers Selection Notes

Select the STGAP2HSCM when designing circuits that require robust isolation for high-voltage switches operating up to 1700 V. Its 4 A drive current makes it suitable for medium-power applications where fast switching is necessary. Consider the 8-SO package size for space-constrained designs. Verify that the ±100 V/ns transient immunity meets the noise environment of your application. Compare with other members of the STGAP2 family if different drive currents or isolation voltages are needed.

Isolators - Gate Drivers Part Context

The STGAP2HSCM belongs to the STGAP2 series of isolated gate drivers from STMicroelectronics. This series is engineered for demanding power electronics applications, offering high reliability and performance. The 'H' suffix typically distinguishes this specific model within the lineup, potentially indicating variations in internal architecture or testing standards compared to other variants like the STGAP2SCM. These drivers are commonly used in industrial motor drives and renewable energy inverters.

Isolators - Gate Drivers Replacement Considerations

The STGAP2SCM is a related single gate driver within the same product family. However, verify if the 'H' suffix indicates distinct electrical or mechanical differences that would affect interchangeability. Direct substitution requires confirming pinout compatibility and ensuring the alternative meets the 1700 V and 4 A specifications.
