SST402 SOIC 8L

Overview

The SST402 is a high-speed, low-power MOSFET gate driver manufactured by Linear Integrated Systems. Designed for efficient power switching applications, it provides robust drive capability to minimize switching losses in power stages. The device operates within a specified voltage range and supports fast rise and fall times to ensure precise control of external MOSFETs or IGBTs. It is housed in an SOIC-8 surface-mount package, facilitating compact PCB layout and automated assembly processes suitable for modern electronic designs requiring reliable gate driving performance.

• Robust output drive strength for reliable MOSFET/IGBT control
• Surface-mount SOIC-8 packaging for compact integration

Applications

• DC-DC converter circuits
• Motor drive systems
• Inverter topologies
• Power supply management units

Procurement Notes

Verify the manufacturer designation as Linear Integrated Systems (LIS) or its successor entities, as LIS assets were acquired by Analog Devices. Confirm the specific suffix indicates the SOIC-8 package variant. Ensure the component meets required industrial temperature ranges if operating outside standard commercial limits. Cross-reference datasheets from authorized distributors to confirm pinout compatibility with existing designs.

Selection Notes

Select this component when high-speed gate driving is required with minimal quiescent current. Evaluate the peak output current requirements against the load capacitance of the target MOSFETs. Consider the SOIC-8 footprint constraints and thermal dissipation capabilities. Verify input logic voltage levels match the control circuitry. Compare propagation delay specifications against system timing requirements.

Part Context

Linear Integrated Systems was a semiconductor company known for precision analog and mixed-signal ICs. Its product lines, including gate drivers like the SST402, were integrated into broader portfolios following industry consolidations. The SST series typically denotes specialized signal processing or interface components. Understanding the lineage helps in identifying equivalent parts from current manufacturers holding the original IP rights.

Replacement Considerations

Check for direct equivalents from Analog Devices or other providers offering compatible SOIC-8 gate drivers. Verify pin-to-pin compatibility before substitution. Review updated datasheets for any changes in electrical characteristics or recommended operating conditions.
