VN330SP

Power Distribution Switches, Load Drivers Overview

The VN330SP is a monolithic high-side solid-state relay developed using STMicroelectronics' VIPower technology. It integrates four independent N-channel drivers in a PowerSO-10 package, designed to control resistive or inductive loads connected to ground. The device operates within a supply voltage range of 10 V to 36 V and supports an output current of up to 700 mA per channel. Key electrical parameters include a maximum on-resistance of 200 mΩ, rise time of 50 µs, fall time of 8 µs, and open delay of 40 µs. It functions across a junction temperature range of -40°C to +125°C.

Power Distribution Switches, Load Drivers Feature Summary

• Integrates four independent high-side switches for driving resistive or inductive loads
• Includes active current limiting to prevent system power supply drops during short circuits
• Features built-in thermal shutdown and undervoltage protection mechanisms
• Provides open-drain diagnostic output to indicate overtemperature conditions

Power Distribution Switches, Load Drivers Applications

• Industrial automation systems requiring IEC 61131-2 compliance
• Control of solenoids, lamps, and heaters in automotive environments
• General-purpose load switching in embedded power management circuits

Power Distribution Switches, Load Drivers Procurement Notes

Verify the specific suffix (e.g., SP vs. SP-E) as it determines packaging and lifecycle status. The VN330SP without the E suffix may be obsolete; confirm availability with authorized distributors. Ensure RoHS compliance requirements match the specific revision. Check moisture sensitivity levels and storage conditions before procurement.

Power Distribution Switches, Load Drivers Selection Notes

Select this component when four independent high-side outputs are required in a compact surface-mount package. Compare against the VN340 series if higher current capacity (1 A) or different pin configurations are needed. Consider the VN330SP-E variant for updated environmental compliance and active production status. Evaluate thermal dissipation requirements based on the 200 mΩ on-resistance.

Power Distribution Switches, Load Drivers Part Context

The VN330SP belongs to the VN330 family of smart power devices from STMicroelectronics. These components utilize VIPower technology to combine logic and power stages on a single silicon die. The family is designed for robust performance in harsh electromagnetic and thermal environments typical of industrial and automotive applications.

Power Distribution Switches, Load Drivers Replacement Considerations

The VN330SP-E is the direct successor with updated specifications and packaging options. For higher current needs, consider the VN340SP-33-E. Verify pin compatibility and thermal characteristics when substituting older revisions with newer E-series variants.
