VN340SP

Power Distribution Switches, Load Drivers Overview

The VN340SP is a monolithic quad high-side smart power solid-state relay developed using STMicroelectronics' VIPower technology. It is designed to drive four independent resistive or inductive loads with one side connected to ground. The device operates within a supply voltage range of 10 V to 36 V and features an operating output current capability. It utilizes a PowerSO-10 surface-mount package and supports an extended industrial temperature range from -55°C to +85°C.

Power Distribution Switches, Load Drivers Feature Summary

• Active current limitation prevents system power supply dropping during shorted load conditions
• Built-in thermal shutdown protects the chip from overtemperature and short-circuit events
• Open drain diagnostic output indicates overtemperature conditions for each channel
• Fast demagnetization capability for inductive loads

Power Distribution Switches, Load Drivers Applications

• Driving independent resistive loads
• Driving independent inductive loads
• Industrial control systems requiring high-side switching

Power Distribution Switches, Load Drivers Procurement Notes

Verify the specific suffix and packaging configuration, as the base part number may correspond to tube packaging while other variants use tape and reel. Confirm the exact operating temperature range and current rating against the datasheet, as these parameters vary between the standard VN340SP-E and the VN340SP-33-E variants. Ensure the component meets RoHS compliance requirements for the intended application.

Power Distribution Switches, Load Drivers Selection Notes

Select this component when a quad high-side driver with integrated protection is required for resistive or inductive loads. Consider the VN340SP-33-E variant if a higher operating output current of 1 A is needed compared to the standard 0.7 A. Verify that the PowerSO-10 package fits the PCB layout constraints and that the -55°C to +85°C temperature range suffices for the environmental conditions.

Power Distribution Switches, Load Drivers Part Context

The VN340SP belongs to the VN340 family of smart power relays from STMicroelectronics. It shares core functionality with the VN340SP-33-E but differs in current handling and potentially packaging. Other related parts include the VN330SP, which is a similar quad high-side driver but may have different specifications or status. The family utilizes VIPower technology for robust integration of drivers and protections.

Power Distribution Switches, Load Drivers Replacement Considerations

The VN340SP-33-E is a functional alternative within the same family, offering a 1 A output current instead of 0.7 A. Check pinout compatibility and thermal characteristics before substitution. No other direct cross-manufacturer replacements are confirmed in the provided data.
