VNI8200XPTR-32

Power Distribution Switches, Load Drivers Overview

The VNI8200XPTR-32 is an octal high-side smart power solid-state relay manufactured by STMicroelectronics. It features eight independent output channels with a maximum on-resistance of 200 mOhms and a per-channel current limit of 1.0 A. The device operates within a supply voltage range of 10.5 V to 36 V and supports selectable serial or parallel control interfaces. It includes integrated protection mechanisms such as active current limiting and channel-independent thermal shutdown, housed in a PowerSSO-36 surface-mount package.

Power Distribution Switches, Load Drivers Feature Summary

• Selectable serial (SPI) or parallel control interface for flexible system integration
• Integrated micropower step-down switching regulator providing up to 100 mA output current
• Built-in LED matrix driver circuitry for efficient status reporting of all eight outputs
• Active per-channel current limitation combined with independent thermal shutdown protection

Power Distribution Switches, Load Drivers Applications

• Industrial Programmable Logic Controller (PLC) digital output modules
• Smart factory automation systems requiring robust load driving
• Evaluation of power management and digital interface functionality
• Drivers for resistive, capacitive, or inductive loads connected to ground

Power Distribution Switches, Load Drivers Procurement Notes

Verify the specific suffix -32 to confirm the 1.0 A current limit variant, distinct from the standard VNI8200XP which has a 0.7 A limit. Ensure compatibility with the PowerSSO-36 footprint during PCB layout. Confirm that the selected interface mode aligns with the host controller's available SPI or parallel GPIO resources before finalizing the design.

Power Distribution Switches, Load Drivers Selection Notes

Select this component when an octal high-side switch with intelligent diagnostics is required. The VNI8200XPTR-32 is suitable for applications needing precise current limiting at 1.0 A per channel. Consider the integrated DC-DC regulator if external power for logic buffers is desired. Verify that the operating temperature range of -40 C to +125 C meets the environmental requirements of the target installation.

Power Distribution Switches, Load Drivers Part Context

This part belongs to the VIPower™ technology family designed for industrial applications. It is often paired with input drivers like the CLT01-38SQ7 in complete I/O solutions. Evaluation boards such as STEVAL-IFP032V1 are available to test its performance against industrial EMC standards including IEC 61000-4-2, -4, and -5.

Power Distribution Switches, Load Drivers Replacement Considerations

The VNI8200XP serves as a functional substitute but offers a lower 0.7 A current limit. For identical 1.0 A specifications, the IPS8200HQ series provides comparable octal high-side switching capabilities with similar diagnostic features.
