VNQ810MTR-E

Power Distribution Switches, Load Drivers Overview

The VNQ810MTR-E is a quad-channel high-side power driver manufactured by STMicroelectronics, designed for load switching applications. It features an N-channel output configuration with four independent channels, each capable of delivering up to 900mA maximum output current. The device operates within a load voltage range of 5.5V to 36V and supports a junction temperature range of -40°C to 150°C. Packaged in a 28-SOIC surface-mount enclosure, it integrates comprehensive protection mechanisms including over-temperature shutdown, over-voltage protection, fixed current limiting, and open-load detection. The component utilizes a non-inverted on/off interface without requiring a separate supply voltage.

Power Distribution Switches, Load Drivers Procurement Notes

Verify the exact suffix designation, as the base part number VNQ810 may refer to variants with different packaging or thermal characteristics. Confirm that the specific model VNQ810MTR-E matches the required tape-and-reel format if automated assembly is planned. Check for RoHS compliance status updates, as older datasheets may indicate non-compliance while newer revisions might differ. Ensure the supplier provides authentic STMicroelectronics documentation to validate the pinout and electrical parameters against the official datasheet before integration.

Power Distribution Switches, Load Drivers Selection Notes

Select this component when a quad-channel solution is required for high-side switching within a 36V system. Consider the 900mA per channel limit for load sizing and ensure the PCB layout supports the thermal dissipation needs of the SOIC package. Evaluate the need for open-load diagnostics; if not required, simpler drivers may be more cost-effective. Verify that the operating temperature range meets the environmental constraints of the target application, particularly regarding the 150°C junction limit under high load conditions.

Power Distribution Switches, Load Drivers Part Context

The VNQ810 series belongs to STMicroelectronics' family of smart high-side power switches designed for automotive and industrial markets. These devices integrate power MOSFETs with control logic and protection circuits to simplify system design. The quad-channel architecture allows for compact implementation in space-constrained applications where multiple independent loads must be controlled and monitored. This specific variant emphasizes reliability through extensive fault protection features common in modern power management ICs.

Power Distribution Switches, Load Drivers Replacement Considerations

Direct substitutes include other quad-channel high-side drivers from STMicroelectronics such as the L298N series or similar multi-channel power switches from competitors like Infineon or Texas Instruments. Ensure replacement parts match the 28-SOIC footprint and voltage/current ratings. Verify compatibility with existing control logic levels and protection feature requirements before swapping components.
