BD16950AEFV-CE2

Gate Driver Overview

The BD16950AEFV-CE2 is an automotive-grade, AEC-Q100 qualified 2-channel half-bridge gate driver manufactured by ROHM Semiconductor. It is designed for independent control of low-side and high-side N-MOSFETs via a 16-bit Serial Peripheral Interface (SPI) controlled by an external microcontroller unit. The device operates within a supply voltage range of 3 V to 5.5 V and supports junction temperatures from -40°C to +125°C. Packaged in a 24-HTSSOP-B surface-mount format with exposed pads, it features a maximum propagation delay of 400 ns and is classified as Not Recommended for New Designs.

Gate Driver Feature Summary

• Independent control of low-side and high-side N-MOSFETs through a 16-bit SPI interface managed by an external MCU.
• Automotive qualification compliant with AEC-Q100 standards for reliability in vehicle environments.
• Integrated protection mechanisms including thermal shutdown and under-voltage lockout to ensure safe operation.

Gate Driver Applications

• Automotive power management systems requiring isolated gate driving capabilities.
• Motor control applications utilizing N-channel MOSFET configurations.
• Industrial inverters and converters operating within specified voltage limits.

Gate Driver Procurement Notes

Verify the current lifecycle status before procurement, as this component is designated as Not Recommended for New Designs. Confirm that existing inventory meets project requirements or plan for alternative sourcing strategies. Ensure compatibility with the 24-HTSSOP-B package dimensions and verify SPI communication protocols with the host microcontroller. Check for moisture sensitivity level constraints during storage and handling procedures.

Gate Driver Selection Notes

Select this component only if the design already incorporates the BD16950AEFV-CE2 or requires specific legacy compatibility. Evaluate the 16-bit SPI interface requirement against available microcontroller resources. Consider the limited supply chain stability due to the NRND status when finalizing the bill of materials. Assess thermal performance within the 24-HTSSOP-B package for the intended application load.

Gate Driver Part Context

This part belongs to the BD16950 series of half-bridge gate drivers from ROHM Semiconductor. It shares functional similarities with other automotive-grade drivers but is distinct in its specific SPI configuration and package type. The series targets robust motor control and power switching applications in demanding automotive environments.

Gate Driver Replacement Considerations

BD16952EFV-ME2 is listed as a direct substitute option. Verify pinout compatibility and electrical specifications before substitution. Note that the replacement may have different packaging or lifecycle statuses.
