Overview
The BD16939AEFV-CE2 is an automotive-grade, AEC-Q100 qualified 6-channel half-bridge gate driver manufactured by ROHM Semiconductor. Designed for brushed DC motor applications, it integrates independent control of low-side and high-side N-MOSFETs via a 16-bit Serial Peripheral Interface (SPI) from an external MCU. The device supports High, Low, and Hi-Z output modes for each channel. It operates within a supply voltage range of 6.3 V to 32 V and delivers a maximum output current of 1 A per channel. Key protection features include over-current protection, under-voltage lockout, thermal shutdown, and reverse voltage protection diodes.
Feature Summary
- Six-channel half-bridge architecture with independent MOSFET control
- 16-bit SPI interface for external MCU command integration
- Three-mode output capability: High, Low, and High Impedance states
- Comprehensive protection suite including OCP, UVLO, TSD, and reverse voltage diodes
Applications
- Automotive brushed DC motor drives
- Vehicle motion control systems
- Ignition controller circuits
Procurement Notes
Verify the specific suffix CE2 against the official datasheet to confirm package type and tape-and-reel specifications. Confirm AEC-Q100 Grade 1 qualification status for your target automotive environment. Check for End-of-Life or Not Recommended for New Design (NRND) status in current manufacturer bulletins before finalizing procurement plans.
Selection Notes
Select this component when a multi-channel solution is required for driving multiple brushed DC motors from a single IC. Ensure the design accommodates the 16-bit SPI communication protocol and that the system voltage remains within the 6.3 V to 32 V operating window. Verify that the HTSSOP-B28 package dimensions fit the PCB layout constraints.
Part Context
This part belongs to ROHM's automotive motor driver family, specifically designed for high-reliability vehicle applications. It complements other half-bridge drivers like the BD16938AEFV series but offers a distinct 6-channel configuration optimized for complex motion control tasks requiring integrated logic and power stages.
Replacement Considerations
The BD16938AEFV-C is listed as an alias or related variant in some documentation; verify pin compatibility and channel count differences before substitution. No direct public substitute part numbers are confirmed in the provided source material.
