Overview
The BD6973FV-E2 is a bipolar motor driver integrated circuit manufactured by ROHM Semiconductor, designed for fan and motor control applications. It operates within a supply voltage range of 4.3 V to 17 V and features an NMOS output structure. The device is housed in a 16-SSOP-B package with dimensions of 0.173 inches (4.40 mm) width. It supports a maximum power dissipation of 874.7 mW and functions reliably across an operating temperature range from -40°C to +100°C. This component belongs to the PMIC category under Motor / Motion / Ignition Controllers & Drivers.
Feature Summary
- Bipolar motor driver architecture utilizing NMOS output technology for efficient load switching.
- Integrated design suitable for direct fan and motor control without external complex circuitry.
- Wide operational voltage tolerance supporting various low-voltage electronic systems.
Applications
- Fan motor control circuits
- Motion control systems
- Ignition controller drivers
Procurement Notes
Verify the specific suffix E2 against the manufacturer's latest datasheet to confirm pinout compatibility and environmental compliance status. Ensure the SSOP-B-16 package footprint matches the target PCB layout requirements. Confirm that the 4.3 V minimum operating voltage aligns with the system's power rail stability under all load conditions before final integration.
Selection Notes
Select this component when a compact bipolar driver with NMOS outputs is required for low-to-medium power motor loads. Consider the 16-pin SSOP-B package constraints for space-limited designs. Evaluate the 874.7 mW thermal dissipation capability against the expected ambient temperature and heat sinking options to ensure reliable operation within the specified -40°C to +100°C range.
Part Context
This part is categorized under Power Management ICs, specifically within the Motor / Motion / Ignition Controllers & Drivers subcategory. It is part of a family of fan motor controllers produced by ROHM Semiconductor. The BD6973FV-E2 shares functional similarities with related models like the BD6971FV-E2 and BD6974FV-E2, differing primarily in package configuration and specific electrical thresholds defined by the manufacturer.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Cross-reference with BD6971FV-E2 or BD6974FV-E2 only if electrical parameters and package types are verified as compatible through official ROHM Semiconductor engineering data.
