Overview
The DRV8316CRQRGFRQ1 is an automotive-grade, three-phase integrated FET motor driver designed for driving 12V brushless DC motors. It features a peak output current of 8A and supports a supply voltage range of 4.5V to 35V, with a maximum absolute rating of 40V. The device integrates three half-bridge drivers with a low RDS(ON) of 95mΩ (high-side plus low-side). It operates within a temperature range of -40°C to +125°C and utilizes a VQFN-40 package.
Feature Summary
- Automotive-grade reliability compliant with AEC-Q100 standards
- Integrated power stage with ultra-low on-resistance for high efficiency
- Supports PWM interface for precise motor control
Applications
- Automotive brushless DC motor drives
- Solenoid actuation systems
- General automotive motion control applications
Procurement Notes
Verify the specific suffix 'Q1' confirms automotive qualification status. Ensure the ordering code matches the required tape-and-reel packaging configuration. Cross-reference the datasheet revision to confirm compatibility with existing design implementations. Confirm RoHS compliance status as per manufacturer specifications.
Selection Notes
Select this component when automotive certification is mandatory for BLDC applications. The integrated power MOSFETs simplify thermal management compared to discrete solutions. Consider the 8A peak current capability against load requirements. Verify that the VQFN-40 package fits the PCB layout constraints.
Part Context
This part belongs to the DRV8316C family of three-phase motor drivers from Texas Instruments. It shares architectural similarities with non-automotive variants but includes enhanced durability and documentation for automotive environments. The Q1 suffix distinguishes it as a qualified automotive product.
Replacement Considerations
DRV8316CTQRGFRQ1 offers parameter equivalence with additional integrated current detection capabilities. Verify if the extra diagnostic features are required or if the standard DRV8316CRQRGFRQ1 suffices for the application.
