Overview
The DRV8316CTQRGFRQ1 is an automotive-grade, three-phase integrated FET motor driver from the DRV8316C-Q1 series. It features a single-chip power stage with three half-bridge drivers and supports PWM interfaces. The device operates within a supply voltage range of 4.5 V to 35 V, delivering up to 8 A peak output current per phase. It includes an internal 5.5 V regulator and functions reliably across temperatures from -40°C to +125°C. Packaged in a 40-pin VQFN (7x5 mm) with exposed pad for thermal management.
Feature Summary
- Integrated three-phase half-bridge power stage with low on-resistance MOSFETs
- Built-in 5.5 V linear regulator for gate drive and logic supply
- Supports PWM control interface for brushless DC motor applications
Applications
- Automotive brushless DC motor control systems
- Blower fan drives in HVAC units
- Electric fuel pump controllers
- Water pump actuators
Procurement Notes
Verify the 'T' suffix indicates tape-and-reel packaging configuration. Confirm Q1 designation aligns with AEC-Q100 qualification requirements. Ensure ordering part number matches exact package variant and temperature grade specified in official datasheets before procurement.
Selection Notes
Select this component when designing automotive BLDC motor drivers requiring integrated power stages. Verify input voltage compatibility with system rails between 4.5 V and 35 V. Consider thermal performance due to exposed pad design and ensure adequate PCB copper area for heat dissipation under peak load conditions.
Part Context
Part of Texas Instruments’ DRV8316C-Q1 family designed for robust automotive environments. Combines control logic and power MOSFETs into one compact solution. Targets high-efficiency, space-constrained motor control applications where reliability and integration are critical for mass production vehicles.
Replacement Considerations
Cross-reference with DRV8316CRGFRQ1 for non-tape variants or DRV8316CRRGFR for commercial versions. Ensure pinout and thermal characteristics match exactly. Validate functional equivalence only after confirming all electrical parameters against original specifications.
