Product details
Overview
DRV8316RQRGFRQ1 from Texas Instruments is an AEC-Q100 Grade 1 qualified three-phase BLDC motor driver IC with integrated 40-V FETs, 95-mΩ total RDS(ON), 8-A peak output current, and support for 200-kHz PWM operation - designed for automotive 12-V, <40-W motor modules including LIDAR actuators and small fans.
For engineers reviewing the DRV8316RQRGFRQ1 datasheet, DRV8316RQRGFRQ1 pinout, DRV8316RQRGFRQ1 application, or DRV8316RQRGFRQ1 equivalent, key selection criteria include integrated current sensing (no external shunts), dual-regulator power management (3.3-V/30-mA LDO + 3.3/5-V/200-mA buck), hardware/SPI interface flexibility, and comprehensive fault diagnostics via nFAULT and SPI.
Technical Context
The DRV8316RQRGFRQ1 implements a configurable 6x or 3x PWM control scheme supporting sensored/sensorless FOC, sinusoidal, and trapezoidal commutation. Its gate drivers feature programmable slew rate (4-level hardware setting) and 500–3400 ns dead-time control to minimize shoot-through risk across operating conditions.
Integrated protection includes supply UVLO (4.2–4.4 V trip), charge pump undervoltage detection, cycle-by-cycle current limiting with 5-µs blanking, thermal warning/shutdown (OTW/OTSD), and overcurrent protection - all signaled via open-drain nFAULT or optional SPI diagnostics.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Operating Voltage | 4.5 V to 35 V (40 V abs max); supports full automotive battery range including cold-crank transients. |
| Peak Output Current | 8 A per phase; enables direct drive of compact BLDC motors up to 40 W without external current amplification. |
| RDS(ON) (HS+LS) | 95 mΩ at 25°C; minimizes conduction loss and thermal stress in high-efficiency motor control stages. |
| Sleep Current | 1.5 µA at 24 V; extends battery life in always-on automotive subsystems like HVAC actuators. |
| PWM Frequency Support | Up to 200 kHz; allows precise control of low-inductance motors used in LIDAR scanning and fast-response pumps. |
| Current Sensing | Integrated amplifier with 0.15–1.2 V/A gain range; eliminates need for external sense resistors and PCB area. |
| Regulators | Built-in 3.3-V/30-mA LDO + 3.3/5-V/200-mA buck; powers internal logic and external MCU/peripherals from VM rail. |
Pinout & Package
The DRV8316RQRGFRQ1 is housed in a thermally enhanced 40-pin VQFN package (7.0 mm × 5.0 mm) with exposed thermal pad connected to AGND for optimal heat dissipation in automotive environments.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| INHA, INHB, INHC | High-side control inputs | Direct PWM signals to enable/disable high-side FETs; compatible with 1.8/3.3/5-V logic levels. |
| INLA, INLB, INLC | Low-side control inputs | Direct PWM signals to enable/disable low-side FETs; support independent or complementary drive schemes. |

| nFAULT | Fault indicator output | Open-drain signal pulled low on UVLO, OCP, OTSD, or CPUV; requires external pull-up to 1.8–5.0 V. |
| nSLEEP | Sleep mode control | Logic-low entry into ultra-low-power sleep (1.5 µA); 20–40 µs pulse resets faults without sleep transition. |
| VREF/ILIM | Reference/current limit input | Configures current-sense reference voltage (PWM Modes 1/3) or sets cycle-by-cycle ILIM threshold (Modes 2/4). |
| SOA, SOB, SOC | Current sense outputs | Analog outputs proportional to phase current (±8 A full-scale); gain set by GAIN pin or SPI register. |
| AVDD | Analog regulator output | 3.3-V ±5% regulated supply (30 mA max); powers internal analog circuitry and external sensors. |
| VM (pins 9–11) | Main power input | Motor supply connection; bypassed with dual 0.1-µF ceramics + bulk capacitor; supports 4.5–35 V operation. |
| PGND (pins 12,15,18) | Power ground | High-current return path for motor phases; separate from AGND to reduce noise coupling into analog circuits. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar three-phase BLDC motor driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DRV8323RSRTVTQ1 | Higher 65-V abs max rating; 12-A peak current; SPI-only interface; no hardware PWM option. | Better suited for 24-V/48-V industrial or commercial BLDC systems; lacks direct 3x/6x PWM pin compatibility. | Select when higher voltage headroom or greater current capability is required, and SPI control is acceptable. |
| MP6532GQ-Z | Non-AEC-Q100; 36-V max; 5-A peak; integrated current sense; 1.8-V logic compatible. | Targeted at consumer/industrial BLDC drives; not qualified for automotive temperature or reliability requirements. | Consider only for non-automotive designs where AEC-Q100 compliance is unnecessary and cost sensitivity is high. |
Compared with DRV8323RSRTVTQ1 and MP6532GQ-Z, the DRV8316RQRGFRQ1 uniquely balances AEC-Q100 Grade 1 qualification, dual-interface flexibility (hardware PWM + SPI), and integrated power management - making it optimal for cost-constrained, space-limited 12-V automotive motor modules requiring functional safety awareness.

FAQ
What is the absolute maximum voltage rating for the DRV8316RQRGFRQ1 VM pin?
The DRV8316RQRGFRQ1 VM pin has an absolute maximum rating of 40 V. Operation above this voltage risks permanent device damage. The recommended operating range is 4.5 V to 35 V, covering standard automotive battery conditions including load-dump transients. This 40-V rating enables robustness against transient overvoltage events common in vehicle electrical systems, and is validated under AEC-Q100 stress testing protocols for the DRV8316RQRGFRQ1.
Does the DRV8316RQRGFRQ1 require external current sense resistors?
No, the DRV8316RQRGFRQ1 does not require external current sense resistors. It integrates a precision current sense amplifier with selectable gain (0.15–1.2 V/A) and ±8-A full-scale range, delivering analog outputs (SOA/SOB/SOC) directly proportional to phase current. This eliminates board space, BOM cost, and thermal drift errors associated with external shunts - a confirmed design feature of the DRV8316RQRGFRQ1 per its functional description and electrical characteristics table.
How does the DRV8316RQRGFRQ1 support both sensored and sensorless motor control?
The DRV8316RQRGFRQ1 supports both sensored and sensorless BLDC control through its configurable 6x or 3x PWM interface. In 6x mode, independent high- and low-side inputs allow commutation based on Hall sensor feedback. In 3x mode, complementary PWM pairs enable sensorless FOC or trapezoidal control using back-EMF estimation - all implemented externally by the host MCU. This dual-mode capability is explicitly documented in the DRV8316RQRGFRQ1 datasheet's Description and Feature sections.
What protection features are integrated into the DRV8316RQRGFRQ1?
The DRV8316RQRGFRQ1 integrates supply UVLO (4.2–4.4 V), charge pump undervoltage (CPUV), cycle-by-cycle overcurrent protection (OCP), thermal warning/shutdown (OTW/OTSD), and fault indication via nFAULT pin. Optional SPI-based diagnostics provide additional visibility. All protections are hardware-implemented and active during normal operation - confirmed in the Features, Description, and Electrical Characteristics sections of the DRV8316RQRGFRQ1 datasheet.
Can the DRV8316RQRGFRQ1 power external circuitry?
Yes, the DRV8316RQRGFRQ1 can power external circuitry. Its integrated 3.3-V/30-mA LDO (AVDD) and 3.3/5-V/200-mA buck regulator (BKOUT) provide regulated supplies for microcontrollers, sensors, or communication interfaces. Output voltages are configurable via hardware pins (VSEL_BK, MODE) or SPI registers, and load capabilities are specified across temperature and input voltage ranges in the DRV8316RQRGFRQ1 electrical characteristics table.
