Product details
Overview
DRV8316CTQRGFRQ1 from Texas Instruments is an AEC-Q100 Grade 1 automotive three-phase BLDC motor driver IC with integrated 40-V FETs, 95-mΩ (HS+LS) RDS(ON), 8-A peak output current, and hardware-pin-based configuration. It supports up to 200-kHz PWM, built-in current sensing, and active demagnetization for small automotive fans, pumps, and actuators.
For engineers reviewing the DRV8316CTQRGFRQ1 datasheet, DRV8316CTQRGFRQ1 pinout, DRV8316CTQRGFRQ1 application, or DRV8316CTQRGFRQ1 equivalent, key selection considerations include its 40-pin VQFN package, 4.5–35-V operating range, 3.3/5-V buck regulator, 3.3-V LDO, and hardware-configurable PWM mode, slew rate, OCP level, and current sense gain - all critical for automotive BLDC control designs.
Technical Context
The DRV8316CTQRGFRQ1 implements three independent half-bridge drivers with cycle-by-cycle overcurrent protection and active demagnetization logic to reduce power losses during freewheeling. Its hardware-configured interface uses four-level input pins (MODE, SLEW, GAIN, OCP/SR, VSEL_BK) to set PWM scheme, slew rate (14–280 V/µs), current sense gain (0.15–1.2 V/A), OCP threshold, and buck output voltage (3.3/4.0/4.6/5.7 V).
It integrates dual on-chip regulators: a 200-mA adjustable buck (3.3/4.0/4.6/5.7 V) and a 30-mA 3.3-V LDO, both powered from VM. Protection includes UVLO, CPUV, OTW/OTSD, and OCP, with fault status indicated via open-drain nFAULT and optional SPI diagnostics in the SPI variant - though DRV8316CTQRGFRQ1 uses pin-based configuration only.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Operating Voltage | 4.5 V to 35 V (40 V absolute max); supports 12-V automotive systems with headroom for load dump. |
| Peak Output Current | 8 A per phase; enables driving <40-W BLDC motors without external current amplification. |
| RDS(ON) (HS + LS) | 95 mΩ typ. at 25°C; minimizes conduction loss and thermal stress in compact layouts. |
| PWM Frequency Support | Up to 200 kHz; allows high-resolution sinusoidal or FOC control with reduced audible noise. |
| Sleep Current | 2.5 µA max at 13.5 V, 25°C; meets automotive low-power standby requirements. |
| Buck Regulator Output | Configurable 3.3 V / 4.0 V / 4.6 V / 5.7 V, 200 mA; powers MCU, sensors, or gate drivers without external DC/DC. |
| LDO Output | 3.3 V, 30 mA; supplies analog circuitry (e.g., current sense amps, reference circuits) with low noise. |
Pinout & Package
DRV8316CTQRGFRQ1 is housed in a 40-pin VQFN package (7.0 mm × 5.0 mm) with exposed thermal pad connected to AGND. Pin functions are hardware-configured via MODE, SLEW, GAIN, OCP/SR, and VSEL_BK - no SPI interface present.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| INHA, INHB, INHC | High-side gate control inputs | Direct PWM signals to drive high-side MOSFETs of phases A/B/C; TTL/CMOS compatible. |
| INLA, INLB, INLC | Low-side gate control inputs | Direct PWM signals to drive low-side MOSFETs; enable 6x or 3x PWM commutation schemes. |
| OUTA, OUTB, OUTC | Half-bridge power outputs | Each pair (e.g., OUTA pins 13/14) delivers phase current to motor windings; rated for 40-V abs max. |
| nFAULT | Fault indicator output | Open-drain signal pulled low on UVLO, OCP, OTSD, or CPUV; requires external pull-up (1.8–5.0 V). |
| nSLEEP | Driver sleep control | Logic-low entry into ultra-low-power mode (2.5 µA); 20–40 µs pulse resets faults without sleep. |
| DRVOFF | Power-stage disable | Logic-high forces all six MOSFETs OFF, placing outputs in high-impedance state for safe coasting. |
| GAIN, MODE, SLEW, OCP/SR, VSEL_BK | Hardware configuration inputs | Four-level resistor-divider inputs setting CSA gain, PWM mode, slew rate, OCP level, and buck voltage. |
| SOA, SOB, SOC | Current sense amplifier outputs | Analog outputs proportional to phase current (0.15–1.2 V/A); support RC filtering for noise immunity. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated current sensing | Eliminates need for external shunt resistors and associated PCB area, BOM cost, and thermal drift errors. |
| Active demagnetization | Reduces power dissipation during freewheeling by synchronously turning on low-side FETs, improving efficiency at high speeds. |
| Configurable slew rate (4 settings) | Enables EMI optimization: slower edges for noise-sensitive environments, faster edges for efficiency and resolution. |
| Dual integrated regulators | 3.3/4.0/4.6/5.7-V buck (200 mA) + 3.3-V LDO (30 mA) simplify power tree and reduce external component count. |
| Hardware-only configuration | No firmware or SPI bus required - ideal for safety-critical or cost-sensitive automotive modules with fixed functionality. |

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 |
|---|---|---|---|
| DRV8316CRQ1 | SPI-configurable variant (40-pin VQFN); supports register-level tuning of OCP retry, diagnostics, and SDO configuration. | Required when dynamic runtime reconfiguration or fault logging over SPI is needed - not supported by DRV8316CTQRGFRQ1's pin-strapped interface. | Select DRV8316CRQ1 if firmware-controlled adaptability or diagnostic traceability is essential; otherwise, DRV8316CTQRGFRQ1 offers simpler, robust hardware setup. |
| MP6532GQ-Z | Monolithic 3-phase driver with 6-A peak current, 120-mΩ RDS(ON), no integrated buck/LDO, and SPI-only configuration. | Lacks onboard regulators and hardware config; requires external 3.3-V supply and more external components for full system integration. | Choose MP6532GQ-Z only if lower BOM cost justifies added external power design complexity and reduced integration. |
Compared with DRV8316CRQ1, DRV8316CTQRGFRQ1 trades SPI flexibility for deterministic pin-based setup and eliminates communication overhead; versus MP6532GQ-Z, it delivers higher integration (buck + LDO + current sensing) and automotive-grade protection, but at higher pin count and fixed configuration.

FAQ
What is the maximum PWM frequency supported by the DRV8316CTQRGFRQ1?
The DRV8316CTQRGFRQ1 supports PWM frequencies up to 200 kHz. This enables high-resolution field-oriented control (FOC) and sinusoidal commutation for low acoustic noise and smooth motor operation in automotive BLDC applications such as fans and pumps. The device maintains stable gate drive and current sensing performance across this full range.
Does the DRV8316CTQRGFRQ1 require external current sense resistors?
No, the DRV8316CTQRGFRQ1 does not require external current sense resistors. It features integrated current sensing with three analog outputs (SOA, SOB, SOC) providing voltage signals proportional to phase current (0.15–1.2 V/A). This eliminates shunt resistor placement, layout sensitivity, and thermal drift, simplifying design and improving reliability.
How is configuration handled on the DRV8316CTQRGFRQ1 compared to the SPI variant?
The DRV8316CTQRGFRQ1 uses hardware pin-based configuration - not SPI. Settings for PWM mode, slew rate, current sense gain, OCP level, and buck voltage are determined by resistor-divider networks tied to MODE, SLEW, GAIN, OCP/SR, and VSEL_BK pins. This provides deterministic, firmware-free setup ideal for safety-critical or cost-optimized automotive modules.
What protection features are integrated into the DRV8316CTQRGFRQ1?
The DRV8316CTQRGFRQ1 integrates supply undervoltage lockout (UVLO), charge pump undervoltage (CPUV), overcurrent protection (OCP) with cycle-by-cycle limiting, thermal warning (OTW) and shutdown (OTSD), and fault indication via the open-drain nFAULT pin. These protections safeguard the IC, motor, and system without requiring external supervision circuitry.
What are the output voltage options for the integrated buck regulator in the DRV8316CTQRGFRQ1?
The integrated buck regulator in the DRV8316CTQRGFRQ1 offers four selectable output voltages: 3.3 V, 4.0 V, 4.6 V, or 5.7 V - configured by tying the VSEL_BK pin to AGND, Hi-Z, 47 kΩ to AVDD, or AVDD respectively. It delivers up to 200 mA and supports inductor- or resistor-based output stages for flexible system power architecture.
