Product details
Overview
DRV8830DGQ from Texas Instruments is a low-voltage, I²C-controlled brushed DC motor driver IC with integrated H-bridge, 1.3-A peak output current, 2.75 V to 6.8 V operating supply range, and programmable PWM voltage regulation for constant-speed motor control in battery-powered systems.
For engineers reviewing the DRV8830DGQ datasheet, DRV8830DGQ pinout, DRV8830DGQ application, or DRV8830DGQ equivalent, this page delivers verified technical context on serial interface configuration, thermal protection behavior, current-limiting implementation via external sense resistor, and functional mode transitions between forward/reverse/brake/standby.
Technical Context
The DRV8830DGQ integrates an N-channel/P-channel H-bridge with internal PWM voltage regulation using a 1.285-V reference DAC and 4× output scaling. It supports I²C communication at up to 400 kHz with nine configurable slave addresses via A0/A1 pins and implements fault reporting through open-drain FAULTn and register-mapped status bits.
Protection includes analog overcurrent detection (1.3-A trip), thermal shutdown (150–180°C), undervoltage lockout (2.47–2.575 V), and independent high-side/low-side FET current limiting. Current limit is set by external ISENSE resistor with 200-mV threshold and 275-ms deglitch timing before FAULTn assertion.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.75 V to 6.8 V - Enables direct operation from single-cell Li-ion (3.0–4.2 V) or two-cell alkaline (2.4–3.2 V) without LDO pre-regulation. |
| Peak Output Current | 1.3 A - Supports brief stall/startup surges of small DC motors while maintaining safe junction temperature under PCB heatsinking. |
| H-Bridge RDS(on) | 450 mΩ (HS+LS, typ.) - Limits conduction loss to ≤293 mW at 1-A RMS, enabling >85% efficiency at mid-load per typical curves. |
| I²C Interface Speed | Up to 400 kHz - Allows rapid reconfiguration of VSET, IN1/IN2 states, and fault clearing without MCU polling overhead. |
| Sleep Current | 300 nA (typ.) - Reduces quiescent drain in battery-critical standby modes, extending shelf life in remote or intermittent-use devices. |
| Fault Reporting | Dedicated FAULTn pin + FAULT register - Provides immediate hardware interrupt and software-readable root-cause identification (OCP/UVLO/OTS/ILIMIT). |
| Voltage Regulation Accuracy | ±1% line/load regulation - Maintains programmed motor voltage within ±30 mV across supply and load variations, ensuring stable speed control. |
Pinout & Package
DRV8830DGQ uses the 10-pin HVSSOP (DGQ) package with PowerPAD™ thermal pad (3.00 mm × 3.00 mm body). The exposed thermal pad must be soldered to PCB ground plane for RθJB = 51.6°C/W performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| OUT1 / OUT2 | H-bridge motor outputs | Drive brushed DC motor winding bidirectionally; support brake (both high), reverse (OUT1 low, OUT2 high), forward (OUT1 high, OUT2 low), or coast (both high-Z). |
| VCC | Motor and logic supply | Single 2.75–6.8 V rail powers both bridge FETs and internal logic; requires ≥0.1-μF ceramic bypass capacitor to GND. |
| GND | Power and signal reference | Common return for motor current, logic, and thermal pad; must connect to low-impedance ground plane for thermal and EMI control. |
| ISENSE | Current limit sense input | Connects to external resistor (0–1 Ω) between OUTx and GND; 200-mV threshold triggers current limiting and fault reporting. |
| SCL / SDA | I²C serial interface | Standard-mode (100 kHz) or fast-mode (400 kHz) bus lines; require external pull-up resistors to VCC. |
| A0 / A1 | I²C address select inputs | Set lower 2 bits of 7-bit slave address (0xC0–0xD0); latched at power-up - not dynamically changeable. |
| FAULTn | Open-drain fault indicator | Active-low signal asserts when UVLO/OCP/OTS/ILIMIT occurs; requires external pull-up to host MCU I/O or interrupt line. |
Key Features
| Feature | Design Value |
|---|---|
| Programmable PWM voltage regulation | 64-step DAC (0x00–0x3F) sets regulated motor voltage from 0.48 V to 5.06 V in 80-mV increments - enables precise speed control across battery discharge curve. |
| Configurable I²C addressing | 9 unique slave addresses via A0/A1 (GND/VCC/open) - allows daisy-chaining multiple DRV8830DGQ units on one bus for multi-motor systems. |
| Integrated overcurrent protection | Analog OCP circuit disables bridge within microseconds if current exceeds 1.3 A - protects against short circuits and mechanical stalls independent of software-based current limit. |
| Thermal shutdown with auto-recovery | Triggers at 150–180°C die temperature; resumes operation automatically after cooling below hysteresis threshold - avoids system lockup during transient overload. |
| Low-power sleep mode | 300-nA quiescent current when IN1=IN2=0 - ideal for intermittently active actuators in portable medical or IoT edge devices. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar brushed DC motor driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TB6612FNG | Two-channel H-bridge, 1.2-A continuous, TTL-level parallel interface, no integrated voltage regulation or I²C. | Requires external MCU PWM generation and voltage feedback loop for speed stability; better suited for dual-motor systems. | Select when needing dual independent drivers or simpler control interface; avoid if battery voltage compensation is required. |
| DRV8876N | Single-channel, 3.6-A peak, SPI interface, integrated current sensing (no external resistor), higher VCC range (4.5–45 V). | Targets higher-power industrial actuators; lacks I²C compatibility and low-voltage operation below 4.5 V. | Select for >3-A loads or SPI-based architectures; unsuitable for sub-3-V battery systems or I²C bus integration. |
Compared with TB6612FNG and DRV8876N, the DRV8830DGQ uniquely combines I²C configurability, sub-3-V operation, and closed-loop voltage regulation in a 10-pin HVSSOP - making it optimal for space-constrained, single-motor, battery-life-sensitive designs where speed consistency matters more than raw current capability.

FAQ
What is the maximum continuous output current rating for the DRV8830DGQ?
The DRV8830DGQ supports 1-A maximum DC/RMS output current when sufficient PCB heatsinking is provided, as specified in Recommended Operating Conditions. Peak current capability is 1.3 A, but sustained operation above 1 A requires careful thermal design per RθJA = 69.3°C/W (HVSSOP) and derating curves in the datasheet. Exceeding 1-A continuous risks thermal shutdown.
How does the DRV8830DGQ implement voltage regulation without an external feedback loop?
The DRV8830DGQ uses an internal 1.285-V reference and 6-bit DAC to generate a VSET voltage, which is compared against a scaled (÷4) version of the average motor voltage sensed across OUT1–OUT2. Its integrated PWM controller adjusts duty cycle autonomously to maintain the programmed output voltage - eliminating need for external op-amps, ADCs, or MCU-based PID loops.
Can the DRV8830DGQ operate from a 2.4-V supply?
No. The DRV8830DGQ has a minimum recommended operating supply voltage of 2.75 V, with undervoltage lockout (UVLO) activating below 2.47 V (falling) or 2.575 V (rising). Operation at 2.4 V will cause immediate UVLO shutdown and FAULTn assertion; it is not rated for reliable function below 2.75 V.
What happens to the motor when the DRV8830DGQ enters thermal shutdown?
When die temperature exceeds 150–180°C, the DRV8830DGQ disables all H-bridge FETs, drives FAULTn low, and sets the OTS bit in the FAULT register. Motor stops immediately. Once junction temperature falls below the hysteresis threshold (typically ~15°C below trip point), the device automatically resumes operation without reset - preserving system state and avoiding manual intervention.
Is the DRV8830DGQ pin-compatible with other packages in the DRV8830 family?
Yes. The DRV8830DGQ (HVSSOP-10) shares identical pinout, function mapping, and electrical specifications with the DRV8830DRC (VSON-10). Both packages use the same 10-pin layout, PowerPAD™ thermal pad, and pin assignments - allowing direct PCB footprint interchangeability where thermal and mechanical constraints permit.
