Texas Instruments DRV8830DGQR

Overview

DRV8830DGQR from Texas Instruments is a low-voltage, I²C-controlled brushed DC motor driver IC with integrated H-bridge, PWM voltage regulation, and current limiting. It delivers up to 1.3-A peak output, operates from 2.75 V to 6.8 V, and maintains constant motor speed across battery discharge cycles in portable printers and robotic actuators.

For engineers reviewing the DRV8830DGQR datasheet, DRV8830DGQR pinout, DRV8830DGQR application, or DRV8830DGQR equivalent, key selection criteria include its 10-pin HVSSOP package, I²C address configurability (up to 9 devices), 450-mΩ total R_DS(on), fault reporting via open-drain FAULTn, and programmable 0.48 V–5.06 V regulated output voltage.

Technical Context

The DRV8830DGQR implements a closed-loop PWM voltage regulation architecture using an internal 1.285-V reference and 6-bit DAC to set motor winding voltage. It continuously monitors the average output voltage (divided by 4) and adjusts duty cycle to maintain commanded V_SET, enabling stable speed control under varying supply conditions.

Its protection system includes independent high-side/low-side overcurrent detection (1.3-A trip), thermal shutdown at 150°C, undervoltage lockout at 2.47 V (falling), and fault reporting via both FAULTn pin and serial register bits-enabling robust operation in battery-powered motion systems without external supervision.

FAQ

What is the maximum continuous output current supported by the DRV8830DGQR?

The DRV8830DGQR supports up to 1-A continuous (DC/RMS) output current when sufficient PCB heatsinking is provided, as specified in the Recommended Operating Conditions table. Its 1.3-A peak rating applies to short-duration transients such as motor startup. Thermal performance depends on board layout, copper area, and ambient temperature-R_θJB is 9.5 °C/W for the HVSSOP package with PowerPAD™.

How does the DRV8830DGQR achieve constant motor speed across varying battery voltage?

The DRV8830DGQR uses an internal PWM voltage regulation loop that compares the averaged motor winding voltage (divided by 4) against a DAC-set reference (V_SET). When battery voltage drops, the device automatically increases PWM duty cycle to maintain the programmed output voltage-ensuring consistent motor speed without external feedback or MCU intervention. This is implemented entirely within the DRV8830DGQR.

Can multiple DRV8830DGQR devices share the same I²C bus?

Yes-up to 9 DRV8830DGQR devices can operate on a single I²C bus. Each device's 7-bit slave address is determined by strapping A0 and A1 pins to GND, VCC, or leaving them open, yielding 9 unique base addresses (0xC0–0xD0). The upper 4 address bits are fixed; no software address reconfiguration is required after power-up.

What protection features are integrated into the DRV8830DGQR?

The DRV8830DGQR integrates four independent protection mechanisms: undervoltage lockout (UVLO) below 2.47 V, overtemperature shutdown at 150°C, analog overcurrent protection (OCP) at 1.3-A per FET, and a 275-ms-deglitched current limit fault (ILIMIT) triggered at 200 mV across the ISENSE resistor. All faults assert the open-drain FAULTn pin and set corresponding bits in the serial FAULT register.

Is the DRV8830DGQR pin-compatible with other packages of the same part number?

No-the DRV8830DGQR designation specifically refers to the 10-pin HVSSOP package with PowerPAD™. While the DRV8830 family also offers a VSON (DRC) variant, the DGQR suffix denotes the HVSSOP (DGQ) package only. Pinout is identical between DGQ and DRC packages, but thermal and mounting characteristics differ; PCB layout must match the selected package's footprint and thermal pad requirements.
