Product details
Overview
DRV8832QDGQRQ1 from Texas Instruments is an AEC-Q100 Grade 1 qualified brushed DC motor driver IC with integrated H-bridge, PWM voltage regulation, and current limiting. It delivers up to 1-A continuous/1.3-A peak output current, operates from 2.75 V to 6.8 V, and features a 450 mΩ (HS+LS) total RDS(on), 300-nA sleep current, and fault reporting via open-drain FAULTn pin - used in battery-powered automotive cabin actuators and portable robotics.
For engineers reviewing the DRV8832QDGQRQ1 datasheet, DRV8832QDGQRQ1 pinout, DRV8832QDGQRQ1 application, or DRV8832QDGQRQ1 equivalent, key selection criteria include its regulated voltage control architecture, external current-sense resistor programmability, thermal shutdown behavior, and compatibility with low-voltage Li-ion or alkaline battery systems requiring stable motor speed under supply variation.
Technical Context
The DRV8832QDGQRQ1 implements a closed-loop PWM voltage regulator that compares a divided motor output voltage (÷4) against the externally set VSET reference to dynamically adjust duty cycle - enabling constant motor speed across 2.75–6.8 V supply range. Its H-bridge uses complementary N/P-channel MOSFETs with independent overcurrent protection on each FET leg.
Control logic interprets IN1/IN2 states for forward, reverse, brake, and sleep modes; sleep mode disables outputs and reduces quiescent current to 300 nA typical. Fault conditions - including UVLO (2.75 V threshold), OCP (>1.3 A trip), and TSD (>150 °C) - assert FAULTn low and disable the bridge until cleared by power cycle or condition removal.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.75 V to 6.8 V - supports single-cell Li-ion (3.0–4.2 V), dual alkaline (3.0–3.6 V), and 5-V rail systems without external regulators. |
| Continuous Output Current | 1 A - sustained drive capability for small DC motors (e.g., <10 W) with adequate PCB heatsinking (RθJA = 69.3 °C/W). |
| Peak Output Current | 1.3 A - handles motor startup/stall surges before current-limit deglitch timeout (275 ms). |
| Total RDS(on) | 450 mΩ max (HS + LS @ 125°C) - limits conduction loss to ≤0.45 W at 1-A load, enabling >85% efficiency at mid-load. |
| Sleep Mode Current | 300 nA typical - enables multi-year battery life in intermittently active devices like smart locks or sensor actuators. |
| Voltage Regulation Accuracy | ±1% line/load regulation - maintains programmed motor voltage within tight tolerance despite battery discharge or load transients. |
| Fault Reporting | Open-drain FAULTn - signals UVLO, OCP, or TSD to host MCU without level-shifting; requires external pull-up. |
Pinout & Package
DRV8832QDGQRQ1 is housed in a thermally enhanced 10-pin MSOP-PowerPAD package (3.0 mm × 3.0 mm) with exposed thermal pad (GND-connected) for improved heat dissipation in space-constrained automotive and portable designs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| OUT2 (Pin 1) | H-bridge low-side output | Connects directly to one motor terminal; sinks current during forward/reverse operation. |
| ISENSE (Pin 2) | Current sense input | Monitors voltage drop across external sense resistor (0–1 Ω) to enable programmable current limiting (trip at 200 mV). |
| OUT1 (Pin 3) | H-bridge high-side output | Connects directly to opposite motor terminal; sources current during forward/reverse operation. |
| VCC (Pin 4) | Power supply input | Supplies both logic and motor drive circuitry; requires ≥0.1-μF ceramic bypass capacitor to GND. |
| GND (Pin 5) | Ground reference | Primary signal and power ground; PowerPAD (pin 5) must be soldered to large copper pour for thermal performance. |
| FAULTn (Pin 6) | Open-drain fault indicator | Drives low during UVLO, OCP, or TSD; requires external pull-up resistor to host logic rail. |
| VSET (Pin 7) | Voltage regulation setpoint | Accepts 0–1.335 V input; sets regulated motor voltage as VMOTOR = 4 × VVSET (e.g., 0.75 V → 3.0 V). |
| VREF (Pin 8) | Internal reference output | Provides stable 1.285 V ±50 mV reference for generating precise VSET via resistor divider. |
| IN1 (Pin 9) | H-bridge control input | Logic-level input (0.25×VCC low / 0.5×VCC high) controlling OUT1 state per truth table (forward/brake/sleep). |
| IN2 (Pin 10) | H-bridge control input | Logic-level input (0.25×VCC low / 0.5×VCC high) controlling OUT2 state; paired with IN1 to define motor direction and mode. |

FAQ
What is the maximum continuous output current rating for the DRV8832QDGQRQ1?
The DRV8832QDGQRQ1 is rated for 1-A continuous (DC/RMS) output current under proper thermal conditions - specifically with sufficient PCB copper area connected to the PowerPAD for heatsinking. This rating assumes ambient temperature ≤85°C and junction temperature ≤125°C. At higher ambient or with limited copper, derating applies per the thermal metrics (RθJA = 69.3 °C/W). Peak current capability is 1.3 A, intended for short-duration events like motor startup.
How does the voltage regulation function work in the DRV8832QDGQRQ1?
The DRV8832QDGQRQ1 implements an internal PWM-based voltage regulator that maintains constant motor voltage despite supply variation. It samples the motor output voltage, divides it by 4, and compares it to the external VSET voltage. If the divided value is lower than VSET, the PWM duty cycle increases; if higher, it decreases. The regulated motor voltage equals 4 × VSET (e.g., 0.75 V on VSET yields 3.0 V across the motor). This loop operates autonomously without MCU involvement.
Can the DRV8832QDGQRQ1 be used without the voltage regulation feature?
Yes - the DRV8832QDGQRQ1 functions as a standard H-bridge when voltage regulation is disabled. This occurs when the desired motor voltage exceeds the supply voltage (VMOTOR > VCC), forcing 100% PWM duty cycle. In this mode, motor speed is controlled solely by IN1/IN2 logic states (forward/reverse/brake/sleep), and VSET may be left unconnected or tied to GND. All protection features (OCP, UVLO, TSD) remain fully active.
What is the purpose of the ISENSE pin on the DRV8832QDGQRQ1?
ISENSE is the current sense input pin that monitors voltage across an external sense resistor placed between the motor winding and GND. When the sensed voltage exceeds 200 mV for >3 µs, the DRV8832QDGQRQ1 reduces PWM duty cycle to limit motor current. The resistor value (0–1 Ω) sets the current limit threshold: RSENSE = 0.2 V / ILIMIT. For example, a 0.22 Ω resistor configures a 0.9-A limit. If current limiting is unused, ISENSE may be connected directly to GND.
Does the DRV8832QDGQRQ1 require external components for basic operation?
Yes - minimal external components are required: a 0.1-μF ceramic capacitor from VCC to GND for power supply decoupling; an external current-sense resistor (0–1 Ω) connected between ISENSE and GND for current limiting; and a pull-up resistor on FAULTn for fault indication. Optional components include a resistor divider from VREF to VSET for precise voltage regulation, and bulk capacitance near the motor terminals to suppress switching noise and supply ripple.
