Product details
Overview
DRV8832DRCT from Texas Instruments is a single H-bridge brushed DC motor driver IC designed for low-voltage battery-powered motion control. It delivers up to 1 A continuous/1.3 A peak output current, operates from 2.75 V to 6.8 V, integrates PWM voltage regulation and current limiting, and targets compact applications like portable printers and robotic actuators.
For engineers reviewing the DRV8832DRCT datasheet, DRV8832DRCT pinout, DRV8832DRCT application, or DRV8832DRCT equivalent, key selection considerations include its 10-pin VSON (3 mm × 3 mm) package, integrated voltage regulation via VSET/VREF, fault reporting on FAULTn, and thermal protection with automatic recovery - all critical for reliable low-power motor control in space-constrained designs.
Technical Context
The DRV8832DRCT implements a closed-loop PWM voltage regulation architecture that maintains constant motor speed across varying supply voltages by comparing a divided motor output voltage (÷4) against an externally set VSET reference. Its H-bridge uses complementary N-channel and P-channel MOSFETs with typical combined RDS(ON) of 450 mΩ at 85°C.
Current limiting is achieved via external sense resistor (ISENSE) monitoring with 200 mV threshold and 275 ms deglitch time before FAULTn assertion; overcurrent protection (OCP) and thermal shutdown (TSD) operate independently with hard disable and auto-recovery behavior. Sleep mode draws only 300 nA when both IN1 and IN2 are low.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.75 V to 6.8 V - supports single-cell Li-ion, NiMH, and alkaline battery systems without external regulators. |
| Continuous Output Current | 1 A - achievable with sufficient PCB heatsinking (RθJB = 18.8 °C/W in VSON package). |
| Peak Output Current | 1.3 A - enables short-duration motor start-up or stall current handling before current limit engages. |
| H-Bridge RDS(ON) | 450 mΩ (HS + LS, typ.) - minimizes conduction loss and self-heating during sustained operation. |
| Sleep Mode Current | 300 nA (typ.) - extends battery life in intermittent-use devices like remote-controlled toys. |
| Fault Reporting | Open-drain FAULTn - signals UVLO, OCP, or TSD events to host MCU with active-low assertion. |
| Voltage Regulation Accuracy | ±1% line/load regulation - ensures stable motor speed despite battery discharge or load variation. |
Pinout & Package
DRV8832DRCT is housed in a thermally enhanced 10-pin VSON package (3.00 mm × 3.00 mm) with exposed thermal pad (PPAD) on bottom for efficient heat dissipation into PCB copper.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN1 / IN2 | H-bridge logic inputs | Digital control signals defining forward, reverse, brake, or sleep mode per truth table; no internal pull-ups. |
| OUT1 / OUT2 | H-bridge motor outputs | Drive brushed DC motor winding; support recirculation via high-side FETs during PWM off-time. |
| VCC | Power supply input | Supplies both logic and motor power; requires 0.1 μF ceramic bypass capacitor placed adjacent to pin. |
| GND | Ground reference | Common return for power, logic, and current sense; connected to PPAD for thermal and electrical integrity. |
| ISENSE | Current sense input | Monitors voltage drop across external sense resistor (0–1 Ω); sets current limit trip at 200 mV. |
| VSET | Voltage regulation setpoint | Analog input setting regulated motor voltage (VMOTOR = 4 × VVSET); referenced to VREF. |
| VREF | Internal reference output | 1.285 V ±50 mV precision reference used to generate VSET via resistor divider for constant-speed control. |
| FAULTn | Open-drain fault indicator | Asserted low during UVLO, OCP, or TSD; requires external pull-up; pulses low on sleep-mode exit. |
Key Features
| Feature | Design Value |
|---|---|
| PWM voltage regulation | Maintains constant motor speed over varying battery voltage (e.g., 4.5 V → 5.5 V) without external feedback loop. |
| Integrated current limit | Configurable trip level (via ISENSE resistor) protects motor and IC during stall/start-up; self-clearing after fault removal. |
| Thermal shutdown with auto-recovery | Disables H-bridge at 150–180 °C die temperature and resumes operation once junction cools below hysteresis threshold. |
| Ultra-low sleep current | 300 nA typical draw eliminates need for external power switches in battery-critical applications like handheld cameras. |
| Robust protection suite | Independent UVLO, OCP, and TSD with distinct fault signaling - prevents latch-up and enables safe system-level error handling. |

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 | Higher 1.2 A continuous rating, dual H-bridge, 2.7–10 V supply, but lacks integrated voltage regulation and reference output. | Better suited for dual-motor systems or higher-voltage battery packs; requires external voltage control loop for constant speed. | Select when needing dual independent bridges or wider supply range; avoid if VSET-based regulation is required. |
| DRV8833C | Pin-compatible upgrade with identical VSON-10 package, 1.5 A peak, improved thermal resistance (RθJB = 14.9 °C/W), and same feature set. | Direct replacement offering higher current capability and better thermal performance without layout changes. | Prefer for new designs requiring margin on peak current or thermal headroom; retains full DRV8832DRCT software and control logic. |
Compared with TB6612FNG, DRV8832DRCT provides integrated voltage regulation and lower quiescent current but lower peak current; compared with DRV8833C, it offers identical functionality at reduced peak rating and thermal performance - making DRV8832DRCT optimal for cost-sensitive, space-constrained, single-motor applications where 1.3 A peak suffices.

FAQ
What is the maximum continuous output current supported by the DRV8832DRCT?
The DRV8832DRCT supports 1 A continuous (DC/RMS) output current when adequate PCB heatsinking is provided - verified by thermal data showing RθJB = 18.8 °C/W in the VSON package. This rating assumes ambient temperature ≤85°C and proper copper pour under the exposed pad. Exceeding 1 A continuously risks thermal shutdown unless board-level cooling is enhanced.
How does the DRV8832DRCT achieve constant motor speed across varying battery voltage?
The DRV8832DRCT uses an internal PWM voltage regulation loop that compares a quarter of the motor output voltage (measured across OUT1–OUT2) to the VSET input. When VCC drops (e.g., battery discharges), the duty cycle increases to maintain the programmed motor voltage - ensuring constant speed without external microcontroller intervention. The VREF pin (1.285 V) simplifies VSET generation via resistor divider.
What protection features are integrated into the DRV8832DRCT?
The DRV8832DRCT integrates undervoltage lockout (UVLO), overcurrent protection (OCP), and thermal shutdown (TSD). UVLO disables operation below 2.47–2.75 V; OCP triggers at >1.3 A and fully disables the H-bridge; TSD activates at 150–180 °C and auto-recovers upon cooling. All faults assert the open-drain FAULTn pin, enabling host MCU monitoring.
Can the DRV8832DRCT drive a stepper motor?
Yes - the DRV8832DRCT can drive one winding of a bipolar stepper motor (e.g., in half-step or wave-drive mode) using its single H-bridge. It is not suitable for full 2-phase bipolar control, but works effectively for unipolar steppers or partial-stepper applications where only one coil needs bidirectional current. External logic must sequence IN1/IN2 to achieve stepping patterns.
What is the purpose of the ISENSE pin on the DRV8832DRCT?
The ISENSE pin on the DRV8832DRCT connects to one end of an external current-sense resistor (0–1 Ω) placed between the motor winding and ground. It monitors voltage drop across this resistor to implement programmable current limiting: when the sensed voltage exceeds 200 mV, the device reduces PWM duty cycle to cap motor current. This protects against stall conditions and controls inrush during startup.
