Product details
Overview
DRV8872DDA from Texas Instruments is a 3.6-A brushed DC motor driver IC in an 8-pin HSOP package with PowerPAD™, operating from 6.5 V to 45 V. It integrates an H-bridge of four N-channel MOSFETs (565 mΩ typical RDS(on)), PWM-controlled bidirectional motor drive, integrated current regulation via ISEN pin, and fault reporting via open-drain nFAULT. It is used in printer paper feed mechanisms requiring precise stall-current limiting and thermal-safe operation.
For engineers reviewing the DRV8872DDA datasheet, DRV8872DDA pinout, DRV8872DDA application, or DRV8872DDA equivalent, key selection criteria include its 3.6-A peak current capability, 6.5–45 V wide input range, integrated OCP/UVLO/TSD protection, sleep-mode current (10 µA), and compatibility with 0–200 kHz PWM control for speed and torque management.
Technical Context
The DRV8872DDA implements a fully integrated H-bridge using four N-channel MOSFETs with internal charge pump for high-side gate drive, enabling full enhancement across its 6.5–45 V VM range. Its current regulation uses a fixed 0.35 V (typ) VTRIP threshold on the ISEN pin to trigger slow-decay current chopping with 25 µs tOFF.
Protection logic includes VM undervoltage lockout (6.4 V nominal trip), overcurrent detection (4.5 A typical OCP threshold), and thermal shutdown at 150 °C with 40 °C hysteresis. Fault conditions pull nFAULT low and automatically recover when cleared - no external reset required.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 6.5 V to 45 V - supports 12 V, 24 V, and 36 V industrial and appliance power rails without external regulators. |
| Peak Output Current | 3.6 A - enables driving medium-torque DC motors (e.g., 24 V, 1.5 N·m) with short-duration stall capability. |
| RDS(on) (HS + LS) | 565 mΩ typical - limits conduction loss to ≤1.5 W at 2 A RMS, reducing heatsink requirements on FR-4 PCBs. |
| Current Regulation Threshold | 0.35 V (typ) on ISEN - sets motor current limit via external sense resistor (e.g., 0.16 Ω → 2.2 A trip). |
| Sleep Mode Current | 10 µA at 12 V - allows battery-powered devices (e.g., portable printers) to maintain multi-week standby life. |
| PWM Frequency Support | 0–200 kHz - supports high-frequency PWM (>20 kHz) to eliminate audible noise in consumer appliances. |
| nFAULT Output Type | Open-drain - simplifies interface to 1.8 V/3.3 V/5 V microcontrollers with single pull-up resistor. |
Pinout & Package
Package: 8-pin HSOP (DDA) with exposed thermal pad (4.9 mm × 6.0 mm); requires soldering thermal pad to multilayer ground plane with ≥6 vias for thermal performance (RθJB = 23.1 °C/W).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| GND (Pin 1) | Logic ground reference | Must connect to system digital ground; separate from high-current power ground unless star-point grounded. |
| IN2 (Pin 2) | H-bridge logic input | Controls bridge state per Table 1; internal 100 kΩ pulldown enables coast/sleep on power-up if left floating. |
| IN1 (Pin 3) | H-bridge logic input | Paired with IN2 to define forward/reverse/brake/coast; compatible with 3.3 V or 5 V logic levels. |
| nFAULT (Pin 4) | Fault status indicator | Open-drain output pulled low during UVLO/OCP/TSD; requires external pull-up (e.g., 10 kΩ to 3.3 V). |
| VM (Pin 5) | Main power supply | 6.5–45 V motor and IC supply; requires 0.1 µF ceramic + ≥47 µF bulk capacitor near pin. |
| OUT1 (Pin 6) | H-bridge output | Connects directly to one motor terminal; handles bidirectional current up to 3.6 A peak. |
| ISEN (Pin 7) | Current sense input | Accepts voltage drop across external sense resistor; 0.35 V threshold enables precise current limiting. |
| OUT2 (Pin 8) | H-bridge output | Connects to second motor terminal; complements OUT1 to complete H-bridge path. |
| Thermal Pad | Power dissipation path | Must be soldered to PCB ground plane; primary thermal conduction path (RθJC(bot) = 2.7 °C/W). |
Key Features
| Feature | Design Value |
|---|---|
| Integrated charge pump | Enables full enhancement of high-side N-FETs across entire 6.5–45 V VM range - no external bootstrap components needed. |
| Automatic fault recovery | Resumes normal operation within 3 ms after OCP or TSD fault removal - eliminates need for MCU watchdog or reset circuitry. |
| Programmable current regulation | Uses external sense resistor to set precise ITRIP; avoids overdesigning motor supply capacitance and reduces inrush stress during startup. |
| Low-power sleep mode | Enters <10 µA quiescent state when both IN1 and IN2 held low for 1 ms - critical for energy-constrained portable mechatronic systems. |
| Dead-time insertion | 220 ns automatic dead time prevents shoot-through during switching transitions - ensures robust operation without external timing control. |

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 | Lower 1.2 A peak current; 2.5–13.5 V supply; no integrated current regulation; dual H-bridge (2 motors) | Better suited for low-voltage dual-motor robotics; lacks fault reporting and wide-VM support | Select when driving two small 5–12 V motors and board space permits larger SOIC package. |
| DRV8876PWPR | Same 3.6 A rating and 6.5–45 V range; adds SPI interface and enhanced diagnostics; 16-pin HTSSOP package | Supports firmware-configurable current limits and fault logging; higher BOM cost and layout complexity | Select when system-level diagnostics, programmable trip points, or multi-device synchronization are required. |
Compared with TB6612FNG, DRV8872DDA delivers 3× higher peak current and operates across industrial 24/36 V rails, while DRV8876PWPR adds configurability at the cost of pin count and footprint - DRV8872DDA remains optimal for cost-sensitive, single-motor, wide-input applications needing analog current regulation and minimal external components.

FAQ
What is the maximum continuous output current supported by the DRV8872DDA?
The DRV8872DDA supports 3.5 A continuous output current (100% duty cycle) per Absolute Maximum Ratings, and 3.6 A peak current for short durations. Actual continuous current depends on PCB thermal design: with proper PowerPAD grounding and 2-layer FR-4, it sustains 2 A RMS at 25 °C ambient. Exceeding this without heatsinking risks thermal shutdown activation.
How does current regulation work on the DRV8872DDA, and what external component is required?
DRV8872DDA regulates motor current by comparing voltage on the ISEN pin to an internal 0.35 V (typ) reference. When the voltage across an external sense resistor exceeds this threshold, the device initiates slow-decay current chopping for 25 µs. A low-inductance surface-mount resistor (e.g., 0.16 Ω, 1 W) must be placed between ISEN and GND to set the trip point - DRV8872DDA itself contains no internal sense element.
Can the DRV8872DDA operate with a 5 V logic supply while powering a 36 V motor?
Yes. The DRV8872DDA accepts logic inputs (IN1/IN2) from 0 V to 5.5 V independent of VM, which can range from 6.5 V to 45 V. This allows direct interfacing with 3.3 V or 5 V microcontrollers while driving 24 V or 36 V brushed DC motors - no level shifters required. The internal charge pump ensures high-side FET enhancement across the full VM range.
What protection features are integrated into the DRV8872DDA, and how is fault status communicated?
The DRV8872DDA integrates VM undervoltage lockout (6.4 V trip), overcurrent protection (4.5 A typical OCP threshold), and thermal shutdown (150 °C). All faults pull the open-drain nFAULT pin low. Once the fault condition clears - e.g., VM recovers above 6.5 V or temperature drops below 110 °C - nFAULT returns high-impedance and the device resumes operation automatically without MCU intervention.
Is the DRV8872DDA pin-compatible with other TI motor drivers like the DRV8871 or DRV8876?
No. The DRV8872DDA (8-pin HSOP) has a unique pinout incompatible with DRV8871 (8-pin SOIC, no PowerPAD, different ISEN placement) and DRV8876 (16-pin HTSSOP, SPI interface). While functional similarities exist, PCB layout and schematic must be redesigned for substitution - DRV8872DDA's DDA package requires dedicated thermal pad routing not present in SOIC variants.
