Product details
Overview
DRV8885PWPR from Texas Instruments is a PWM microstepping stepper motor driver IC with integrated current sense, dual N-channel H-bridge outputs, and STEP/DIR interface. It delivers 1.5-A full-scale / 1.0-A RMS output per bridge across an 8–37-V supply, supports up to 1/16 microstepping, and operates in industrial motion control systems such as 3D printers and video security cameras.
For engineers reviewing the DRV8885PWPR datasheet, DRV8885PWPR pinout, DRV8885PWPR application, or DRV8885PWPR equivalent, this page provides verified technical context, validated pin functions for the 24-pin HTSSOP package, confirmed current regulation accuracy (±6.25%), decay mode flexibility (slow/mixed), and real-world thermal performance data at 25°C and 125°C ambient.
Technical Context
The DRV8885PWPR integrates a microstepping indexer with configurable M0/M1 inputs for full-step through 1/16-step modes-including non-circular 1/2-step for higher torque-and uses adaptive blanking time scaling to minimize zero-crossing distortion at low-current steps. Its fixed off-time PWM chopping employs RREF-based current regulation with ±6.25% full-scale accuracy over 71–100% current settings.
Protection architecture includes VM undervoltage lockout (7.8 V trip), charge pump UVLO (VM + 2.0 V), overcurrent detection (2.3-A peak per FET), and thermal shutdown (150°C junction) with 20°C hysteresis. Fault status is reported via open-drain nFAULT with external pullup, while nSLEEP enables 20-μA quiescent sleep mode.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Current | 1.5-A full-scale / 1.0-A RMS per bridge - defines maximum continuous sinusoidal amplitude and thermal steady-state capability at 24 V, 25°C with proper PCB ground plane |
| Supply Voltage Range | 8–37 V - supports wide-input industrial motor supplies; UVLO triggers at 7.8 V falling, recovers at 8.0 V rising |
| Microstepping Resolution | Up to 1/16 step - selectable via M0/M1 pins; includes non-circular 1/2-step mode for improved high-RPM torque |
| RDS(ON) | 0.86 Ω total (HS + LS) at 24 V, 25°C - determines conduction loss and thermal rise under load; varies with temperature and voltage |
| Current Sense Accuracy | ±6.25% full-scale - achieved without external sense resistors; applies to 71–100% current range with 1% RREF resistor |
| Decay Modes | Slow, mixed, slow/mixed - configured via DECAY pin; slow/mixed uses slow decay on increasing steps and mixed on decreasing steps |
| Sleep Current | 20 μA at 25°C - enables ultra-low-power standby; rises to 40 μA at 125°C ambient |
Pinout & Package
DRV8885PWPR is packaged in a 24-pin HTSSOP PowerPAD™ (7.80 mm × 4.40 mm) with exposed thermal pad for enhanced heat dissipation. Pin numbering follows standard top-view orientation with thermal pad connected to PGND.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| AOUT1, AOUT2 | Winding A H-bridge outputs | Drive one phase of bipolar stepper motor; rated for 2.3-A peak, require low-inductance PCB routing |
| BOUT1, BOUT2 | Winding B H-bridge outputs | Drive second phase; complementary to AOUT pair; share same current rating and thermal limits |
| STEP, DIR | Digital control inputs | STEP rising edge advances indexer state; DIR logic level sets rotation direction; both have internal pulldowns |
| M0, M1 | Tri-level microstep mode select | Configure step resolution (full, 1/2, 1/4, 1/8, 1/16, non-circular 1/2); Hi-Z state enables 1/8 or non-circular 1/2 |
| RREF | Analog current limit reference | Resistor-to-ground sets full-scale current; transimpedance gain = 30 kΩ·A; voltage = 1.232 V typical |
| nFAULT | Open-drain fault indicator | Pulled low during UVLO, OCP, TSD, or CPUV; requires external pullup to DVDD or VCC (≥4.7 kΩ) |
| nSLEEP | Low-power enable control | Logic low enters 20-μA sleep mode; wake-up time = 0.85–1.5 ms; internal pulldown ensures safe default |
| VM, PGND, GND | Power supply terminals | VM (8–37 V) powers H-bridges; PGND handles high-current return; GND is logic ground - must be joined at single point |
Key Features
| Feature | Design Value |
|---|---|
| Integrated current sense | Eliminates two external high-power sense resistors; reduces board area, BOM cost, and power loss by avoiding resistor-based sensing |
| Adaptive blanking time | Scales minimum drive time with output current to suppress zero-crossing distortion in low-current microsteps |
| Torque DAC (TRQ pin) | Tri-level input scales output current digitally without changing RREF; enables dynamic power reduction during idle or low-load conditions |
| Thermal-aware protection | Combines junction temperature monitoring (150°C shutdown), RDS(ON)-based overcurrent detection (2.3-A peak), and thermal hysteresis (20°C) for robust operation |
| Flexible decay control | DECAY pin selects slow, mixed, or slow/mixed decay; slow/mixed optimizes torque consistency across bidirectional stepping |
Applications
| Multi-function Printers & Scanners | 3D Printers |

Equivalent & Alternatives
The following parts are listed as comparable options for similar stepper motor driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TB6600HG | Higher 4.5-A peak current but no integrated current sense; requires external 0.1-Ω sense resistors and separate indexer logic | Preferred for high-torque industrial actuators where board space allows discrete sensing and control | Select TB6600HG when >2.3-A peak current is required and system MCU can manage microstepping timing |
| LV8729V | Lower 1.2-A RMS rating; uses external sense resistors; supports only up to 1/8 microstepping and lacks TRQ torque scaling pin | Suitable for cost-sensitive consumer devices with lower thermal budgets and simpler motion profiles | Choose LV8729V for battery-powered portable scanners where 1.0-A RMS margin is excessive and footprint is critical |
Compared with TB6600HG and LV8729V, the DRV8885PWPR uniquely combines integrated current sense, 1/16 microstepping, torque DAC, and adaptive blanking in a single 24-pin HTSSOP - reducing component count, layout complexity, and firmware overhead for mid-power industrial motion systems.

FAQ
What is the maximum microstepping resolution supported by the DRV8885PWPR?
The DRV8885PWPR supports up to 1/16 microstepping, selectable via M0 and M1 pins. It also offers a non-circular 1/2-step mode for improved torque at higher motor speeds. The indexer executes all modes internally, eliminating the need for external waveform generation by the host controller. This capability is fully implemented in the DRV8885PWPR and confirmed in its datasheet revision D.
Does the DRV8885PWPR require external current sense resistors?
No, the DRV8885PWPR features integrated current sense functionality that eliminates the need for external high-power sense resistors. Current regulation is achieved using an internal transimpedance amplifier referenced to the RREF pin, delivering ±6.25% full-scale accuracy. This design reduces board area, BOM cost, and power loss - a core feature of the DRV8885PWPR as documented in TI's SLVSD39D datasheet.
What protection features are built into the DRV8885PWPR?
The DRV8885PWPR includes VM undervoltage lockout (7.8 V trip), charge pump undervoltage detection, overcurrent protection (2.3-A peak per FET), thermal shutdown (150°C junction), and fault reporting via the open-drain nFAULT pin. All protections are hardware-based and active during normal operation. These safeguards are integral to the DRV8885PWPR's architecture and validated across temperature and supply ranges.
How does the TRQ pin function on the DRV8885PWPR?
The TRQ pin on the DRV8885PWPR is a tri-level input that digitally scales output current without modifying the RREF resistor value. Logic low, Hi-Z, and logic high states correspond to 0%, ~71%, and 100% of full-scale current respectively. This torque DAC feature enables dynamic current adjustment - for example, reducing motor hold current during idle - and is a defined function of the DRV8885PWPR per its pin description table.
What is the thermal performance of the DRV8885PWPR in the HTSSOP package?
In the 24-pin HTSSOP PowerPAD™ package, the DRV8885PWPR has a junction-to-ambient thermal resistance (RθJA) of 36.1°C/W and a junction-to-board resistance (RθJB) of 15.8°C/W. With proper PCB copper pour on the thermal pad, it sustains 1.0-A RMS output continuously at 25°C ambient. Derating is required above 25°C - e.g., ~0.8-A RMS at 85°C ambient - as specified in the DRV8885PWPR's thermal characteristics table.
