Product details
Overview
DRV8824QPWPRQ1 from Texas Instruments is an AEC-Q100 Grade 1 automotive bipolar stepper motor driver IC with integrated microstepping indexer, dual NMOS H-bridge output stage, and programmable decay mode control. It delivers up to 1.6-A peak output current per winding at 24 V/25°C, supports 1/32 microstepping resolution, operates from 8.2 V to 45 V, and features built-in 3.3-V reference output - used in HVAC actuator positioning systems requiring precise motion control under extended temperature conditions.
For engineers reviewing the DRV8824QPWPRQ1 datasheet, DRV8824QPWPRQ1 pinout, DRV8824QPWPRQ1 application, or DRV8824QPWPRQ1 equivalent, key selection criteria include its automotive-grade thermal shutdown (150°C), configurable fast/slow/mixed decay modes, STEP/DIR interface simplicity, and HTSSOP-28 PowerPAD™ package with verified 1.6-A continuous drive capability at 125°C ambient.
Technical Context
The DRV8824QPWPRQ1 integrates two independent NMOS H-bridge drivers with matched RDS(ON) (0.63 Ω HS / 0.65 Ω LS typ. at 25°C), a fixed-frequency PWM current regulator using external sense resistors and internal 5× gain amplifiers, and a deterministic microstepping indexer with MODE0–MODE2-configurable step resolution (full to 1/32-step). Its charge-pump gate driver enables high-side NMOS operation across the full 8.2–45-V supply range.
Protection architecture includes independent analog overcurrent detection (1.8–5 A trip), undervoltage lockout (7.8–8.2 V), and thermal shutdown (150–180°C die temperature). The device uses a 3.75-μs current-sense blanking window and supports mixed-decay timing via DECAY pin logic state (low = slow, high = fast, open = mixed), enabling optimized torque ripple and power dissipation trade-offs in automotive valve control.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Current | 1.6-A peak per winding (with heatsinking at 24 V/25°C); enables driving NEMA17-class stepper motors in automotive HVAC actuators. |
| Supply Voltage | 8.2 V to 45 V operating range; supports direct connection to 12-V and 24-V vehicle battery rails with transient tolerance. |
| Microstepping | 1/32-step resolution via MODE0–MODE2 pins; provides 45° electrical angle resolution for smooth, low-vibration positioning. |
| RDS(ON) | 0.63 Ω (HS) / 0.65 Ω (LS) typical at 25°C; reduces conduction loss and junction temperature rise during continuous 1.1-A RMS operation. |
| Decay Modes | Programmable fast/slow/mixed decay via DECAY pin; allows dynamic optimization of back-EMF handling and current regulation accuracy. |
| Thermal Shutdown | 150°C nominal trigger point; disables outputs and asserts nFAULT to prevent permanent damage during overload or poor PCB heatsinking. |
| Reference Output | Built-in 3.3-V regulator (±3% accuracy, 1-mA load); supplies stable voltage for AVREF/BVREF without external LDO. |
Pinout & Package
DRV8824QPWPRQ1 is housed in a thermally enhanced HTSSOP-28 package (9.7 mm × 4.4 mm) with exposed PowerPAD™ for PCB-level heat dissipation. The package requires soldering the exposed pad to a minimum 20 cm² copper area connected via ≥6 thermal vias to internal ground planes for rated 1.6-A operation at 125°C ambient.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| GND (14, 28) | Power ground reference | Common return path for motor current, logic, and sense circuits; must be low-inductance connection to minimize noise coupling. |
| VMA (4), VMB (11) | Motor bridge power inputs | Parallel-connected terminals for 8.2–45-V supply; require local 0.47-μF ceramic bypass at each pin to suppress switching transients. |
| AOUT1/AOUT2 (5,7), BOUT1/BOUT2 (10,8) | H-bridge motor outputs | Drive bipolar stepper windings; polarity defines positive current direction (AOUT1→AOUT2, BOUT1→BOUT2). |
| ISENA (6), ISENB (9) | Current sense return nodes | Connect to low-side sense resistors; internal 5× amplifier converts sense voltage to match VREF scaling for accurate current regulation. |
| STEP (22), DIR (20) | Digital motion control interface | Rising-edge-triggered step clock and level-sensitive direction control; internal 100-kΩ pulldown ensures safe default state. |
| MODE0–MODE2 (24–26) | Microstep resolution select | Binary-encoded inputs selecting full, 1/2, 1/4, 1/8, 1/16, or 1/32 step; all internally pulled down for full-step default at power-up. |
| DECAY (19) | Decay mode control | Logic-low = slow decay, logic-high = fast decay, open = mixed decay; internal 130-kΩ pullup + 80-kΩ pulldown enables robust floating-state detection. |
| nFAULT (18), nHOME (27) | Open-drain status outputs | nFAULT = active-low fault indicator (overtemp/overcurrent/UVLO); nHOME = active-low home position flag aligned to step table index 0. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar stepper motor driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DRV8825PWP | Non-automotive grade (industrial), identical pinout and feature set but lacks AEC-Q100 qualification and Grade 1 temperature range. | Suitable for non-safety-critical consumer or industrial motion control where -40°C to +125°C operation is not required. | Select DRV8825PWP only if automotive qualification and extended temperature validation are unnecessary for the target application. |
| TMC2209-VQ | Integrated spreadCycle™ stealthChop, lower RDS(ON) (0.15 Ω), but requires SPI configuration and lacks built-in 3.3-V reference. | Better suited for ultra-quiet applications like premium audio equipment; requires additional MCU firmware overhead for setup. | Choose TMC2209-VQ when acoustic noise reduction is prioritized over design simplicity and automotive compliance. |
Compared with DRV8824QPWPRQ1, DRV8825PWP offers identical functionality without automotive qualification, while TMC2209-VQ delivers superior noise performance at the cost of increased software complexity and no integrated reference - making DRV8824QPWPRQ1 optimal for drop-in automotive stepper control where reliability and minimal BOM count are critical.

FAQ
What is the maximum continuous output current specification for DRV8824QPWPRQ1?
The DRV8824QPWPRQ1 supports up to 1.6-A peak output current per winding at 24 V and 25°C with adequate heatsinking. Continuous RMS current is approximately 1.1 A per winding, limited by thermal constraints and PCB copper area. Derating is required above 25°C ambient - at 125°C case temperature, maximum usable current drops to ~0.8 A RMS to maintain safe junction temperature.
Does DRV8824QPWPRQ1 require external current sense resistors?
Yes, DRV8824QPWPRQ1 requires external low-value sense resistors connected between ISENA/GND and ISENB/GND to implement closed-loop current regulation. The device uses internal 5× gain amplifiers to convert sense voltage to match the VREF input scale, enabling precise winding current control without external op-amps or ADCs.
How does the DECAY pin configure decay modes on DRV8824QPWPRQ1?
The DECAY pin on DRV8824QPWPRQ1 selects decay behavior: logic low enables slow decay (both low-side FETs active), logic high enables fast decay (H-bridge reverses polarity), and open/floating enables mixed decay (75% fast + 25% slow per PWM cycle). Internal 130-kΩ pullup and 80-kΩ pulldown resistors ensure stable mixed-decay default when unconnected.
What is the purpose of the nHOME output on DRV8824QPWPRQ1?
The nHOME output on DRV8824QPWPRQ1 is an open-drain signal that asserts low when the internal microstepping indexer reaches its defined home position (electrical angle 45°, corresponding to step table index 0). It is used for homing sequences in automotive actuators and resets automatically after nRESET assertion or power-on initialization.
Can DRV8824QPWPRQ1 operate from a 12-V automotive battery directly?
Yes, DRV8824QPWPRQ1 operates from 8.2 V to 45 V, making it compatible with nominal 12-V and 24-V vehicle battery systems. It includes undervoltage lockout (7.8–8.2 V) to disable outputs during cranking events, and its AEC-Q100 Grade 1 qualification ensures reliable function across the full -40°C to +125°C junction temperature range encountered in automotive environments.
