Product details

Overview

DRV8881PRHRR from Texas Instruments is a 28-pin WQFN-packaged dual H-bridge motor driver IC for bipolar stepper and brushed-DC motors, operating from 6.5 V to 45 V, delivering up to 2.5-A peak/1.4-A rms per bridge, with PWM control interface, parallel mode support, and integrated 3.3-V/10-mA LDO regulator - used in video security cameras and multi-function printers.

For engineers reviewing the DRV8881PRHRR datasheet, DRV8881PRHRR pinout, DRV8881PRHRR application, or DRV8881PRHRR equivalent, this page delivers verified electrical specs (R_DS(ON) = 330 mΩ HS / 300 mΩ LS at 24 V, 25°C), decay mode configuration (fast/mixed/slow), adaptive blanking time, torque DAC scaling (25–100%), and fault reporting via open-drain nFAULT.

Technical Context

The DRV8881PRHRR implements two independent NMOS H-bridge output stages with integrated current-sense amplifiers, fixed-off-time PWM chopping (10/20/30 µs selectable via TOFF pin), and tri-level decay mode control (ADECAY/BDECAY) for precise winding current regulation. It supports parallel mode (via PARA pin) to combine both bridges for 2.8-A rms output.

Its control architecture uses PWM inputs (AIN1/AIN2/BIN1/BIN2) with internal pulldowns, enabling direct microcontroller interfacing without external logic. Smart tune is excluded - this is the DRV8881P variant, not DRV8881E - and instead offers configurable off-time and torque DAC (TRQ0/TRQ1) for dynamic current scaling without analog reference adjustment.

Key Specifications

Parameter	Value and Actual Design Meaning
Supply Voltage Range	6.5 V to 45 V - supports wide industrial DC bus voltages including 12 V, 24 V, and 36 V systems without external regulators.
Peak Output Current	2.5 A per H-bridge - sets overcurrent protection trip level (IOCP), limiting transient surge capability during startup or stall.
RMS Output Current	1.4 A per H-bridge (2.8 A in parallel mode) - thermal limit at TA = 25°C with proper PCB ground plane; derates with ambient temperature and layout.
High-Side R_DS(ON)	330 mΩ at 24 V, 25°C - determines conduction loss and heating under full-load DC conditions; increases to 440 mΩ at 125°C.
Low-Side R_DS(ON)	300 mΩ at 24 V, 25°C - contributes to total bridge on-resistance and impacts efficiency in slow-decay or brake modes.
Internal LDO Output	3.3 V ±0.3 V, 10 mA - powers external logic or sensors; requires 0.47-µF ceramic bypass capacitor on V3P3 to GND.
Sleep Current	28 µA at 24 V, 25°C - enables ultra-low-power standby in battery-backed or energy-sensitive motion systems.

Pinout & Package

DRV8881PRHRR is housed in a 28-pin WQFN package (5.50 mm × 3.50 mm) with exposed thermal pad (connected to GND). The package supports high-power dissipation via PCB copper area under the pad and is RoHS-compliant.

Pin/Terminal	Circuit Role	Design Meaning
AOUT1 / AOUT2	H-bridge A motor outputs	Drive one winding of a bipolar stepper or terminal of a brushed-DC motor; rated for ±0.7 V beyond VM.
BOUT1 / BOUT2	H-bridge B motor outputs	Drive second winding or second motor; identical voltage/current ratings as A-side outputs.
AIN1 / AIN2 / BIN1 / BIN2	PWM control inputs	Direct logic-level inputs (VIH = 1.6 V min) with internal pulldowns; define forward/reverse/brake/coast states per bridge.
AISEN / BISEN	Current sense inputs	Accept voltage drop across external sense resistors; full-scale trip is 500 mV (at TRQ=100%, VREF=3.3 V).
AVREF / BVREF	Analog current reference inputs	Set full-scale chopping current; 0.3–3.3 V range defines peak current threshold with torque DAC scaling.
TOFF	Off-time select	Tri-level input: Hi-Z = 10 µs, low = 20 µs, high = 30 µs - directly configures PWM chopping period.
ADECAY / BDECAY	Decay mode control	Tri-level pins selecting fast/mixed/slow decay per bridge; critical for torque smoothness and back-EMF handling.
PARA	Parallel mode enable	Logic high connects both H-bridges in parallel to double current capacity (2.8 A rms) for single-motor high-torque drive.
nFAULT	Fault indicator	Open-drain output pulled low on UVLO, OCP, TSD, or CPUV; requires external pullup to V3P3 or VM.
nSLEEP	Power-down control	Active-high input; drives device into 28-µA sleep state; wake-up time is 1.5 ms to operational output.
TRQ0 / TRQ1	Torque DAC select	2-bit digital input scaling full-scale current to 100%/75%/50%/25% - enables dynamic power reduction without reconfiguring VREF.
V3P3	Internal LDO output	Stable 3.3-V supply; max 10-mA load; must be bypassed with 0.47-µF ceramic cap to GND for regulation integrity.
VM / GND / Thermal Pad	Power and ground	Two VM pins and multiple GND pins (including thermal pad) minimize IR drop and improve thermal transfer to PCB.

Key Features

Feature	Design Value
Parallel Mode Operation	Enables dual H-bridges to drive a single motor coil jointly, doubling rms current capability to 2.8 A while retaining single-PWM control simplicity.
Configurable PWM Off-Time	10/20/30 µs selection via TOFF pin allows optimization of current ripple vs. efficiency trade-offs across motor inductance and speed ranges.
Torque DAC Scaling	Hardware-based 2-bit current scaling (25–100%) eliminates need to dynamically adjust AVREF/BVREF voltage, reducing MCU GPIO and DAC resource usage.
Adaptive Blanking Time	Automatically shortens minimum drive pulse width at low currents to prevent waveform distortion and maintain accurate current regulation down to microstep levels.
Integrated 3.3-V LDO Regulator	Eliminates need for external 3.3-V rail; powers microcontroller I/O, position sensors, or logic; includes dedicated bypass capacitor requirement for stability.
Comprehensive Protection Suite	Includes VM undervoltage lockout (6.4 V trip), charge pump UVLO, overcurrent detection (2.5-A threshold), thermal shutdown (150°C), and fault reporting via nFAULT.

Equivalent & Alternatives

The following parts are listed as comparable options for similar dual H-bridge motor driver applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
DRV8880PWPR	Same 28-pin HTSSOP package; identical 2.5-A peak rating but lacks parallel mode and torque DAC; uses PH/EN interface only.	Best suited for cost-sensitive stepper-only designs where PWM control and current scaling are unnecessary.	Select DRV8880PWPR only if PH/EN interface suffices and parallel operation is not required - no pin compatibility with DRV8881PRHRR.
MP6532GQZ	Monolithic dual H-bridge with 3-A peak rating, 4.5–35-V range, and integrated current sensing; no LDO or torque DAC; QFN-24 package.	Targets compact, high-current brushed-DC applications (e.g., portable tools); lacks stepper-specific features like decay tuning.	Choose MP6532GQZ when board space is constrained and 3-A peak is mandatory - but expect redesign for pinout, decoupling, and control logic.

Compared with DRV8881PRHRR, DRV8880PWPR omits parallel mode and torque DAC - limiting flexibility in high-torque or dynamic-load scenarios - while MP6532GQZ trades integrated LDO and decay configurability for higher peak current and smaller footprint, demanding full schematic and layout revision.

FAQ

What is the maximum continuous RMS current per bridge for DRV8881PRHRR?

The DRV8881PRHRR supports 1.4-A rms current per H-bridge at TA = 25°C with adequate PCB copper area for thermal dissipation. In parallel mode (PARA = high), it delivers 2.8-A rms to a single motor winding. Actual achievable rms current depends on ambient temperature, supply voltage, and heatsinking - e.g., at 85°C ambient, derating to ~1.0 A rms per bridge is typical. DRV8881PRHRR's thermal metrics (RθJB = 8.0°C/W) confirm its suitability for compact, high-power-density layouts.

Does DRV8881PRHRR support Smart Tune auto-decay adjustment?

No, DRV8881PRHRR does not support Smart Tune - that feature is exclusive to the DRV8881E variant (PH/EN interface). DRV8881PRHRR is the DRV8881P version, which uses fixed PWM control with user-configurable decay modes (fast/mixed/slow) set via ADECAY and BDECAY pins. Smart Tune requires the ATE pin and PH/EN logic; DRV8881PRHRR substitutes PARA, AIN1/AIN2, and BIN1/BIN2 for PWM-based operation. This distinction is clearly documented in TI's SLVSD19A datasheet.

How is current regulation configured on DRV8881PRHRR?

Current regulation on DRV8881PRHRR uses fixed-off-time PWM chopping, where the trip threshold is set by AVREF/BVREF voltage, sense resistor value, and torque DAC (TRQ0/TRQ1). Full-scale trip voltage at AISEN/BISEN is 500 mV (TRQ=100%), scaling linearly to 125 mV (TRQ=25%). TOFF selects off-time (10/20/30 µs), and ADECAY/BDECAY choose decay mode. Unlike current-mode controllers, DRV8881PRHRR does not require external op-amps or DACs - all regulation is internal and digitally configurable.

What protection features are integrated into DRV8881PRHRR?

DRV8881PRHRR integrates VM undervoltage lockout (6.4 V trip), charge pump undervoltage detection, overcurrent protection (2.5-A threshold with 2-µs deglitch), thermal shutdown (150°C junction), and fault reporting via open-drain nFAULT. It also includes automatic OCP retry (0.5–2 ms delay) and adaptive blanking time to prevent false trips during transient current spikes. These protections operate independently of MCU firmware, ensuring fail-safe behavior even during software hangs - a key requirement for industrial motion systems using DRV8881PRHRR.

Can DRV8881PRHRR drive a single high-current brushed-DC motor?

Yes, DRV8881PRHRR can drive a single high-current brushed-DC motor using parallel mode: tie PARA high, connect AOUT1/AOUT2 and BOUT1/BOUT2 together to the motor terminals, and drive both bridges synchronously with shared AIN1/AIN2 and BIN1/BIN2 signals. This yields 2.8-A rms (vs. 1.4-A rms per bridge), with matched R_DS(ON) and thermal sharing. Note that parallel mode requires identical external components (sense resistors, decoupling) on both sides and disables independent bridge control - confirmed in Section 7.3.1.2 of the DRV8881 datasheet for DRV8881PRHRR.
