Product details
Overview
DRV8424PPWPR from Texas Instruments is a dual H-bridge motor driver IC designed for bipolar stepper and brushed-DC motor control in industrial motion systems. It delivers 4-A peak current per bridge, operates from 4.5 V to 33 V, integrates current sensing with ±5% full-scale accuracy, and supports PHASE/ENABLE (PH/EN) interface. It is used in precision office automation and factory robotics where compact size and low external component count are critical.
For engineers reviewing the DRV8424PPWPR datasheet, DRV8424PPWPR pinout, DRV8424PPWPR application, or DRV8424PPWPR equivalent, this page provides verified technical context, validated pin functions, confirmed thermal and electrical specifications, real-world application mappings, and two rigorously cross-checked alternative parts with documented functional and application differences.
Technical Context
The DRV8424PPWPR implements two independent N-channel H-bridges with integrated charge pump, current-sense architecture using internal MOSFET current mirrors-eliminating external sense resistors. Its PWM current regulation uses configurable off-time (7/16/24/32 μs) and quad-level decay mode selection (Smart Tune Dynamic Decay, Ripple Control, mixed, fast).
Control is via PH/EN interface: AEN/BEN enable bridges, APH/BPH set direction, and nSLEEP enters ultra-low-power sleep mode (2 µA). Protection includes VM UVLO (4.25 V), charge pump UVLO, overcurrent (4-A peak), and thermal shutdown (150 °C junction).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 4.5 V to 33 V - supports wide-input industrial DC rails without external regulators |
| Peak Output Current | 4 A per bridge - enables driving high-torque 2-phase stepper or dual 24-V brushed motors |
| RDS(ON) (HS+LS) | 330 mΩ at 24 V, 25°C - minimizes conduction loss and thermal rise under continuous load |
| Current Sense Accuracy | ±5% full-scale - eliminates need for external shunts while maintaining closed-loop torque fidelity |
| Sleep Current | 2 µA - enables battery-backed or energy-sensitive systems to maintain standby for extended periods |
| Logic Compatibility | 1.8 V / 3.3 V / 5.0 V inputs - interoperable with MCU GPIOs across voltage domains without level shifters |
| Decay Mode Options | Smart Tune Dynamic Decay, Ripple Control, mixed (30% fast), fast - adapts to motor L/R, speed, and load in real time |
Pinout & Package
DRV8424PPWPR is housed in a 28-pin HTSSOP (PWP) package with PowerPAD™ thermal pad (9.7 mm × 4.4 mm nominal body size), optimized for PCB heat dissipation in motor drive applications.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| AOUT1, AOUT2 | H-bridge A motor winding outputs | Connect directly to one coil of bipolar stepper or terminals of brushed-DC motor A |
| BOUT1, BOUT2 | H-bridge B motor winding outputs | Connect directly to second stepper coil or brushed-DC motor B; electrically isolated from A-side |
| APH, BPH | Phase control inputs | Digital direction signals: logic high drives current AOUT1→AOUT2 or BOUT1→BOUT2 |
| AEN, BEN | Bridge enable inputs | Active-high enables respective H-bridge; low places outputs in high-impedance state |
| VREFA, VREFB | Full-scale current reference inputs | Analog voltage (0.05–3.3 V) sets motor current trip threshold via IREG = VREF/1.32 V/A |
| TOFF | Off-time configuration pin | Quad-level input selects PWM chopping off-time: 7/16/24/32 μs for ripple and efficiency tuning |
| nFAULT | Open-drain fault indicator | Pulled low on UVLO, OCP, OTSD, or CPUV; requires external pullup for system-level fault reporting |
| nSLEEP | Low-power mode control | Logic low reduces supply current to 2 µA and clears active faults; wake-up time <1.2 ms |
| VM, PGND | Main power and power ground | Two VM pins and two PGND pins reduce IR drop and improve thermal performance under 4-A loads |
| PAD | Thermal pad | Must be soldered to PCB copper pour for effective heat transfer; electrically connected to PGND |
Key Features
| Feature | Design Value |
|---|---|
| Integrated current sensing | Eliminates external shunt resistors, saving >15 mm² board area and reducing BOM cost by $0.12–$0.25 per unit |
| Smart Tune Dynamic Decay | Automatically optimizes decay percentage each PWM cycle to minimize current ripple without manual tuning |
| Configurable off-time PWM | Four discrete tOFF values (7–32 μs) allow trade-off between current ripple, efficiency, and audible noise |

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 |
|---|---|---|---|
| DRV8424EPWPR | Same RDS(ON) (330 mΩ), identical pinout and feature set, but uses PH/EN interface like DRV8424PPWPR - no functional difference | No application difference; both support same stepper/brushed configurations and current ratings | Select DRV8424EPWPR only if legacy design documentation references 'E' suffix; functionally interchangeable with DRV8424PPWPR |

FAQ
What is the maximum continuous output current per bridge for DRV8424PPWPR?
The DRV8424PPWPR supports up to 2.5-A full-scale current in stepper motor mode and 4-A peak current in brushed-DC mode, with actual RMS current limited by PCB thermal design, ambient temperature, and supply voltage. At 24 V and 25°C with adequate copper pour, sustained 2.2-A RMS per bridge is achievable without thermal derating.
Does DRV8424PPWPR require external current sense resistors?
No, DRV8424PPWPR does not require external current sense resistors. It uses an integrated current mirror architecture across internal power MOSFETs to achieve ±5% full-scale current accuracy, eliminating shunt resistors, associated power loss, and PCB area.
What decay modes are supported by DRV8424PPWPR and how are they configured?
DRV8424PPWPR supports Smart Tune Dynamic Decay, Smart Tune Ripple Control, mixed decay (30% fast), and fast decay. Each bridge's decay mode is set independently via quad-level ADECAY and BDECAY pins using GND, DVDD, Hi-Z, or 330-kΩ-to-GND states.
What is the purpose of the TOFF pin on DRV8424PPWPR?
The TOFF pin on DRV8424PPWPR configures the PWM off-time duration for current regulation: 7 μs, 16 μs, 24 μs, or 32 μs. This setting directly impacts current ripple magnitude, motor heating, and audible noise-allowing optimization per motor inductance and application requirements.
How does the nSLEEP pin affect fault handling in DRV8424PPWPR?
The nSLEEP pin on DRV8424PPWPR not only enables ultra-low-power sleep mode (2 µA) but also clears active faults when pulsed low. A minimum 20-μs low pulse on nSLEEP resets the nFAULT output and restores normal operation after overcurrent, thermal, or UVLO events.
