Product details
Overview
DRV8411PWPR from Texas Instruments is a dual H-bridge motor driver IC designed for precise current-regulated control of brushed DC or bipolar stepper motors in space-constrained, battery-powered systems. It delivers 4A peak output current per bridge, features 400mΩ typical total RDS(on) (HS + LS), operates from 1.65V to 11V, and integrates current regulation via external sense resistors on AISEN/BISEN pins - enabling robust stall/startup current limiting in POS printers and robotics.
For engineers reviewing the DRV8411PWPR datasheet, DRV8411PWPR pinout, DRV8411PWPR application, or DRV8411PWPR equivalent, key selection considerations include its dual-bridge PWM interface with 100kHz max frequency, ultra-low 40nA sleep current at 5V, integrated UVLO/OCP/TSD protection, and compatibility with 1.8V/3.3V/5V logic levels - critical for low-voltage embedded motor control designs.
Technical Context
The DRV8411PWPR implements two independent N-channel H-bridges with internal charge pump enabling full enhancement of high-side FETs down to 1.65V supply, supporting 100% duty-cycle operation. Each bridge uses four discrete N-MOSFETs with matched 200mΩ typical RDS(on) per FET, and employs automatic dead-time insertion (400ns) to prevent shoot-through during switching transitions.
Current regulation operates via comparator-based chopping: xISEN pin voltage is compared to a 200mV internal reference, triggering low-side slow-decay braking for tOFF = 20µs when motor current exceeds ITRIP. Fault handling includes auto-retry OCP (4.2µs deglitch, 1.6ms retry), thermal shutdown at 153–193°C, and VM undervoltage lockout with 100mV hysteresis.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.65 V to 11 V - supports single-cell Li-ion, 3.3V logic rails, and low-battery operation in portable devices. |
| Peak Output Current | 4 A per bridge - enables direct drive of medium-power DC motors (e.g., 12V/2A fans) without external current boosting. |
| Total RDS(on) | 400 mΩ (typical, 25°C) - reduces conduction loss and thermal rise; HS + LS combined resistance improves efficiency vs. DRV8833C (1735mΩ). |
| Sleep Current | ≤ 40 nA at VVM = 5 V - extends battery life in always-on smart locks and security cameras during idle periods. |
| PWM Frequency Support | 0 to 100 kHz - allows fine-grained speed control of stepper motors and smooth torque modulation in robotics joints. |
| Current Sense Threshold | 200 mV ±15 mV - sets precise ITRIP via external resistor (RSENSE = 0.2 V / ITRIP); eliminates need for external op-amps or ADCs. |
| Fault Reporting | Open-drain nFAULT pin - asserts low during UVLO, OCP, or TSD; simplifies system-level fault detection with single pull-up resistor. |
Pinout & Package
DRV8411PWPR is packaged in a 16-pin HTSSOP (PWP) with PowerPAD™, measuring 5.0 mm × 6.4 mm (body size), optimized for thermal dissipation in compact motor control PCBs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| AIN1, AIN2, BIN1, BIN2 | H-bridge control inputs | Logic-level inputs (1.8V/3.3V/5V compatible) with internal pulldown; define forward/reverse/brake/coast states per bridge. |
| AOUT1, AOUT2, BOUT1, BOUT2 | Bridge output terminals | Drive motor windings directly; support parallel configuration (A+B outputs tied) to halve effective RDS(on). |
| AISEN, BISEN | Current sense feedback | Accept voltage drop across external shunt resistor; disable current regulation by tying to GND if unused. |
| nSLEEP | Power management input | Active-high enable; entering sleep mode reduces VM current to ≤40nA - critical for battery longevity. |
| nFAULT | Fault status indicator | Open-drain output pulled low during UVLO/OCP/TSD; requires external pullup for system-level fault monitoring. |
| VM | Main power input | Supplies both IC logic and motor winding bias; requires 10µF bulk + 0.1µF ceramic bypass capacitors. |
| GND & Thermal Pad | Reference and thermal path | Must be connected to system ground plane; thermal pad enhances heat transfer to PCB copper area. |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent H-bridges | Enables simultaneous control of two DC motors or one bipolar stepper - no external logic required for phase sequencing. |
| Integrated current regulation | Chopping-based ITRIP limit using 200mV reference eliminates external current-sense amplifiers and reduces BOM count. |
| Charge-pump voltage boost | Allows full gate enhancement of high-side N-FETs at VM ≥1.65V - supports single-cell Li-ion and 1.8V microcontroller interfaces. |
| Auto-retry overcurrent protection | Re-enables bridge after 1.6ms retry interval if fault clears - prevents latch-up while maintaining system responsiveness. |
| Ultra-low sleep quiescent current | ≤40nA at 5V enables multi-year battery life in electronic smart locks and IoT actuators with infrequent motion cycles. |

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 |
|---|---|---|---|
| DRV8411A | Identical electrical specs and pinout; same 400mΩ RDS(on), 4A peak, and current regulation architecture. | No functional difference - DRV8411A is a variant with identical performance and package options (HTSSOP/WQFN). | Select DRV8411A only if specific qualification or lot traceability requirements mandate the 'A' suffix per TI documentation. |
| DRV8833 | Higher RDS(on) (360mΩ/bridge vs. 400mΩ total for DRV8411PWPR), lower 1.5A peak current, no integrated current regulation. | Suitable for lower-power loads (e.g., toy motors) where current limiting is handled externally or not required. | Choose DRV8833 only for cost-sensitive, low-current applications where 4A capability and on-chip current regulation are unnecessary. |
Compared with DRV8411A, DRV8411PWPR offers identical performance but may differ in manufacturing lot or qualification status; compared with DRV8833, it provides double the peak current, integrated current regulation, and lower total conduction loss - making it superior for demanding battery-powered motion control.

FAQ
What is the maximum continuous output current rating for DRV8411PWPR?
The DRV8411PWPR is rated for 4A peak output current per H-bridge. Continuous current depends on thermal design: with proper PCB copper area and airflow, it supports ~2.5A continuous per bridge at 25°C ambient. Derating is required above 85°C ambient or with limited heatsinking - refer to RθJA = 45.1°C/W (HTSSOP) and thermal shutdown threshold of 153–193°C.
Does DRV8411PWPR support parallel bridge operation for higher current?
Yes, DRV8411PWPR supports parallel bridge configuration: AIN1/BIN1 and AIN2/BIN2 are tied together, and AOUT1/BOUT1 and AOUT2/BOUT2 are connected to common nodes. This halves effective RDS(on) to ~200mΩ and doubles current capacity. However, current regulation must be disabled (AISEN/BISEN tied to GND) in this mode per TI documentation.
How does the current regulation feature work on DRV8411PWPR?
DRV8411PWPR implements current regulation by comparing voltage on AISEN/BISEN pins to a 200mV internal reference. When the sense resistor voltage reaches this threshold, the device enters low-side slow-decay braking for 20µs (tOFF). The trip current is set by RSENSE = 0.2 V / ITRIP; for example, a 0.1Ω resistor yields 2A ITRIP. This protects motors during startup and stall conditions without external circuitry.
What logic voltage levels are compatible with DRV8411PWPR inputs?
DRV8411PWPR accepts 1.8V, 3.3V, and 5V logic inputs on AIN1, AIN2, BIN1, BIN2, and nSLEEP pins. Input logic low is defined as ≤0.4V, logic high as ≥1.45V, with hysteresis (100mV on nSLEEP, 50mV on others) for noise immunity. Internal pulldown resistors (100kΩ typical) ensure safe default state when inputs are floating.
Can DRV8411PWPR operate from a single 1.8V supply?
Yes, DRV8411PWPR operates from 1.65V to 11V on VM, making it compatible with single 1.8V supplies. Its integrated charge pump enables full gate drive of high-side N-FETs even at this low rail, ensuring reliable H-bridge operation. However, peak output current is reduced at low VM due to lower drive strength and increased RDS(on) - consult Figure 7-3/7-4 for temperature- and voltage-dependent RDS(on) data.
