Product details
Overview
DRV8870DDA from Texas Instruments is a monolithic H-bridge brushed DC motor driver IC designed for bidirectional control of one DC motor or one winding of a stepper motor. It operates from 6.5 V to 45 V, delivers up to 3.6-A peak output current, features integrated current regulation via VREF/ISEN, and includes VM undervoltage lockout, overcurrent protection, and thermal shutdown - used in printer paper feed mechanisms, appliance pump actuators, and industrial valve positioning.
For engineers reviewing the DRV8870DDA datasheet, DRV8870DDA pinout, DRV8870DDA application, or DRV8870DDA equivalent, key selection criteria include its 8-pin HSOP PowerPAD™ package, 565-mΩ typical RDS(on) (HS+LS), PWM-compatible dual logic inputs (IN1/IN2), automatic fault recovery behavior, and support for slow-decay braking and coast modes in mechatronic motion control systems.
Technical Context
The DRV8870DDA integrates four N-channel MOSFETs in an H-bridge topology with internal charge pump enabling full enhancement of high-side FETs across its 6.5–45 V VM range. Its current regulation uses analog VREF (0.3–5 V) and external sense resistor on ISEN to set precise ITRIP, enforcing slow-decay current limiting for up to 25 µs per cycle.
Control logic accepts static or PWM-driven IN1/IN2 signals (0–200 kHz), with built-in 1-ms sleep entry on dual-low input, 50-µs turn-on time, and 220-ns dead-time insertion to prevent shoot-through. Protection circuitry includes UVLO (6.1–6.5 V thresholds), OCP (trip at 3.7–6.4 A), and TSD (150–175 °C with 40 °C hysteresis), all enabling automatic recovery upon fault clearance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage (VM) | 6.5 V to 45 V - supports wide-input industrial power rails including 12 V, 24 V, and 36 V nominal systems |
| Peak Output Current | 3.6 A - enables driving medium-torque DC motors (e.g., 24 V, 1.5 N·m) without external current boosting |
| RDS(on) (HS + LS) | 565 mΩ typical - limits conduction loss to ≤1.8 W at 3.6 A, reducing heatsink requirements |
| Current Regulation | VREF-adjustable ITRIP - sets precise motor stall/startup current limit using external sense resistor, stabilizing supply voltage during transients |
| Logic Inputs | IN1/IN2 with internal 100-kΩ pulldowns - simplifies interface to microcontrollers; supports 0–200 kHz PWM for speed control |
| Fault Recovery | Automatic resume after UVLO/OCP/TSD clearance - eliminates need for external reset circuitry in standalone motion modules |
| Thermal Resistance | RθJA = 41.1 °C/W - requires ≥4.9 × 6.0 mm thermal pad soldered to multi-layer ground plane for >2 A continuous operation |
Pinout & Package
DRV8870DDA is housed in an 8-pin HSOP (Heat Sink Overmolded Package) with exposed thermal pad (PowerPAD™), measuring 4.90 mm × 6.00 mm. The package requires soldering the thermal pad to PCB ground for thermal performance compliance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| GND (Pin 1) | Logic ground reference | Connects to system digital ground; serves as return path for logic-level circuitry and internal bias networks |
| IN2 (Pin 2) | H-bridge control input | Accepts 0–5.5 V logic signal; combined with IN1 determines forward/reverse/brake/coast states per Table 1 |
| IN1 (Pin 3) | H-bridge control input | Primary logic input with internal 100-kΩ pulldown; enables sleep mode when both IN1 and IN2 are low for ≥1 ms |
| VREF (Pin 4) | Analog current-set reference | 0.3–5 V input setting ITRIP = (VREF / 10) / RSENSE; higher VREF increases current limit linearly |
| VM (Pin 5) | Main power supply input | 6.5–45 V motor and IC supply; requires local 0.1-µF ceramic + bulk capacitance; powers internal charge pump |
| OUT1 (Pin 6) | H-bridge high-side output | Connects directly to motor terminal; sinks current during reverse/brake; body diode provides freewheeling path |
| ISEN (Pin 7) | Current-sense feedback node | High-current ground return path; connects to low-inductance sense resistor; voltage proportional to motor current × 10× gain |
| OUT2 (Pin 8) | H-bridge low-side output | Connects directly to motor terminal; sources current during forward/brake; complements OUT1 for bidirectional drive |
Key Features
| Feature | Design Value |
|---|---|
| Integrated charge pump | Enables full enhancement of N-channel high-side FETs across entire 6.5–45 V VM range without external bootstrap components |
| Programmable current regulation | VREF-based ITRIP setting allows precise motor current limiting independent of supply voltage or temperature drift |
| Low-power sleep mode | 10-µA VM supply current when both IN1 and IN2 held low ≥1 ms - extends battery life in portable motorized devices |
| Automatic fault recovery | UVLO/OCP/TSD faults clear autonomously after condition removal - eliminates need for host MCU intervention or reset sequencing |
| Dead-time control | 220-ns fixed dead time prevents shoot-through during switching transitions - ensures robust operation without external timing components |

Equivalent & Alternatives
The following parts are listed as comparable options for similar brushed DC motor driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TB6612FNG | Lower VM range (2.5–13.5 V); 1.2-A continuous current; no integrated current regulation; separate VCC logic supply required | Suitable only for low-voltage battery-powered robots or toys; lacks fault recovery and thermal management for industrial use | Select when cost-sensitive, low-power, and 12 V max systems dominate; avoid for 24 V+ or current-critical applications |
| DRV8871DDA | Same 8-pin HSOP package and pinout; identical RDS(on) and protection features; differs only in current rating (4.5-A peak vs. 3.6-A) | Direct drop-in replacement where higher peak current is needed without layout change; same thermal design and PCB footprint | Choose DRV8871DDA if motor startup surge exceeds 3.6 A but board space and thermal constraints prohibit redesign |
Compared with TB6612FNG, DRV8870DDA supports wider voltage, higher current, and autonomous fault handling; compared with DRV8871DDA, it trades 0.9-A peak margin for tighter current regulation accuracy and lower thermal stress in sustained 2–3 A loads.

FAQ
What is the maximum continuous current the DRV8870DDA can deliver without forced cooling?
The DRV8870DDA supports up to 2 A RMS continuous current on a standard 2-layer FR-4 PCB with full thermal pad soldering and ≥4 thermal vias, based on its RθJA = 41.1 °C/W and 150 °C junction limit. At 25 °C ambient, this corresponds to ~1.4 W dissipation. Derating applies above 50 °C ambient or with reduced copper area. The 3.6-A rating is peak-only (≤100 ms).
How does current regulation work on the DRV8870DDA, and what external components are required?
DRV8870DDA implements analog current regulation using VREF (Pin 4) and ISEN (Pin 7). A precision sense resistor (e.g., 0.15 Ω, 1 W) connects between ISEN and GND. ITRIP = VREF / (10 × RSENSE). For example, 3.3 V on VREF with 0.15 Ω yields 2.2 A trip. No op-amps or comparators are needed - regulation is fully internal.
Can the DRV8870DDA be used with a 48 V supply?
No - the absolute maximum VM rating for DRV8870DDA is 50 V, but recommended operating voltage is strictly limited to 6.5 V to 45 V per datasheet Section 6.3. Operating at 48 V violates specifications, risks premature failure due to overstress, and voids TI's reliability guarantees. Use DRV8871 or DRV8876 for 48 V systems.
Does the DRV8870DDA require external bootstrap capacitors for high-side drive?
No - the DRV8870DDA integrates a charge pump that generates boosted gate drive voltage internally, eliminating the need for external bootstrap capacitors or diodes. This simplifies layout and improves reliability in high-voltage (up to 45 V) brushed DC motor applications.
What happens when an overcurrent fault occurs on the DRV8870DDA, and how long does recovery take?
When output current exceeds IOCP (3.7–6.4 A) for longer than tOCP (1.5 µs), DRV8870DDA disables all FETs and enters retry mode for tRETRY = 3 ms. After this interval, it automatically re-enables outputs according to IN1/IN2 state. If fault persists, cycle repeats. This behavior is fully autonomous and requires no host MCU action.
