Product details
Overview
DRV8873SPWPT from Texas Instruments is a 24-pin HTSSOP H-bridge motor driver IC for industrial brushed DC motors, stepper windings, or solenoid loads. It delivers up to 10-A peak current with 4.5 V to 38 V supply range, 150 mΩ total RDS(ON) at 25°C, and integrated current mirror sensing. It supports PH/EN, PWM, or independent half-bridge control modes in ePOS, ATMs, and factory automation.
For engineers reviewing the DRV8873SPWPT datasheet, DRV8873SPWPT pinout, DRV8873SPWPT application, or DRV8873SPWPT equivalent, this page provides verified technical context, real-world design meanings of key specs, validated pin functions, confirmed alternative parts with functional differences, and supply support for production-grade motor control designs.
Technical Context
The DRV8873SPWPT integrates four N-channel MOSFETs in an H-bridge topology with configurable control logic (PH/EN, PWM, or independent half-bridge), enabling bidirectional motor drive or dual solenoid actuation. Its current mirror outputs (IPROPI1/IPROPI2) provide analog-scaled high-side current feedback without external shunt resistors.
It features hardware-selectable operation mode via MODE pin (ground = PH/EN, DVDD = PWM, 200 kΩ to GND = independent), built-in 400-kHz charge pump for high-side gate drive, and fault reporting via open-drain nFAULT and SPI registers. Protection includes VM UVLO (4.45 V trip), overcurrent (10 A), thermal shutdown (175 °C), and open-load detection.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Range | 4.5 V to 38 V - supports wide-input industrial power rails including 12 V, 24 V, and 36 V systems without external regulation. |
| Peak Output Current | 10 A - enables direct driving of medium-power DC motors (e.g., 24 V/50 W) without external FETs or heatsinking in short bursts. |
| RDS(ON) (HS + LS) | 150 mΩ at 25°C - reduces conduction loss to ≤1.5 W at 5 A, minimizing thermal rise in compact HTSSOP package. |
| Current Mirror Accuracy | ±5% error ≥1 A - allows precise closed-loop current regulation using low-cost op-amp circuitry instead of high-wattage sense resistors. |
| Sleep Current | 15 µA typical - extends battery life in portable or energy-sensitive applications like motorized blinds or adjustable furniture. |
| Fault Reporting | nFAULT (open-drain) + SPI register readout - provides both immediate system-level interrupt signaling and detailed diagnostic data for root-cause analysis. |
| Logic Compatibility | 1.8 V / 3.3 V / 5 V inputs - interfaces directly with microcontrollers, FPGAs, or PLC I/O without level-shifting components. |
Pinout & Package
DRV8873SPWPT uses a 24-pin HTSSOP PowerPAD™ package (7.70 mm × 4.40 mm) with exposed thermal pad for enhanced heat dissipation in motor drive applications.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| OUT1, OUT2 | H-bridge output terminals | Drive motor terminals or solenoid loads; each supports bidirectional current flow up to 10 A peak with internal FETs. |
| EN/IN1, PH/IN2 | Control logic inputs | Determine bridge state (forward/reverse/brake/Hi-Z) per selected mode; include internal pulldowns for default-safe startup. |
| nFAULT | Fault indicator output | Open-drain signal pulled low on UVLO, OCP, TSD, or open-load fault; requires external pullup for MCU interrupt input. |
| nSLEEP | Low-power enable | Logic-low entry into 15 µA sleep mode; wake-up time is 1.5 ms - suitable for duty-cycled motion control. |
| DISABLE | Bridge disable input | Logic-high forces Hi-Z on both outputs regardless of control inputs - used for emergency stop or safety interlock. |
| IPROPI1, IPROPI2 | Current mirror outputs | Analog current proportional to respective high-side FET current (k = 1100 A/A); enables real-time load monitoring without shunt resistor. |
| VM | Motor power supply | Main high-current path (up to 10 A); requires local 0.1 µF ceramic + bulk capacitor to suppress switching noise and sustain peak loads. |
| DVDD | Digital regulator output | Internal 5-V rail for logic; bypassed with 1 µF ceramic capacitor - powers control circuitry and interface logic independently of VM. |
Key Features
| Feature | Design Value |
|---|---|
| Configurable control interface | Hardware-selectable PH/EN, PWM, or independent half-bridge modes via MODE pin - eliminates firmware dependency for basic motion control. |
| Integrated current mirror | 1100× scaling factor with ±5% accuracy ≥1 A - replaces 5-W shunt resistors and enables low-cost current feedback for torque regulation. |
| Programmable slew rate | 8-step adjustment (2.6–53.2 V/µs) via SR pin or SPI - balances EMI reduction against switching loss in noisy industrial environments. |
| Built-in protection suite | UVLO, OCP (10 A), TSD (175 °C), open-load detection, and short-to-battery/ground - reduces need for external supervision circuitry. |
| Spread-spectrum clocking | Applies to internal oscillator and charge pump - lowers peak radiated emissions by spreading energy across frequency band per CISPR 25 Class 5. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar H-bridge motor driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DRV8876PWP | Same 24-pin HTSSOP package, 10-A peak, but adds adaptive dead-time control and higher RDS(ON) (190 mΩ). | Preferred where dynamic dead-time optimization improves efficiency at varying loads; less suitable for space-constrained layouts requiring minimal BOM count. | Select DRV8876PWP if adaptive timing is needed for variable-speed BLDC commutation; otherwise DRV8873SPWPT offers simpler configuration and lower conduction loss. |
| TB9051FTG | 40-V max, 3.5-A continuous (7-A peak), 56-pin QFN, integrated current sense amplifier, CAN interface. | Targeted at automotive body control modules requiring CAN diagnostics and AEC-Q100 qualification; not drop-in compatible due to pin count and protocol stack. | Choose TB9051FTG only for automotive safety-critical systems needing CAN bus integration; DRV8873SPWPT remains optimal for cost-sensitive industrial motion control. |
Compared with DRV8873SPWPT, DRV8876PWP improves timing precision at the cost of higher conduction loss, while TB9051FTG adds automotive-grade communication and qualification but sacrifices peak current capability and increases footprint complexity.

FAQ
What is the maximum continuous current rating for DRV8873SPWPT?
The DRV8873SPWPT is rated for 10-A peak current, but continuous current depends on PCB layout, thermal management, and ambient temperature. With proper copper area and airflow, it supports up to 5.5 A continuous at 25°C ambient and 13.5 V supply, based on RDS(ON) derating and thermal resistance (RθJA = 27.8 °C/W). Always verify junction temperature using measured board conditions in final design.
Does DRV8873SPWPT support SPI communication out of the box?
No - DRV8873SPWPT is the hardware-interface variant (H-version) with MODE pin control and no dedicated SPI pins. The SPI-capable version is DRV8873SPWPR. DRV8873SPWPT uses EN/IN1, PH/IN2, and MODE pin for configuration and reports faults only via nFAULT; it does not include SCLK, SDI, SDO, or nSCS pins.
How does the current mirror on DRV8873SPWPT work in practice?
The DRV8873SPWPT provides two mirrored current outputs (IPROPI1 and IPROPI2), each scaled 1100× relative to its respective high-side FET current. For example, 5 A through OUT1 yields ~4.55 mA at IPROPI1. This analog current can be converted to voltage using a grounded sense resistor (e.g., 100 Ω → 0.455 V), enabling real-time current monitoring with standard op-amps - eliminating need for high-power shunts.
Can DRV8873SPWPT drive a stepper motor?
Yes - DRV8873SPWPT can drive one winding of a bipolar stepper motor in full-step or half-step mode using PH/EN or PWM control. It does not support microstepping or dual-winding coordination internally; external controller must sequence IN1/IN2 signals to energize windings in correct polarity and timing. Thermal limits and current regulation must be managed per phase.
What protection features are active during DRV8873SPWPT sleep mode?
In sleep mode (nSLEEP = low), UVLO, charge pump undervoltage, and thermal shutdown remain active. Overcurrent protection (OCP) and open-load detection are disabled - the device cannot detect faults while asleep. Upon wake-up (nSLEEP high), all protections re-enable within 1.5 ms. nFAULT remains high-impedance until full initialization completes.
