Product details
Overview
DRV8952DDWR from Texas Instruments is a four-channel half-bridge motor driver IC with integrated high-side current sensing, 4.5–55 V operation, 50 mΩ RDS(ON) at 24 V/25 °C, 5 A per output (DDW package), and independent PWM/EN control per channel. It drives solenoids, stepper motors, brushed-DC motors, TECs, or BLDC/PMSM motors in industrial automation and medical equipment.
For engineers reviewing the DRV8952DDWR datasheet, DRV8952DDWR pinout, DRV8952DDWR application, or DRV8952DDWR equivalent, key selection factors include its HTSSOP-44 thermal performance, programmable rise/fall time via MODE pin, IPROPI current sense outputs with ±3.5% accuracy at full scale, and fault recovery configuration via OCPM pin.
Technical Context
The DRV8952DDWR implements four independent N-channel half-bridges with charge-pump-driven high-side gates enabling 100% duty-cycle operation. Its integrated current sensing uses high-side MOSFET mirror gain (212 µA/A) to generate proportional IPROPI outputs - one per channel - referenced to VREF for closed-loop regulation.
Protection architecture includes VM UVLO (4.23 V rising), charge pump undervoltage detection, cycle-by-cycle overcurrent protection (7.6 A trip), and thermal shutdown (150 °C). Fault status is reported via open-drain nFAULT with configurable latch-off or auto-retry recovery determined by OCPM voltage level.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 4.5 V to 55 V - supports wide-input industrial power rails without external DC/DC pre-regulation. |
| RDS(ON) (High-Side) | 54 mΩ typ @ 25 °C - enables 5 A continuous output per channel in DDW package with <1.3 W conduction loss. |
| Output Current Rating | 5 A per channel (DDW) - validated under thermal constraints with RθJA = 22.5 °C/W and PCB heatsinking. |
| Current Sense Accuracy | ±3.5% error @ 40–100% rated current - enables reliable closed-loop current control without external shunt calibration. |
| Rise/Fall Time | 70 ns (MODE = 1) or 140 ns (MODE = 0) - selectable edge speed balances EMI reduction vs. switching loss. |
| Fault Recovery Mode | Configurable latch-off or auto-retry - set by OCPM pin voltage, allowing system-level fault handling strategy alignment. |
| Sleep Current | 3 µA max - maintains ultra-low standby power for battery-backed or energy-sensitive systems. |
Pinout & Package
DRV8952DDWR is housed in a thermally enhanced 44-pin HTSSOP (DDW) package (14 mm × 8.1 mm), featuring an exposed thermal pad connected to GND for efficient heat dissipation. Pin functions are validated per TI SLOSE83A datasheet Rev. JANUARY 2025.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN1–IN4 | PWM input | Accepts 1.8/3.3/5.0 V logic; controls high/low state of respective half-bridge output. |
| EN1–EN4 | Enable input | Hi-Z disables output stage; allows individual channel shutdown without affecting others. |
| IPROPI1–IPROPI4 | Current sense output | Proportional current source (212 µA/A) for high-side FET current; requires RIPROPI resistor to ground for voltage conversion. |
| VREF | Regulation reference | Analog input (0.05–3.3 V) setting current limit threshold; used with IPROPI to define ITRIP via equation ITRIP = VREF / (AIPROPI × RIPROPI). |
| MODE | Rise/fall time select | Logic-high selects 70 ns edges; logic-low selects 140 ns - directly tunes switching behavior for EMI or efficiency optimization. |
| OCPM | Fault recovery mode | Voltage level determines whether overcurrent faults trigger latch-off (OCPM < 0.8 V) or auto-retry (OCPM > 2.0 V). |
| nFAULT | Open-drain fault flag | Active-low indicates UVLO, OCP, OTSD, or CPUV; requires external pull-up for system interrupt signaling. |
| nSLEEP | Ultra-low-power control | Logic-low enters 3 µA sleep mode; narrow pulse clears latched faults without full reset. |
Key Features
| Feature | Design Value |
|---|---|
| Four independent half-bridges | Enables simultaneous control of diverse loads - e.g., two brushed-DC motors + one stepper + one solenoid - without cross-talk or shared timing constraints. |
| Integrated high-side current sensing | Eliminates need for four external shunt resistors and op-amp circuits, reducing BOM count, board area, and signal path errors. |
| Programmable output edge rate | 70 ns or 140 ns rise/fall times allow EMI compliance tuning while maintaining 200 kHz PWM capability. |
| Dual supply support (VM + VCC) | VCC pin accepts separate 3.05–5.5 V logic supply, isolating digital interface noise from motor power domain. |
| Comprehensive fault protection | Hardware-enforced safeguards - including VM UVLO, charge pump UV, OCP, and OTSD - prevent damage during brownouts, shorts, or overheating. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar four-channel half-bridge driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DRV8962DDWR | Higher 65 V max VM rating; identical 44-pin HTSSOP footprint and IPROPI functionality. | Better suited for 60 V industrial buses or regenerative braking scenarios where voltage spikes exceed 55 V. | Select DRV8962DDWR when system VM may transiently exceed 55 V; otherwise DRV8952DDWR offers optimal cost/performance at ≤55 V. |
| DRV8955PWPR | 28-pin HTSSOP (PWP), 4 A/channel rating, no VCC or MODE pins, fixed 140 ns edge rate. | Targeted at space-constrained designs with lower current demands and simplified control requirements. | Choose DRV8955PWPR only if 4 A/channel suffices and board layout cannot accommodate 44-pin DDW package or requires fewer control signals. |
Compared with DRV8952DDWR, DRV8962DDWR extends voltage headroom without sacrificing feature parity, while DRV8955PWPR trades current capacity and configurability for compactness - making DRV8952DDWR the balanced choice for 48 V systems needing full programmability and 5 A drive.

FAQ
What is the maximum continuous output current per channel for DRV8952DDWR?
The DRV8952DDWR supports up to 5 A continuous current per channel when implemented in the HTSSOP-44 (DDW) package, validated under recommended thermal conditions (RθJA = 22.5 °C/W) and ambient temperatures up to 125 °C. This rating assumes proper PCB copper area, thermal vias under the exposed pad, and airflow consistent with datasheet Section 8.1.
How does the IPROPI current sense output work on DRV8952DDWR?
The DRV8952DDWR provides four dedicated IPROPI pins (IPROPI1–IPROPI4), each sourcing a current proportional to its corresponding high-side FET current (212 µA/A). To convert to voltage, connect each IPROPI pin to ground via an external resistor (RIPROPI); the resulting VIPROPI = IHS × 212 µA/A × RIPROPI enables ADC-based current monitoring with ±3.5% accuracy at full scale.
Can DRV8952DDWR drive a stepper motor, and how is microstepping achieved?
Yes, DRV8952DDWR can drive one bipolar stepper motor using two half-bridges (e.g., OUT1/OUT2 for phase A, OUT3/OUT4 for phase B). Microstepping is achieved externally by applying variable-duty-cycle PWM to the INx pins while regulating current via VREF and IPROPI feedback - the device's fixed 16 µs off-time chopper supports smooth current ramping essential for sub-step resolution.
What protection features are integrated into DRV8952DDWR?
DRV8952DDWR integrates VM undervoltage lockout (4.23 V rising), charge pump undervoltage detection, cycle-by-cycle overcurrent protection (7.6 A trip), and thermal shutdown (150 °C junction). All faults assert the open-drain nFAULT pin; recovery behavior (latch-off vs. auto-retry) is configured via the OCPM pin voltage per datasheet Section 5.5.
Is DRV8952DDWR pin-compatible with any other Texas Instruments drivers?
Yes, DRV8952DDWR in the DDW package is pin-to-pin compatible with DRV8962DDWR, differing only in maximum VM rating (55 V vs. 65 V) and minor electrical specs. This allows direct replacement in existing layouts when higher voltage margin is required, without PCB redesign or firmware changes.
