Product details
Overview
DRV8952PWPR from Texas Instruments is a 28-pin HTSSOP four-channel half-bridge driver IC designed for industrial motor and solenoid control. It operates from 4.5 V to 55 V, delivers up to 4 A per output, features 58 mΩ low-side and 54 mΩ high-side RDS(ON) at 25 °C, and integrates proportional current sense outputs (IPROPI) with ±5% accuracy at full scale - used in PLCs, TEC drivers, and brushed-DC motor modules.
For engineers reviewing the DRV8952PWPR datasheet, DRV8952PWPR pinout, DRV8952PWPR application, or DRV8952PWPR equivalent, this page delivers verified package mapping (HTSSOP-28), confirmed thermal performance (RθJA = 24.5 °C/W), validated current regulation behavior (fixed 16 µs off-time, VREF-based ITRIP), and real-world fault handling (OCP latch-off/auto-retry via OCPM pin).
Technical Context
The DRV8952PWPR implements four independent N-channel half-bridges with integrated charge pump for 100% duty-cycle high-side drive and internal LDO (DVDD = 5.0 V). Its logic inputs accept 1.8 V/3.3 V/5.0 V levels, and ENx/INx pins support both static and PWM control with programmable dead time (300 ns) and rise/fall times (140 ns).
Current sensing is implemented via high-side MOSFET mirror (AIPROPI = 212 µA/A), with regulation threshold set by VREF voltage (0.05–3.3 V) and internal transimpedance gain (KV = 0.66 V/A). Protection includes VM UVLO (4.23 V rising), charge pump undervoltage detection, overcurrent trip (7.6 A), and thermal shutdown (150 °C).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 4.5 V to 55 V - supports wide industrial input rails including 12 V, 24 V, and 48 V systems without external regulators. |
| Max Output Current (per channel) | 4 A - achievable in PWP package with proper PCB thermal design and ambient ≤125 °C. |
| RDS(ON) (High-Side, 25 °C) | 54 mΩ - enables <1.2 W conduction loss per FET at 4 A, reducing heatsink requirements. |
| RDS(ON) (Low-Side, 25 °C) | 58 mΩ - complements high-side for balanced power stage efficiency in H-bridge configurations. |
| Current Sense Accuracy | ±5% at 100% rated current - sufficient for closed-loop current limiting and load monitoring without external shunt calibration. |
| Thermal Resistance (RθJA) | 24.5 °C/W - defines junction-to-ambient temperature rise under standard JEDEC PCB conditions (2s2p). |
| Fault Response Time | 2.2 µs OCP detection delay - ensures fast response to short-circuit events before MOSFET destruction. |
Pinout & Package
DRV8952PWPR uses a thermally enhanced 28-pin HTSSOP (PWP) package (9.7 mm × 6.4 mm), with exposed thermal pad connected to system ground for improved heat dissipation. Pin functions are validated per TI SLOSE83A datasheet Rev. JANUARY 2025.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN1–IN4 | PWM input control | Accepts 1.8 V–5.5 V logic; directly drives gate drivers for high-/low-side FET switching. |
| EN1–EN4 | Channel enable | Hi-Z output state when low; enables/disables each half-bridge independently without affecting others. |
| OUT1–OUT4 | Half-bridge output | Each connects to one terminal of solenoid, motor winding, or TEC; rated for 55 V max transient. |
| PGND12, PGND34 | Power ground return | Dual isolated ground paths reduce current-loop interference between channel pairs 1&2 and 3&4. |
| VREF | Current regulation reference | Analog input (0.05–3.3 V) sets ITRIP threshold; 20 nA leakage enables high-impedance divider networks. |
| nFAULT | Open-drain fault indicator | Pulled low during UVLO, OCP, or OTSD; requires external pull-up to DVDD or VCC for system-level interrupt signaling. |
| nSLEEP | Ultra-low-power mode control | Logic high enables operation; logic low reduces supply current to 3 µA - ideal for battery-backed standby states. |
Key Features
| Feature | Design Value |
|---|---|
| Four independent half-bridges | Enables simultaneous control of two brushed-DC motors, one stepper, or four solenoids - no inter-channel timing constraints. |
| Integrated current sense & regulation | Eliminates need for external shunts or op-amps; supports fixed off-time chopping with user-set ITRIP via VREF voltage. |
| Programmable fault recovery | OCPM pin selects latch-off (requires nSLEEP reset pulse) or auto-retry (4.1 ms retry interval) - matches safety vs. uptime requirements. |
| Wide logic voltage support | 1.8 V/3.3 V/5.0 V compatible inputs allow direct interface with microcontrollers, FPGAs, and industrial PLC I/O without level shifters. |
| Charge pump + internal LDO | Generates gate drive voltage for N-channel high-side FETs and powers internal logic (DVDD = 5.0 V), simplifying power architecture. |

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 |
|---|---|---|---|
| DRV8955PWP | Same PWP package, 48 V max VM, identical pinout and logic interface; lower max voltage but same 4 A rating and IPROPI architecture. | Better suited for 24 V–48 V systems where 55 V headroom is unnecessary; shares layout compatibility and firmware interface. | Select DRV8955PWP when operating below 48 V and seeking reduced cost or qualification effort with identical footprint. |
| DRV8962DDW | 44-pin DDW package, 65 V max VM, 5 A/channel, adds VCC pin and MODE-programmable slew rate; not pin-compatible with DRV8952PWPR. | Required for higher-voltage (e.g., 60 V bus) or higher-current (>4 A) applications; supports separate logic supply and finer PWM timing control. | Choose DRV8962DDW only if 55 V margin is insufficient or 5 A per channel is mandatory - requires PCB redesign. |
Compared with DRV8952PWPR, DRV8955PWP offers identical integration and layout reuse at lower voltage, while DRV8962DDW trades pin compatibility for extended voltage/current capability and enhanced programmability - neither is drop-in, but both serve adjacent design requirements.

FAQ
What is the maximum continuous output current per channel for DRV8952PWPR?
The DRV8952PWPR supports up to 4 A continuous current per output channel under recommended operating conditions (TA ≤ 125 °C, proper PCB thermal design). This rating is validated for the PWP package and reflects thermal limits - actual current depends on ambient temperature, copper area, and airflow. The device includes overcurrent protection that trips at 7.6 A peak to safeguard against short circuits.
Does DRV8952PWPR support current regulation, and how is it configured?
Yes, DRV8952PWPR supports integrated current regulation using its VREF pin. For the PWP package, ITRIP is calculated as ITRIP = VREF / KV, where KV = 0.66 V/A. Applying a 3.3 V reference sets ~5 A trip level. Regulation uses fixed 16 µs off-time PWM chopping, and the IPROPI outputs provide real-time current feedback for closed-loop control or diagnostics.
What protection features does DRV8952PWPR include, and how are faults signaled?
DRV8952PWPR includes VM undervoltage lockout (4.23 V rising), charge pump undervoltage detection, overcurrent protection (7.6 A trip), and thermal shutdown (150 °C). All faults assert the open-drain nFAULT pin low. The OCPM pin selects fault recovery mode: latch-off (requires nSLEEP reset pulse) or auto-retry (4.1 ms interval), enabling flexible safety policy implementation in the host system.
Can DRV8952PWPR drive a stepper motor, and what configuration is required?
Yes, DRV8952PWPR can drive one bipolar 2-phase stepper motor by configuring OUT1/OUT2 as Phase A and OUT3/OUT4 as Phase B. Each pair forms a full H-bridge. PWM applied to INx pins enables slow-decay microstepping; ENx-based PWM enables fast-decay control. Current regulation via VREF ensures consistent torque across speeds, and IPROPI outputs allow stall detection and adaptive current scaling in DRV8952PWPR-based designs.
Is DRV8952PWPR pin-compatible with any other Texas Instruments drivers?
Yes, DRV8952PWPR is pin-to-pin compatible with DRV8955PWP - sharing identical 28-pin HTSSOP (PWP) footprint, pin functions, and electrical interface. This allows direct substitution in 48 V-rated systems. It is not compatible with the 44-pin DDW variants (e.g., DRV8952DDWR or DRV8962DDW), which require PCB redesign due to different pin count, layout, and added features like VCC and MODE pins.
