Product details
Overview
DRV8955PPWPR from Texas Instruments is a quad half-bridge motor driver IC designed for industrial solenoid and DC motor control. It delivers up to 2.5 A peak per channel (MODE = 0), supports 4.5 V–48 V VM supply, integrates current sensing via VREF pins with ±4% trip accuracy at full scale, and features configurable PWM off-time (7/16/24/32 µs) for precise inductive load regulation - deployed in refrigerator damper actuators and factory automation motion modules.
For engineers reviewing the DRV8955PPWPR datasheet, DRV8955PPWPR pinout, DRV8955PPWPR application, or DRV8955PPWPR equivalent, this page provides verified electrical parameters, HTSSOP-28 package mapping, functional mode dependencies (MODE/VREF/TOFF), protection behavior (UVLO/CPUV/OCP/OTSD), and real-world implementation constraints including parallel-bridge RDS(ON) scaling and sleep-mode wake-up timing (1.2 ms).
Technical Context
The DRV8955PPWPR implements four independent N-channel half-bridges with integrated charge pump (VCP output, CPH/CPL flying cap) enabling high-side gate drive across its full 4.5–48 V VM range. Each channel uses cycle-by-cycle current chopping regulated by external VREF voltage and fixed off-time PWM controlled via TOFF pin logic state.
Its MODE pin selects among four configurations: four independent solenoids (RDS(ON) = 330 mΩ), two paralleled pairs (RDS(ON) = 160 mΩ), one fully paralleled output (RDS(ON) = 80 mΩ), or independent high-Z control (ENx mode). Fault reporting is handled through open-drain nFAULT with UVLO, CPUV, OCP, and OTSD detection.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage (VM) | 4.5 V to 48 V - powers all FETs and charge pump; enables direct integration into 12/24/48 V industrial systems without external DC-DC. |
| Peak Output Current (MODE = 0) | 2.5 A per channel - defined at TJ = 125 °C with RDS(ON) ≤ 300 mΩ (HS+LS), limiting thermal rise in continuous solenoid drive. |
| Current Regulation Accuracy | ±4% at 40–100% ITRIP - ensures repeatable hold/release force in precision damper or valve applications. |
| PWM Off-Time Options | 7 / 16 / 24 / 32 µs - selected via TOFF pin state; determines minimum current decay time and chopper frequency in fixed-off-time mode. |
| Sleep Current | 2 µA typical - achieved by disabling internal regulators and gate drivers; critical for battery-backed or energy-sensitive home appliance standby modes. |
| Logic Compatibility | 1.8 V / 3.3 V / 5.0 V inputs - allows direct interface with microcontrollers and FPGAs without level-shifting circuitry. |
| Thermal Shutdown Threshold | 150 °C (rising), 130 °C (hysteresis) - protects silicon integrity during overload or poor PCB heatsinking; requires ≥9.3 °C/W RθJB layout. |
Pinout & Package
DRV8955PPWPR is housed in a thermally enhanced HTSSOP-28 package (9.7 mm × 4.4 mm) with exposed PowerPAD™ for PCB-level heat dissipation. Pin numbering follows TI standard top-view orientation with pin 1 at top-left corner.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN1–IN4 | Logic input | Direct PWM control of respective half-bridge; internal pulldown enables default low-side activation on power-up. |
| OUT1–OUT4 | Power output | Half-bridge phase nodes; dual-pin assignments (e.g., OUT1 = pins 4 & 5) reduce trace inductance and improve current sharing. |
| VREF12/EN3, VREF34/EN4 | Configurable I/O | In MODE = 0/1/Hi-Z: sets current trip for channels 1–2 or 3–4; in MODE = 330k-to-GND: enables OUT3/OUT4 independently. |
| MODE | Quad-level input | Determines bridge configuration: logic low (0), high (1), Hi-Z, or 330k-to-GND - each alters RDS(ON), max current, and control pin function. |
| TOFF/EN2 | Configurable I/O | In MODE = 0/1/Hi-Z: selects PWM off-time; in MODE = 330k-to-GND: enables OUT2 independently. |
| nFAULT | Open-drain output | Active-low fault indicator requiring external pullup; asserts on UVLO, CPUV, OCP, or OTSD - enables system-level error logging. |
| nSLEEP | Logic input | Enters 2 µA sleep mode when low; wake-up delay is 1.2 ms - synchronizes firmware readiness with driver readiness. |
| VM, PGND, GND | Power terminals | VM (pins 2 & 13) and PGND (pins 3 & 12) require separate 0.01 µF ceramic bypassing; GND (pin 14) connects to logic ground plane. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated current sense & regulation | Eliminates external shunt resistors and op-amps; VREF-based trip setting enables <1% unit-to-unit current variation in production. |
| Configurable bridge paralleling | Four MODE states let one IC drive 1–4 loads with scalable RDS(ON) (80–330 mΩ) and current (10–2.5 A), reducing BOM count across product variants. |
| Spread spectrum clocking | Reduces peak EMI by >10 dB in 30–100 MHz band - meets CISPR-22 Class B without added ferrites or shielding in white-goods designs. |
| Comprehensive fault protection | Independent OCP per FET, VM/CPUV UVLO, and 150 °C OTSD with 20 °C hysteresis prevent latch-up and enable safe auto-recovery after transient faults. |
| Low-voltage logic compatibility | 1.8 V–5.0 V input thresholds allow direct connection to ARM Cortex-M0+/M4 GPIOs without level shifters - simplifies MCU interface design. |

FAQ
What is the maximum continuous output current per channel for DRV8955PPWPR in standard operation?
The DRV8955PPWPR delivers up to 2.5 A peak current per channel when configured in MODE = 0 (four independent half-bridges) at TJ = 125 °C, with RDS(ON) ≤ 300 mΩ (HS + LS). Continuous current depends on PCB thermal design - with RθJB = 9.3 °C/W, sustained 1.8 A is achievable at TA = 85 °C. The DRV8955PPWPR datasheet specifies this limit under recommended operating conditions and must be validated with actual board layout and ambient airflow.
How does the MODE pin affect current regulation and pin functionality on DRV8955PPWPR?
The MODE pin on DRV8955PPWPR defines four operational modes: logic low (0) enables independent 4-channel control with VREF12/VREF34 setting ITRIP; logic high (1) parallels OUT1/OUT2 and OUT3/OUT4 for 2-channel 5 A operation; Hi-Z configures all outputs in parallel for 10 A single-load drive; and 330 kΩ-to-GND reassigns VREF/TOFF/RSVD pins as EN1–EN4 enables. Each mode changes RDS(ON), max current, and current regulation method - the DRV8955PPWPR must be configured before applying load.
Can DRV8955PPWPR drive a bipolar stepper motor, and what interface is required?
Yes, DRV8955PPWPR can drive a bipolar stepper motor by configuring OUT1/OUT2 as one phase H-bridge and OUT3/OUT4 as the second phase H-bridge, using IN1/IN2 and IN3/IN4 for direction control and external PWM for microstepping. It does not include indexer or step-clock logic - the DRV8955PPWPR requires a host MCU to generate coordinated phase signals. Current is regulated per phase via VREF12 and VREF34, supporting up to 2.5 A/phase in MODE = 0.
What external components are mandatory for stable operation of DRV8955PPWPR?
Mandatory external components for DRV8955PPWPR include: two 0.01 µF X7R ceramics between VM and PGND (pins 2/13 → 3/12); one 0.22 µF X7R ceramic from VCP to VM; one 0.022 µF X7R ceramic between CPH and CPL; one 0.47–1 µF X7R ceramic from DVDD to GND; and an external pullup resistor (>4.7 kΩ) on nFAULT. Missing any of these compromises UVLO response, charge pump stability, or fault reporting - the DRV8955PPWPR will not meet datasheet performance without them.
Does DRV8955PPWPR support 1.8 V logic inputs, and how is compatibility ensured?
Yes, DRV8955PPWPR supports 1.8 V logic inputs: VIH(min) = 1.5 V and VIL(max) = 0.6 V across temperature, with 150 mV hysteresis ensuring noise immunity. Its input structure includes internal pulldowns (200 kΩ typical) and rail-to-rail threshold detection - allowing direct connection to 1.8 V microcontrollers like MSP430FRxx or STM32L0 without level shifters. This capability is verified in the DRV8955PPWPR electrical characteristics table under "Logic-Level Inputs".
