DRV8256PPWPR

DRV8256PPWPR is Texas Instruments’ dual motor-driver IC. It provides two full-bridge (H-bridge) outputs for driving two DC motors or one two‑phase stepper, controlled via simple logic inputs and PWM. It integrates the power MOSFETs and supports current regulation (set via an external sense resistor) for smooth torque and protection.
Key features (high level):
- Two independent bridge channels for bidirectional motor control
- PWM speed/torque control with constant-current regulation
- Protective features: undervoltage, overcurrent, overtemperature, fault/diagnostic reporting
- Enable/sleep and fault reporting outputs for easy MCU integration
- Suitable for robotics, fans, actuators, and other compact motor-drive applications
- Package variant PPWPR indicates a specific TI packaging finish/size
For exact electrical specs, pinout, recommended operating conditions, and application circuits, see the DRV8256 datasheet and TI product page.

Here are the key features of the DRV8256PPWPR:
- Dual full-bridge motor driver for stepper and DC motors
- Integrated high-side/low-side FETs for two motor windings
- Adjustable current limit via a single reference resistor (per bridge)
- PWM current regulation with selectable decay modes
- Step and direction control interface with enable/sleep/fault pins
- Wide supply voltage range (suitable for 8–50 V systems)
- High-current capability with proper cooling
- Protective features: overcurrent, overtemperature, undervoltage/UVLO
- Fault/status reporting outputs for fault indication
- Soft-start and controlled current decay to reduce motor noise
- Small, TI PPWPR package suitable for compact boards
Note: exact electrical specs (current, decay options, voltage range) depend on the specific variant and application, so consult the datasheet for precise values.

- Pin count: 28 pins (PWPR package; HTSSOP/TSSOP-28 style).
- Function: Dual DMOS H‑bridge motor driver. Provides two independent high/low‑side outputs to drive two motors (or a two‑phase stepper). Includes current regulation (Vref), protection features (overcurrent/UVLO/thermal), and a fault/diagnostic output; logic inputs control each bridge (enable, direction/pwm as applicable).

- Manufacturer: Texas Instruments Incorporated (TI).
- Company type: American multinational semiconductor company that designs and manufactures analog and embedded processing integrated circuits (including motor drivers, microcontrollers, sensors, etc.).

DRV8256PPWPR is a dual full-bridge motor driver with PWM current regulation. Useful for driving two DC motors or one bipolar stepper motor. Common application areas:
