Présentation
Description
The TI DRV8424PWPR is a dual H-bridge motor driver for brushed DC motors. It provides two DMOS full-bridge outputs that can drive two motors or a single axis with PWM current regulation. An external sense resistor sets the current limit via a reference voltage, enabling efficient current chopping to control torque. The device includes protections: undervoltage lockout, overcurrent, overtemperature, and over/under-voltage, plus fault reporting. Each channel has simple logic inputs to enable/disable and drive the bridges, with configurable decay modes. The PWPR package refers to a PowerPAD-enabled, RoHS-compliant package with good thermal performance. Common uses include robotics, printers, and CNC equipment needing a compact, protected dual-motor driver. For exact electrical specs, pinout, and wiring, see the DRV8424 datasheet and application notes from TI.
Features
Key features of DRV8424PWPR (TI):
- Dual full-bridge motor driver with integrated power MOSFETs (drives two DC motors or a two-phase stepper).
- Wide operating supply: 8–45 V, suitable for a range of motors.
