DRV8411A v30
Type: Adom Molecule
Creator: adom
Version: v1
Category: motor_driver
Availability: 100%, 24/7
Overview
The DRV8411A v30 molecule is a breakout of the Texas Instruments DRV8411A dual‑H‑bridge motor driver, capable of driving one bipolar stepper motor or one to two brushed DC motors with supply voltages ranging from 1.65 V to 11 V and peak currents up to 4 A. It features low ON‑resistance (~400 mΩ typical), integrated current regulation and sensing (via IPROPI outputs), support for 1.8 V/3.3 V/5 V logic inputs, and built‑in protections (undervoltage lockout, overcurrent retry, thermal shutdown). The molecule includes all required support components and breaks out the VM, H‑bridge outputs, PWM/enable inputs, fault indicator, and current‐sense pins to machine contacts for rapid integration.
