Texas Instruments DRV8849 | Demoboard DRV8849EVM
Dual stepper driver with integrated current sense, STEP/DIR Interface and smart tune technology EVM
Overview
| Topology | Motor Drive |
| Input voltage | 35 V |
| Output 1 | 1.5 A |
| IC revision | A |
Description
The DRV8849 is a dual stepper motor driver for industrial and consumer applications. The device is fully integrated with four N-channel power MOSFET H-bridge drivers, one microstepping indexer for each stepper, and integrated current sensing. The DRV8849 is capable of driving up to 1.5-A (limited by board design). The DRV8849 uses STEP/DIR interface to control the direction and step rate of the stepper motor.Protection features are provided for supply undervoltage, charge pump faults, overcurrent, short circuits, and overtemperature. and 38 V. This driver offers Smart tune decay mode for smooth and quiet operation. Protection features in this driver include thermal shutdown with hysteresis (OTSD), undervoltage lockout (UVLO) and overcurrent protection (OCP).
Features
