TI DRV8885 A微步距步进马达驱动方案
TI DRV8885
TI公司的DRV8885是集成了电流检测的具有1/,包括两个N沟MOSFET H桥驱动器,微步距分度器和电流检测,满刻度电流精度±%,-37V,主要用在多功能打印机和扫描仪,激光打印机,3D打印机,ATM,视频安全照相机,办公自动化设备,,功能框图,应用框图,以及评估板DRV8885 EVM框图,电路图,材料清单和PCB设计图.
The DRV8885 is a stepper motor driver for industrial equipment applications. The device has two N-channel power MOSFET H-bridge drivers, a microstepping indexer, and integrated current sense. The DRV8885 is capable of driving up to A full scale or Arms output current (depending on proper PCB ground plane for thermal dissipation and at 24 V and TA = 25℃).
The DRV8885 integrated current sense functionality eliminates the need for two external sense resistors.
The STEP/DIR pins provide a simple control interface. The device can be configured in full-step up to 1/16 step modes. A low-power sleep mode is provided for very-low quiescent current standby using a dedicated nSLEEP pin.
Internal protection functions are provided for undervoltage, charge pump faults, overcurrent, short circuits, and overtemperature. Fault conditions are indicated by an nFAULT pin.
DRV8885主要特性:
PWM Microstepping Stepper Motor Driver
Up to 1/16 Microstepping
Non-Circular and Standard ? Step Modes
Integrated Current Sense Functionality
No Sense Resistors Required
±% Full-Scale Current Accuracy
Slow and
