TEXAS INSTRUMENTS DRV8881PRHRT Motor Driver, Stepper/Brushed DC, 6.5V to 45V supply, 1.4A/1 Output, WQFN-28 新
The DRV8881 is a bipolar stepper or brushed-DC motor driver for industrial applications. The device output stage consists of two N-channel power MOSFET H-bridge drivers. The DRV8881 is capable of driving up to 2.5-A peak current or 1.4-A rms current per H-bridge with proper PCB ground plane for thermal dissipation and at 24 V and TA = 25°C.
AutoTune™ automatically tunes motors for optimal current regulation performance and compensates for motor variation and aging effects. AutoTune is available on the DRV8881E. Additionally, slow, fast, and mixed decay modes are available.
The PH/EN DRV8881E or PWM DRV8881P pins provide a simple control interface. An internal sense amplifier allows for adjustable current control. 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 a nFAULT pin.
