Контроллеры и драйверы двигателей / движения / зажигания DRV8884PWPR

Привод двигателя , шаговый, 8В до 37В питание, 700мА/1 выход, HTSSOP-24

The DRV8884PWPR is a 1A stepper motor driver with integrated current sense in 24 pin HTSSOP package. The DRV8884 device 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 DRV8884 is capable of driving up to 1A full scale or 0.7A rms output current. The DRV8884 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.
