DRV8825PWP Description

DRV8825PWP  provides an integrated motor driver solution for printer scanners and other automation equipment applications. The device has two H-bridge drivers and a micro-step divider designed to drive bipolar stepper motors. The output driver block consists of an N-channel power MOSFET configured as a full H-bridge to drive the motor winding. DRV8825 can drive up to 2.5 amperes per output (appropriate heat dissipation at 24 volts and 25 °C).The simple step / DIR interface allows easy connection to the controller circuit. The mode pin allows the motor to operate continuously in a full-step to 1-step 32-step mode. Falloff modes can be configured to use slow falloff, fast falloff, or mixed falloff. A low power sleep mode is provided, which closes the internal circuit to achieve very low static current consumption. The hibernation mode can be set using the designed nSLEEP pin.With over-current, short-circuit, under-voltage locking, high temperature and other internal shutdown functions. The fault status is indicated by the nFAULT pin.
