Description
General part information
DRV8425E Series
The DRV8424/25 are stepper motor drivers for industrial and consumer applications. The device is fully integrated with two N-channel power MOSFET H-bridge drivers, a microstepping indexer, and integrated current sensing. The DRV8424 is capable of driving up to 2.5-A full-scale output current; and the DRV8425 is capable of driving up to 2-A full-scale output current (dependent on PCB design).
The DRV8424/25 use an internal current sense architecture to eliminate the need for two external power sense resistors, saving PCB area and system cost. The devices use an internal PWM current regulation scheme selectable between smart tune, slow and mixed decay options. Smart tune automatically adjusts for optimal current regulation, compensates for motor variation and aging effects and reduces audible noise from the motor.
A simple STEP/DIR interface allows an external controller to manage the direction and step rate of the stepper motor. The device can be configured in full-step to 1/256 microstepping. A low-power sleep mode is provided using a dedicated nSLEEP pin. Protection features are provided for supply undervoltage, charge pump faults, overcurrent, short circuits, and overtemperature. Fault conditions are indicated by the nFAULT pin.
