Description
General part information
DRV8434A Series
The DRV8434A is a stepper motor driver 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 DRV8434A is capable of driving up to 2.5 A full-scale output current (dependent on PCB thermal design).
The DRV8434A uses an internal current sense architecture to eliminate the need for two external power sense resistors, saving PCB area and system cost. The device uses an internal PWM current regulation scheme with smart tune ripple control decay. 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.
