The ON Semiconductor evaluation board is a dual stepper motor driver evaluation board that evaluates the AMIS30543, has a micro-stepping driver. It has an on-chip voltage regulator and reset output. This chip is connected through IO pins and an SPI interface with an external microcontroller that is regulated through the PCA9655E's 16 bits of general-purpose parallel input and output (GPIO) expansion. It is applicable for stepper motor driver.
Features and Benefits:
• 128 micro steps • Active fly back diodes • Integrated power and watchdog support for an external MCU • Programmable peak current up to 3A • Programmable PWM voltage slopes • Speed and load angle output
For products that are Customized and under Non-cancellable & Non-returnable, Sales & Conditions apply.
