    產品信息

    The AMIS-30422 is a micro-stepping stepper motor bridge controller for large current range bipolar applications. The chip interfaces via a SPI interface with an external controller in order to control two external power NMOS H-bridges. It has an on-chip voltage regulator, current sensing, self adapting PWM controller and pre-driver with smart slope control switching allowing the part to be EMC compliant with industrial and automotive applications. It uses a proprietary PWM algorithm for reliable current control.
    • Dual H-bridge pre-drivers for two phase stepper motors
    • Programmable current via SPI
    • On-chip current translator
    • SPI interface
    • Speed and load angle output
    • 9 step modes from full step up to 128 microsteps
    • Current sense via two external sense resistors
    • PWM current control with automatic selection of fast and slow decay
    • Low EMC PWM with selectable voltage slopes
    • Full output protection and diagnosis
    • Thermal warning and shutdown
    • Compatible with 3.3 V microcontrollers
    • Integrated 3.3 V regulator to supply external microcontroller
    • Integrated reset function to reset external microcontroller
    • Integrated watchdog function
