产品信息

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
