用于外部 FET 的步进电机驱动器/控制器

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 adapt • Dual H-bridge pre-drivers for two phase stepper motors\n• Programmable current via SPI\n• On-chip current translator\n• SPI interface\n• Speed and load angle output\n• 9 step modes from full step up to 128 microsteps\n• Current sense via two external sense resistors\n• PWM current control with aut;
