Description
General part information
AMIS-30421 Series
The AMIS30421 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.
