AMIS30422C422MNTWG Description

Short technical summary and product information.

The AMIS-30422 is a micro-stepping stepper motor bridge controller designed for bipolar applications. It interfaces with an external controller via SPI to manage two external power NMOS H-bridges.

 

Key features include an on-chip voltage regulator, current sensing, and a self-adapting PWM controller. It supports 9 step modes, from full step up to 128 micro-steps, and offers programmable current control via SPI. The device provides a Speed and Load Angle output, enabling stall detection algorithms and load angle-based control loops for torque and speed adjustment.

 

This controller is implemented in a mature technology, ensuring fast high-voltage analog circuitry and multiple digital functionalities on a single chip. It is fully compatible with automotive voltage requirements and is suitable for large current stepper motor applications in automotive, industrial, medical, and marine environments. The integrated voltage regulator helps reduce the Bill of Materials (BOM) for mechatronic stepper applications.

 

The AMIS30422C422MNTWG is available in a 48-QFN (7x7) package and is designed for surface mounting. It operates within a voltage range of 3V to 3.6V and has an operating temperature range of -40°C to 125°C (TJ).
