The AMIS-30543 is a micro-stepping stepper motor driver for bipolar stepper motors from ON Semiconductor. It connects to an external microcontroller via I/O pins and an SPI interface. The device features an on-chip voltage regulator, reset output, and watchdog reset, capable of supplying peripheral devices.
Key specifications include a programmable peak current up to 3A, an on-chip current translator, and eleven step modes ranging from full step up to 128 micro-steps. It utilizes a proprietary PWM algorithm for reliable current control with automatic selection of fast and slow decay, and low EMC PWM with selectable voltage slopes. The driver operates within a voltage range of 6V to 30V and has an operating temperature range of -40°C to 172°C (TJ).
Implemented in I2T100 technology, the AMIS-30543 integrates high-voltage analog circuitry and digital functionality on a single chip. It is fully compatible with automotive voltage requirements and is well-suited for general-purpose stepper motor applications in automotive, industrial, medical, and marine environments. The on-chip voltage regulator helps reduce the Bill of Materials (BOM) for mechatronic stepper applications.
This IC is available in a 32-QFN (7x7) package with surface mount mounting type. It provides full output protection and diagnosis, along with thermal warning and shutdown capabilities. It is compatible with 5V and 3.3V microcontrollers.
