EVAL6470H-DISC: Stepper, 3A/Phase @ 8 ~ 45V
Summary
The EVAL6470H-DISC can be used together with the STM32™ firmware library V1.0 and constitutes a complete motor control evaluation and a development platform.
It is a demonstration board for motor control applications in the range of 8 V to 45 V of DC bus voltage using the STM32F105RB microcontroller with an internal 128 kB Flash size and a 64 kB internal RAM and the L6470H fully integrated solution suitable for driving two-phase bipolar stepper motors up to 1/128 microstepping.
The L6470H integrates a dual DMOS full bridge with all of the power switches equipped with an accurate on-chip current sensing circuitry suitable for non-dissipative current control and overcurrent protection.
With dedicated hardware evaluation features, the EVAL6470H-DISC board is designed to help developers evaluate the device and develop their own applications.
