EVAL6470H-DISC: fully integrated stepper motor driver based on the L6470 and STM32™ User manual
■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 L6470 fully integrated solution suitable for driving two-phase bipolar stepper motors up to 1/128 microstepping.
■The L6470 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.
●Main features
■The characteristics of the EVAL6470H-DISC board are the following:
▲DC voltage range from 8 V to 45 V
▲Maximum load phase current at 3 Ar.m.s.
▲Footprint for external resonator or crystal
▲Control interface through trimmer - user keys and switch motor input
▲Control through LED indicators
▲Interface control by USB and debug outputs
▲Compatible with SPINFamily evaluation tool
▲Autonomous board due to an embedded firmware
▲Up to 1/128 microstepping
▲Optimized layout on 2-layer board - low cost and high thermal performance
