Description

The L6470, realized in analog mixed signal

technology, is an advanced fully integrated

solution suitable for driving two-phase bipolar

stepper motors with microstepping. It integrates a

dual low RDS(on) 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. Thanks to a unique control system, a

true 1/128 steps resolution is achieved. The

digital control core can generate user defined

motion profiles with acceleration, deceleration,

speed or target position, easily programmed

through a dedicated registers set. All commands

and data registers, including those used to set

analogue values (i.e. current control value,

current protection trip point, deadtime, PWM

frequency, etc.) are sent through a standard 5-

Mbit/s SPI. A very rich set of protections (thermal,

low bus voltage, overcurrent, motor stall) allows

the design of a fully protected application, as

required by the most demanding motor control

applications.
