Description

The L6482, 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 full-bridge gate driver for N-

channel MOSFET power stages with embedded

non-dissipative overcurrent protection. Thanks to

a new current control, a 1/16 microstepping is

achieved through an adaptive decay mode which

outperforms traditional implementations. The

digital control core can generate user defined

motion profiles with acceleration, deceleration,

speed or target position easily programmed

through a dedicated register set. All application

commands and data registers, including those

used to set analog values (i.e. 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 and motor stall) make the L6482

“bullet proof”, as required by the most demanding

motor control applications.
