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.
