Description
S.A.B.Re™ (structured architecture of bridges
and regulators) is a new concept of IC in the
motion & power supply field. ST aim is to follow
the S.A.B.Re specification and to offer to the
customer an IC with a wide number of features,
that can be configured and customized: motor
drivers, regulators, high precision A/D converter,
operational amplifiers and voltage comparators.
The start up configuration can be defined by the
GPIOs and then through the serial interface; a
customization can be done through a metal layer
in order to set more complex functions.
