Description
SABRe is a new concept of IC in the Motion & Power Supply field. ST aim is to follow the SABRe 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.
