1 / 141 page  Preliminary Data This is preliminary information on a new product now in development or undergoing evaluation. Details are subject to change without notice. November 2007 Rev 1 1/141 1 SABRE-LL-I Combo motor driver Features ■ Configurable device ■ 4 full bridges to generate – Up 2 DC motor drivers and 1 stepper motor driver or – 4 DC motor drivers ■ Bridges (1 & 2) additional configurations are – Super DC – 2 half bridges – 1 super half bridge – 2 switches –1 super switch ■ Bridges (3 & 4) additional configurations are: – Same as bridges 1&2, listed above – 2 buck regulators (bridge 3) – 1 super buck regulator – Battery charger (bridge 4) ■ One variable voltage buck switching regulator ■ One switching regulator controller ■ One linear regulator ■ Bidirectional serial interface ■ Programmable watchdog function ■ Integrated power sequencing and supervisory functions with fault signaling through serial interface and external reset pin ■ Thermal shutdown protection with thermal warning capability ■ Very low power dissipation in shut-down mode (~35 mW) ■ Aux features – Operational amplifiers –Comparators – Pass switches – Multi-channels 9 bit ADC –GPIOs 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.
