Abstract

A power IC is described with an EEPROM programmable trim for precision regulation of two switch-mode regulators and a high accuracy oscillator. In-the-package voltage adjustment to 1% and an oscillator trim of 1.5% are achieved with the internal trim capability. The IC also features an “H” bridge for DC motor control and eight low-side drivers for driving unipolar stepper motors. A modified 44 pin plastic leaded chip carrier gives 30°C/W performance
