Power Management - Specialized datasheet and documents for MAX253MSA/PR+

MAX253MSA/PR+

Power Management - Specialized Overview

The MAX253MSA/PR+ is a monolithic oscillator and power driver designed to provide isolated power for RS-485 or RS-232 data interfaces. It drives a center-tapped transformer primary from a 5V or 3.3V DC supply. The device operates with a supply voltage range of 2.5V to 6V, delivering an output current of 1A. It features non-inverting configuration, consumes 450µA operating supply current, and dissipates 727mW power. Operating temperature spans -40°C to +85°C in the SOIC-8 package.
