Overview

Description
The MAX253 is a monolithic oscillator/power-driver designed for isolated power supply in RS-485 or RS-232 data interfaces. It drives a center-tapped transformer primary from a 5V or 3.3V DC power supply, providing isolated voltage up to 1W. The device consists of a CMOS oscillator driving N-channel power switches, ensuring 50% duty cycle and break-before-make action. The SD pin enables a low-power shutdown mode, disabling both power switches and the oscillator.

Features
Simple power-supply transformer driver design for isolated RS-485/RS-232 data interfaces
Single 5V or 3.3V supply
Low-current shutdown mode (0.4μA)
Pin-selectable frequency (350kHz or 200kHz)
Compact 8-pin DIP, SO, and μMAX packages

Applications
Isolated RS-485/RS-232 power supply
Transformer driver
High noise-immunity communications interface
Isolated and/or high-voltage power supplies
Bridge ground differentials
Medical equipment
Process control
