MAX253ESA+T Description

Short technical summary and product information.

The MAX253ESA+T is a monolithic oscillator and power-driver IC from Analog Devices / Maxim Integrated, specifically engineered to provide isolated power for RS-485 or RS-232 data interfaces. This device drives a center-tapped transformer primary from a single 5V or 3.3V DC power supply. The secondary winding can be configured to provide any required isolated voltage, supporting power levels up to 1W.

 

Key features include pin-selectable operating frequencies of 200kHz or 350kHz, and a low-current shutdown mode drawing only 0.4µA. The MAX253ESA+T is housed in an 8-SOIC package, minimizing board space. Its operating temperature range is -40°C to +85°C, making it suitable for various industrial and communication applications requiring high noise immunity and isolated power supplies.

 

This component is ideal for applications such as isolated RS-485/RS-232 power supplies, high noise-immunity communications interfaces, and bridging ground differentials. The surface-mount 8-SOIC package facilitates integration into compact designs.
