MAX253CPA+ Description

Short technical summary and product information.

The MAX253CPA+ 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 5V or 3.3V DC power supply, enabling the secondary to provide any isolated voltage needed for power levels up to 1W.

 

Key features include a low-current shutdown mode of 0.4µA and pin-selectable frequencies of 350kHz or 200kHz. The MAX253CPA+ is housed in an 8-pin DIP package, suitable for applications requiring high noise-immunity communications interfaces, isolated power supplies, and bridge ground differentials.

 

This component is designed for through-hole mounting and operates within a temperature range of 0°C to 70°C. Its primary application is as a transformer driver for isolated data interfaces, making it a versatile choice for various industrial and medical equipment.
