The MAX253CUA+T is a monolithic oscillator and power-driver IC specifically 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 power supply, allowing the secondary to provide any isolated voltage needed at power levels up to 1W.
This device features a low-current shutdown mode and pin-selectable frequencies. It is available in an 8-pin package, minimizing board space. The MAX253CUA+T is suitable for applications requiring high noise-immunity communications interfaces, isolated power supplies, and bridge ground differentials.
Key electrical characteristics include a supply voltage range of 3.3V to 5V and a typical supply current of 450µA. The operating temperature range is from 0°C to 70°C. The IC is supplied in an 8-uMAX/uSOP package and is designed for surface mount applications.
Applications include isolated RS-485/RS-232 power supplies, transformer drivers, high noise-immunity communications interfaces, isolated and/or high-voltage power supplies, bridge ground differentials, medical equipment, and process control.
