The MAX253CUA is a monolithic oscillator and power-driver IC from Analog Devices, specifically engineered 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, enabling the secondary to provide any isolated voltage up to 1W.
Key electrical specifications include a typical supply current of 450µA and a low-current shutdown mode of 0.4µA. The device supports pin-selectable frequencies of 350kHz or 200kHz. It operates within a temperature range of 0°C to 70°C.
The MAX253CUA is housed in an 8-pin µMAX package, suitable for applications requiring minimal board space. Its design facilitates simple power-supply transformer driver configurations for high noise-immunity communications interfaces, isolated power supplies, and bridge ground differentials.
This component is ideal for applications in medical equipment and process control where robust and isolated communication is essential.
