The MAX253EUA+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. It drives a center-tapped transformer primary from a single 5V or 3.3V DC power supply, allowing the secondary to be wound for any isolated voltage up to 1W.
This device features a CMOS oscillator driving a pair of N-channel power switches with a 50% duty cycle. It includes a low-current shutdown mode, consuming only 0.4µA. The operating temperature range is -40°C to 85°C, and it has a typical operating current of 450µA.
The MAX253EUA+T is available in an 8-pin uMAX package, suitable for surface mount applications. Its design simplifies the creation of isolated power supplies for high noise-immunity communication interfaces, bridge ground differentials, medical equipment, and process control systems.
