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. It drives a center-tapped transformer primary using a 5V or 3.3V DC power supply, enabling the secondary to provide any required isolated voltage up to 1W.
Key features include pin-selectable frequencies of 200kHz or 350kHz, and a low-current shutdown mode consuming only 0.4µA. The device is housed in an 8-pin PDIP package, minimizing board space.
This transformer driver is suitable for applications requiring isolated power supplies, such as high noise-immunity communications interfaces, bridge ground differentials, medical equipment, and process control systems. Its design simplifies the creation of isolated power supply solutions for data interfaces.
The MAX253CPA operates within a temperature range of 0°C to 70°C and is mounted via a through-hole configuration.
