The MAX253EPA 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, enabling the secondary to provide any isolated voltage needed at power levels up to 1W.
Key electrical specifications include a supply voltage range of 3.3V to 5V and a typical supply current of 450µA. It features pin-selectable frequencies of 200kHz or 350kHz and a low-current shutdown mode with a typical current of 0.4µA.
This device is housed in an 8-pin DIP package, suitable for through-hole mounting. The operating temperature range is -40°C to +85°C, making it suitable for industrial and commercial applications. Its design simplifies power-supply transformer driver configurations for isolated communication interfaces.
Applications include isolated RS-485/RS-232 power supplies, high noise-immunity communications interfaces, isolated and/or high-voltage power supplies, bridge ground differentials, medical equipment, and process control.
