Product Summary

The MAX253CSA is a monolithic oscillator/power-driver. The device is specifically designed to provide isolated power for an isolated RS-485 or RS-232 data interface. The MAX253CSAe drives a center-tapped transformer primary from a 5V or 3.3V DC power supply. The secondary can be wound to provide any isolated voltage needed at power levels up to 1W. The applications of the MAX253CSA include Isolated RS-485/RS-232 Power-Supply, Transformer Driver, High Noise-Immunity Communications Interface, Isolated and/or High-Voltage Power Supplies, Bridge Ground Differentials, Medical Equipment and Process Control.
