MAXIM INTEGRATED / ANALOG DEVICES MAX253EPA Transformer Driver

The MAX253EPA+ is a transformer driver in an 8-pin DIP package designed for isolated RS-485 and RS-232 communication interfaces. It functions as a monolithic oscillator and power driver, providing isolated power by driving a center-tapped transformer primary from a 3.3V or 5V DC supply. The secondary winding can be configured to provide any needed isolated voltage at power levels up to 1 watt. The device includes a CMOS oscillator that activates a pair of N-channel power switches with a 50% duty cycle, ensuring proper isolation and break-before-make switching. It features a shutdown pin to disable the device, reducing power consumption to 0.4µA. Suitable for high noise-immunity communication systems, isolated and high-voltage power supplies, and bridging ground differences, the MAX253EPA+ operates with supply voltages from 2.5V to 6V and temperatures from -40°C to 85°C. Its switches have a maximum on-resistance of 4 ohms, and the device consumes up to 5mA during operation. It offers selectable switching frequencies of 200kHz or 350kHz and is ideal for applications such as medical equipment, process control, and communication networks.
