The MAX253CPA+ Gate Drivers Transformer Driver for Iso RS-485 Int is a highly reliable integrated circuit from Analog Devices, designed to provide precision control of RS-485/RS-422 transceivers. It features an automatic transmit data rate of up to 250kbps, and can drive up to two VBUS-type transformers, each providing up to 600mA for bus-powered applications. The MAX253CPA+ is also designed for protection against ESD, over-voltage, short-circuits, and other common fault conditions. It includes a wide variety of features such as thermal shutdown, power-saving modes, and noise immunity. It is intended for use in applications where the required data rate and robustness are critical, such as in mobile communications, industrial automation, and other critical communications systems.
