The MAX1406CAE+ from Maxim Integrated is a high-performance, low-power, RS-232 and V.28/V.24 communications interface with automatic shutdown/wakeup features and high data-rate capabilities. This integrated circuit is designed to meet the stringent requirements of battery-powered applications such as portable devices, while also being suitable for desktop and industrial solutions.

Key Features

• Integrated Charge Pump Circuitry: The device includes onboard charge pump circuitry that generates the necessary RS-232 voltage levels (+/-10V) from a single 3.0V to 5.5V supply, eliminating the need for multiple power sources.
• High Data Rate: Capable of data rates up to 120kbps, the MAX1406CAE+ is suitable for high-speed data communication in complex systems.
• Low Power Consumption: Its power-saving features make it ideal for battery-operated devices, with a low-power shutdown mode that reduces power consumption to just 1µA, ensuring extended battery life.
• Electrostatic Discharge (ESD) Protection: The device offers built-in ESD protection up to ±15kV, using the Human Body Model (HBM), which provides robustness against electrical disturbances.
• Automatic Shutdown and Wakeup: The MAX1406CAE+ automatically enters a low-power shutdown mode when the RS-232 cable is disconnected or when the connected peripherals are turned off, and it can be configured to wake up upon detecting activity.

Applications

The MAX1406CAE+ is versatile and can be used in a variety of applications, including:

• Portable and battery-powered devices
• Notebook and laptop computers
• Handheld equipment
• Industrial and medical equipment
