Digital Isolators are used in a wide variety of applications, ranging from automation and communications to medical and industrial. The MAX14932EAWE+T is a fully isolated, low power, bidirectional digital isolator with a wide operating temperature range, making it ideal for a number of industrial, medical and automotive applications.

The MAX14932EAWE+T is a monolithic CMOS-based digital isolator that provides galvanic isolation between its transfer inputs and outputs. It offers 500V rms galvanic isolation, low power consumption of 10mW and a wide operating temperature range from -55°C to 125°C. It is designed to operate from input logic levels as low as 0.3V and are immune to latch-up due to their integral silicone diode and clamping networks.

The MAX14932EAWE+T offers the best performance--in terms of power consumption, size, and isolation--for low-power industrial applications, such as fieldbus communications, motion control, and data logging. It provides galvanic isolation for:

• Transferring digital signals from one system to another with a difference of potential;
• Transferring analog signals from one system to another;
• Transferring high-voltage signals from one system to another;
• Transmitting signals through circuits with unpredictable noise;
• Reducing the electro-magnetic interference among devices.

The MAX14932EAWE+T digital isolator works by utilizing an integrated circuit design that includes two independent drivers, two independent receivers and a gate driver. The receivers detect and convert the input signal into an internal logic signal, while the drivers convert the internal logic signal into the output signal. This design enables the isolator to handle large voltage swings, while also providing an extremely low-power consumption and a wide operating temperature range.

The MAX14932EAWE+T digital isolator can achieve data rates of up to 12Mbps. The isolator is also immune to input over-voltage transients and ESD to meet stringent industrial standards. The isolation also includes common-mode transient immunity (CMTI) and differential-mode transient immunity (DMTI). It features a low power and low-swing differential receiver and has inrush-current limiting and short-circuit protection.

The MAX14932EAWE+T is an ideal solution for industrial, medical and automotive applications that require low-power bidirectional digital isolation. The isolator is highly reliable and provides a high level of EMI/RFI noise immunity, which is critical for transferring data between two systems. It is also capable of transmitting signals through circuits with unpredictable levels of noise, allowing for greater accuracy and reliability in data communication.
