​Housed in a 4 x 4 mm² LQFN package, the MAX241EWI+ is an advanced low power transceiver for signal and power line communication networks. This single-pair transceiver is designed to meet the requirements of industrial, automotive and embedded applications, such as RS-232, CAN and LIN networks. The device is ideal for applications that require high-voltage, low-power and compact size.

The MAX241EWI+ has an operating range of 1V to 4.6V, with a reception threshold range of 70mV to 1V, both adjustable by external resistors. The device features a robust data rate and power consumption that meet SAE J1939 and ISO 11898 standards. This transceiver also offers an integrated line fault protection feature to protect against reverse voltage line conditions, as well as ESD protection for up to 2kV human body model.

The MAX241EWI+ is a full-duplex transceiver, meaning that it can both transmit and receive data simultaneously. The device provides a data-flow control mechanism that can be used to break an ongoing signal flow, allowing the data receiver to take control of the data stream. This feature can be helpful in multi-bus applications, such as RS-232 networks. The device also includes a low-power shutdown mode and can be used in sleep mode for low-power applications.

The MAX241EWI+ has a 1/2 kHz baud rate limiter and utilizes a special crystal oscillator circuit to maintain a stable frequency and reduce EMI. The low-power, wide-attenuation receiver provides robust reception in noisy environments while also featuring hysteresis to eliminate false triggering. The device also features an output driver that can operate at up to 36V, allowing it to be used in many different applications.

To optimize power consumption in the MAX241EWI+, the device incorporates a low-power standby mode. The standby mode reduces the current consumption of the device by 95% when it is not in use and improves the efficiency of the overall system. This feature eliminates the need for a power switch and can also be used to reduce leakage current when the device is off.

The MAX241EWI+ is an ideal solution for applications that require low power, high-speed data transmission and reception over long distances. The device is highly reliable and offers reliable performance even in noisy environments. The wide supply voltage range makes it easy to use in different applications, from automotive to industrial, and the integrated line fault protection ensures the highest degree of safety.
