MAX3098EBEEE

MAX3098EBEEE is a low-power transceiver designed to interface between a controller and a device operating at different voltage levels in the physical layer of a communication system. Its faster slew rate, smaller package size and improved overall performance make it ideal for embedded applications that require uncompromised signals.

Application Field

The MAX3098EBEEE is designed for applications that require bidirectional communications over diverse physical-layer interfaces. It can provide data communication at speeds up to 16 Mbps in the emerging 2.5 V, 3.3 V, and 5 V environments. The transceiver is a low-power device that consumes only 1.3 mA of current and operates over the industrial temperature range without additional cooling.

The device is particularly suited for use in wearable devices such as smart watches, fitness trackers, and intelligent health monitoring systems due to its small package size, low power consumption, and excellent signal integrity. It is also ideal for medical applications that require high reliability such as glucose and other diagnostics, patient monitoring, and intraoperative imaging.

Working Principle

The MAX3098EBEEE consists of two identical full-duplex serial communication ports, each configured as either a transmitter (TX) or receiver (RX). The ports are capable of communicating with a lined interface such as RS232 or UART, or to a logic interface such as SPI or I2C. Each port consists of a separate power-on reset circuit, which allows the transceiver to reset all circuits when power is applied, and a programmable, low-power sleep mode.

The signal integrity of the MAX3098EBEEE is a result of its signal-integrity optimized, precision signal-level matching, implemented by maximized-amplitude signal switching. The low-power switching technology minimizes active power dissipation and increases system battery life. Additionally, the device integrates USB-compliant signal-drive characteristics and ESD protection for reliable operation for the most common communication interfaces.

The programmable, low-power sleep mode allows the transceiver to enter a low-power sleep state with a minimum current draw of 2.5 mA. In this state, the device can reduce its core voltage or enter a power-saving mode for further power savings. This feature is particularly useful for applications that need to remain in low-power consumption mode for extended periods of time.

In addition, the MAX3098EBEEE is equipped with a number of safety features to protect critical system components. These include an under-voltage lockout circuit, ESD protection, hot-plug protection, power-on reset, and optional over-current protection.

The MAX3098EBEEE is a low-power transceiver ideal for low-power embedded applications requiring low data rates and uncompromised signal integrity. It features advanced features such as a programmable low-power sleep mode and integrated USB-compliant signal-drive characteristics and ESD protection for reliable operation. These features make it well suited for use in wearable and medical applications.
