The MAX3083CSD+ is a single transceiver designed to operate from a single, +3.3V supply voltage. It is designed to interface with a microcontroller or other high-speed logic with TTL or CMOS inputs, while providing support for the CAN protocol and CAN-FD protocol with the high data rate capability of up to 5 Mbps. The MAX3083CSD+ is a half-duplex device, meaning it can only transmit or receive traffic but not both simultaneously.

The MAX3083CSD+ is a member of Maxim\'s CAN/CAN FD Interface IC family that includes bus transceivers and transceivers, receivers and transceivers, isolators, and bridges. Manufactured and packaged in a low-power, small footprint 3.2 mm x 3.2 mm QFN16 package, the MAX3083CSD+ is perfect for applications where board real estate is at a premium. The MAX3083CSD+ is a low-power and low-EMI solution for CAN, CAN FD, and limited-speed CAN applications.

When selecting the MAX3083CSD+ for an application, some of its benefits include:

• Low power : -40°C to +85°C ambient operation and up to 5 Mbps data transmission rate
• Low electromagnetic interference (EMI) thanks to its integrated 0.1µF bypass capacitor
• Quiet mode in which the transceiver can be completely disabled while still remaining in the bus
• Protection against current surges and short-circuits
• Low latency transmit and receive due to programmable dead time
• Resilient to short-circuiting or ground loop conditions
• Advanced error detection and signaling

The MAX3083CSD+ is designed to interface with a microcontroller or other high-speed logic with TTL or CMOS inputs, providing support for the CAN protocol and the high data rate capability of up to 5 Mbps. The primary function of the MAX3083CSD+ is to provide protection to the microcontroller and/or host processor from abnormal conditions on the CAN/CAN FD bus. The device is designed to protect against electrical fault conditions such as: node-level short-circuit, ground-short fault, bus wire shorts, bus offer, and electrical surges that may be generated from either the power supply or from transient events.

The MAX3083CSD+ features On-Chip ESD protection with three independent ESD protection circuits to protect the TXDI, RXDI, and TBC pins. Additionally, the device includes two separate UV (Under Voltage) protection circuits. The device is packaged in a small footprint 3.2mmx3.2mm QFN16 package and is designed to operate over an extended temperature range of -40°C to + 85°C.

The MAX3083CSD+ features several built-in diagnosis features that allow the bus manager (microcontroller or host processor) to determine the current health of the bus and take corrective actions when needed. These features include: Error Passivation (EP) and Error Mask (EM). The EP feature allows the system to detect and passivate any observed error on the bus, protecting the system from further damage. The EM feature allows the system to keep errors on the bus transparent, thus allowing the system to maintain a normal operation.

The MAX3083CSD+ is designed to support the CAN FD protocol, making it an ideal choice for applications where fast data rates are required. The device features programmable and configurable thresholds for baud rate and frame length. The device also features a programmable data rate of up to 5 Mbps, allowing for a flexible data rate selection and Bus arbitration. The device also offers an integrated ESD protection circuit for txd, rxd, and tbc pins, as well as a CPU Enable Pin and an integrated 0.1µF bypass capacitor for improved EMI performance.

In summary, the MAX3083CSD+ is a single transceiver designed to provide an interface between a microcontroller or other high-speed logic with TTL or CMOS inputs and a CAN/CAN FD bus. Its low power, low-EMI, and high data rate features make it an ideal choice for applications where board real estate is at a premium and fast data rates are required. Its built-in protection and diagnostics ensure reliable operation in any environment.
