The MAX3053 is a ±80V fault-protected CAN transceiver designed for industrial systems that require data rates up to 2Mbps. It features differential transmit and receive capability and provides ±80V fault protection against shorts to high-voltage power buses. The device has three different modes of operation: high-speed, slope control, and shutdown. It also has an autoshutdown function that puts the device in a low-current mode when the bus or CAN controller is inactive for 47ms or greater.
The MAX3053 CAN transceiver from Maxim provides differential transmit and receive capability for CAN bus systems. It offers three operating modes—high‑speed, slope‑control, and shutdown—and includes +80 V fault protection for high‑voltage environments.
The device operates from a single +5 V supply, drawing 56 mA in dominant state, 3.6 mA in recessive state, and only 15 µA in shutdown. It is supplied in an 8‑pin SO package and is rated for –40 °C to +125 °C operation, making it suitable for industrial, automotive, and HVAC applications.
| Fault protection voltage | +80 V |
|---|---|
| Maximum data rate | 2 Mbps |
| Dominant supply current | 56 mA |
| Recessive supply current | 3.6 mA |
| Shutdown supply current | 15 µA |
| Operating temperature range | -40 °C to +125 °C |
The MAX3053 can operate at up to 2 Mbps in high‑speed mode.
It supports three modes: high‑speed, slope‑control, and shutdown.
The transceiver offers +80 V fault protection (reduced to +70 V at 2 Mbps).
In shutdown mode the supply current is about 15 µA.
