MAX13053ESA+T

Drivers, Receivers, Transceivers Overview

The MAX13053ESA+T is a high-speed CAN transceiver from the MAX1305x family, designed for industrial networks requiring extended overvoltage protection. It operates on a single +5V supply and supports data rates up to 1Mbps. The device features ±80V fault protection on bus lines and ±8kV ESD protection per IEC 61000-4-2. Key functional attributes include a silent mode that disables the transmitter while maintaining receiver monitoring, and a reference output (REF) set to 0.5 x VCC for biasing older CAN controllers. It includes a dominant timeout function to prevent bus clamping and operates within a temperature range of -40°C to +85°C in an 8-pin SO package.

Drivers, Receivers, Transceivers Feature Summary

• Silent Mode Operation: Disables the transmitter upon logic-high input at the S pin while allowing continuous monitoring of the bus via the RXD output.
• Extended Fault Protection: Provides ±80V fault tolerance on CANH and CANL pins, exceeding standard specifications for harsh industrial environments.
• Reference Output: Includes a dedicated REF pin providing a stable voltage level (0.5 x VCC) suitable for biasing differential comparators in legacy CAN controllers.
• Dominant Timeout Function: Automatically disables the transmitter if the TXD input remains low for longer than 1ms, preventing erroneous bus locking.

Drivers, Receivers, Transceivers Applications

• DeviceNet nodes requiring robust overvoltage protection
• Medium- and heavy-duty truck systems
• Industrial control networks with legacy controller interfaces

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'ESA+T' against official manufacturer documentation to confirm the tape-and-reel packaging format and lead-free status. Ensure the component meets RoHS compliance requirements for your assembly process. Cross-reference the ordering information table in the datasheet to validate the package code and temperature grade associated with this specific part number before procurement.

Drivers, Receivers, Transceivers Selection Notes

Select the MAX13053ESA+T when silent mode operation is required to isolate the transmitter without affecting bus reception. This variant is appropriate for applications needing a reference voltage output to interface with older CAN controllers lacking internal biasing. It is distinct from the MAX13050/MAX13052 which offer common-mode stabilization, and the MAX13054 which supports separate 3.3V logic supplies.

Drivers, Receivers, Transceivers Part Context

This component belongs to the MAX13050/MAX13052/MAX13053/MAX13054 family of industry-standard high-speed CAN transceivers. These devices are pin-for-pin compatible, sharing the same 8-pin SO footprint and basic electrical characteristics, while differing in specific features like slope control, silent mode, or dual-supply logic compatibility.

Drivers, Receivers, Transceivers Replacement Considerations

Publicly confirmed substitutes listed in the datasheet selector guide include TJA1050 and AMIS-30660 for the MAX13053 variant. Verify pinout compatibility and feature equivalence, particularly regarding the silent mode and reference output functionality, before substitution.

Drivers, Receivers, Transceivers FAQ

How does the silent mode function on the MAX13053?

Driving the S pin high places the device in silent mode, which disables the transmitter regardless of the TXD input state. The receiver remains active, allowing the RXD output to continue monitoring bus activity.

What is the purpose of the REF pin on the MAX13053?

The REF pin provides a fixed output voltage equal to 0.5 x VCC. It is designed to bias the input of older CAN controllers that utilize a differential comparator, ensuring proper signal interpretation.

What happens if the TXD input is held low for more than 1ms?

The dominant timeout function activates, disabling the transmitter and driving the bus lines to a recessive state. This prevents a hung microcontroller from clamping the bus permanently.
