MAX13053ESA+

Drivers, Receivers, Transceivers Overview

The MAX13053ESA+ is a high-speed CAN transceiver in an 8-pin SO package. It supports data rates up to 1Mbps and operates on a single +5V supply (4.75V to 5.25V). The device features ±80V fault protection on bus lines, exceeding ISO11898 specifications with a common-mode range greater than ±12V. It includes silent mode for disabling the transmitter while monitoring the bus, and a reference output for biasing older controllers. Operating temperatures range from -40°C to +85°C, with standby current at 12.5mA.

Drivers, Receivers, Transceivers Feature Summary

• Silent mode disables the transmitter while maintaining bus monitoring capability
• Extended ±80V fault protection on CANH and CANL pins
• Common-mode input range exceeds ±12V for harsh environments
• Integrated reference output for biasing differential comparators

Drivers, Receivers, Transceivers Applications

• DeviceNet nodes requiring robust overvoltage protection
• Medium- and heavy-duty truck systems
• Industrial network applications with extended fault tolerance

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix against official documentation to confirm temperature grade and lead-free status. Confirm pin compatibility if replacing legacy components. Ensure ESD handling protocols are followed during assembly due to sensitive input structures.

Drivers, Receivers, Transceivers Selection Notes

Select this component when silent mode operation is required alongside standard high-speed CAN communication. Verify that the +5V logic interface matches the microcontroller system voltage. Consider thermal management if operating near maximum junction temperatures.

Drivers, Receivers, Transceivers Part Context

Part of the MAX13050/MAX13052/MAX13053/MAX13054 family sharing pin-for-pin compatibility. Designed for industrial networks needing extended fault protection beyond standard automotive or office environments.

Drivers, Receivers, Transceivers Replacement Considerations

TJA1050 and AMIS-30660 are publicly confirmed pin-compatible replacements.

Drivers, Receivers, Transceivers FAQ

How does the silent mode function differ from standby mode?

In silent mode, the transmitter is disabled regardless of the TXD input level, but the receiver continues to monitor the bus. Standby mode shuts off the transmitter and switches the receiver to a low-current state.

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

The REF pin provides a reference voltage set to 0.5 x VCC, which can be used to bias the input of older CAN controllers that utilize a differential comparator.

Does the device support dominant timeout functionality?

Yes, if the TXD input is held low for greater than 1ms, the transmitter becomes disabled and drives the bus to a recessive state to prevent bus locking.
