MAX13412EESA+

Drivers, Receivers, Transceivers Overview

The MAX13412EESA+ is a half-duplex RS-485 transceiver featuring an internal low-dropout regulator and proprietary AutoDirection control. It operates from a supply voltage range of +6V to +28V, with the internal LDO generating a stable +5V output capable of sourcing up to 20mA for external circuitry. The device supports data rates up to 500kbps with slew-rate limiting to minimize EMI. It includes enhanced ±15kV Human Body Model ESD protection on the A and B pins, fail-safe receiver circuitry, and thermal shutdown at +150°C. Packaged in an 8-pin SOIC with an exposed paddle, it functions reliably across an extended temperature range of -40°C to +85°C.

Drivers, Receivers, Transceivers Feature Summary

• AutoDirection control architecture eliminates the need for separate driver enable and receiver output enable signals.
• Integrated low-dropout regulator allows operation from unregulated power supplies up to 28V.
• Enhanced electrostatic discharge protection rated at ±15kV on the differential bus lines.

Drivers, Receivers, Transceivers Applications

• Isolated RS-485 communication interfaces
• Utility metering systems
• Industrial equipment networking

Drivers, Receivers, Transceivers Procurement Notes

Verify component authenticity through authorized distribution channels or direct manufacturer engagement. Confirm package markings match the specific ordering suffix and ensure compliance with current RoHS directives. Cross-reference datasheet revisions to validate pin configurations and electrical characteristics against the intended design requirements.

Drivers, Receivers, Transceivers Selection Notes

Select this variant when system isolation requires reduced optical isolator count due to automatic direction control. Ensure the application utilizes a supply voltage between 6V and 28V to leverage the integrated LDO. Verify that the 500kbps maximum data rate meets network timing constraints and that the exposed pad thermal dissipation capabilities are sufficient for the operating environment.

Drivers, Receivers, Transceivers Part Context

This component belongs to the MAX13410E–MAX13415E family of isolated RS-485 transceivers. Unlike the MAX13410E, which lacks AutoDirection, this model integrates automatic driver and receiver switching logic. It shares the same 8-pin SO-EP footprint as other family members but differs functionally by providing the VREG output and eliminating discrete control signal dependencies.

Drivers, Receivers, Transceivers Replacement Considerations

The MAX13413E serves as a full-speed alternative within the same family, supporting data rates up to 16Mbps without slew-rate limiting. Both devices share identical pinouts and AutoDirection functionality, facilitating direct substitution where higher transmission speeds are required.
