MAX3098EAEEE

Overview

The MAX3098EAEEE is a triple RS-422/RS-485 receiver featuring fault-detection circuitry and independent fault-status outputs. It operates on a single +3V to +5.5V supply with a maximum data rate of 32Mbps. The device provides ±15kV ESD protection via Human Body Model and IEC 1000-4-2 Air-Gap Discharge methods, alongside ±8kV Contact Discharge protection. It detects open-circuit, short-circuit, low differential voltage, and common-mode range violations. The part includes a capacitor-programmable delay for the ALARMD output to prevent erroneous alarms at slow edge rates. It is housed in a 16-pin QSOP package and supports an operating temperature range from -40°C to +85°C.

Feature Summary

• Detects open-circuit conditions, short-circuit conditions, low differential voltage signals, and common-mode range violations.
• Provides robust electrostatic discharge (ESD) protection rated up to ±15kV using Human Body Model and IEC 1000-4-2 standards.
• Features a capacitor-programmable delay on the ALARMD output to ensure error-free operation during slow data transitions.
• Offers independent universal fault outputs for each receiver channel alongside a general delayed fault indication.

Applications

• Motor-shaft encoder receivers
• Telecommunications systems
• Embedded systems

Procurement Notes

Verify the specific ordering suffix EAEEE corresponds to the -40°C to +85°C temperature range and 16-pin QSOP package configuration. Confirm that the component meets RoHS compliance requirements as specified in the manufacturer's documentation. Ensure compatibility with system voltage levels between 3V and 5.5V before integration.

Selection Notes

Select this component when high-speed signal reception up to 32Mbps is required alongside comprehensive fault monitoring capabilities. The integrated fault detection simplifies system diagnostics by identifying wiring issues such as shorts or opens without external logic. Consider the 16-pin QSOP footprint if space constraints exist relative to standard industry solutions.

FAQ

How is the delay time for the ALARMD output configured?

The delay time is set by connecting a single external capacitor from the DELAY pin to GND. The duration depends on the supply voltage and capacitance value, calculable via provided equations or graphs.

What types of faults can the MAX3098EAEEE detect?

It detects open-circuit conditions, short-circuit conditions, low differential input voltage signals, and receiver inputs exceeding the common-mode voltage range.

Does the device require pull-up resistors for the fault outputs?

No, the fault outputs are active push-pull and do not require external pull-up resistors.
