ADM3062EBCPZ

Overview

The ADM3062EBCPZ is a half-duplex RS-485 transceiver manufactured by Analog Devices Inc. It operates with a VCC supply range of 3.0 V to 5.5 V and features a separate VIO logic supply pin supporting 1.62 V to 5.5 V. The device supports a maximum data rate of 500 kbps and provides IEC 61000-4-2 ESD protection rated at ±12 kV for both contact and air discharge. It utilizes a 10-lead, 3 mm × 3 mm LFCSP package and functions within an extended temperature range from -40°C to +125°C.

Feature Summary

• IEC 61000-4-2 Level 4 electrostatic discharge protection on bus pins
• Flexible digital interface via independent VIO logic supply pin
• Full hot swap support ensuring glitch-free power-up and power-down
• Receiver fail-safe for short-circuit, open circuit, and bus idle conditions

Applications

• Industrial fieldbuses
• Process control systems
• Building automation networks
• PROFIBUS networks
• Motor control servo drives and encoders

Procurement Notes

Verify the specific ordering suffix against official documentation to confirm package type and temperature grade. Confirm that the required VIO voltage level matches the target logic interface. Ensure thermal design accounts for the specified junction-to-ambient resistance in the chosen package configuration.

Selection Notes

Select this model when a half-duplex RS-485 interface is required with high ESD immunity. The dedicated VIO pin allows compatibility with low-voltage logic controllers down to 1.62 V. Choose this variant over non-E models if robust protection against industrial electrical noise is necessary.

Part Context

This component belongs to the ADM306xE family of RS-485 transceivers designed for multipoint communication. It shares core architectural features with other members like the ADM3061E and ADM3063E but is distinct in its duplex mode and inclusion of the VIO pin for flexible logic interfacing.

Replacement Considerations

Direct functional replacements within the same family include the ADM3066E series for higher speed requirements, provided the package and VIO capabilities align with the system design constraints.

FAQ

Does the ADM3062EBCPZ support full-duplex operation?

No, the ADM3062E is a half-duplex transceiver. Full-duplex options in this family are designated as ADM3063E or ADM3064E.

What is the purpose of the VIO pin?

The VIO pin provides a separate logic supply input, allowing the digital interface to operate independently of the main VCC supply, with a minimum voltage of 1.62 V.

Is the device compliant with PROFIBUS standards?

Yes, the device is PROFIBUS compliant when the VCC supply is greater than or equal to 4.5 V.
