IS32IO1163A-ZLA3-TR

Overview

The IS32IO1163A-ZLA3-TR is a CAN FD bus transceiver integrated with a 5V LDO, compliant with ISO 11898-2/5 and supporting ISO 11898-6 low power mode. It supports data rates up to 5Mbps and features a built-in LDO supplying up to 100mA for external loads like MCUs or sensors. The device operates on a battery voltage range of 6.3V to 32V and includes ±8kV HBM ESD protection on CANH/CANL pins. It utilizes an eTSSOP-14 package with an exposed pad and is AEC-Q100 qualified.

Feature Summary

• Integrated 5V LDO capable of supplying up to 100mA for external circuits
• Supports high-speed CAN FD communication up to 5Mbps
• Includes ISO 11898-6 low power mode with remote wakeup capability
• Features bidirectional reset pin and optimized EME/EMI performance

Applications

• Automotive networks
• Industrial networks

Procurement Notes

Verify the specific suffix 'A' indicates internal connection between VIO and V1, distinguishing it from the 'B' variant which offers independent VIO control. Confirm the eTSSOP-14 package dimensions and exposed pad thermal requirements match the design layout. Ensure compliance with AEC-Q100 qualification standards for automotive deployment.

Selection Notes

Select this component when a CAN FD transceiver with integrated power regulation is required. The IS32IO1163A variant is suitable for systems where the I/O logic supply can share the LDO output. Consider the 6.3V to 32V input range and 5V nominal LDO output accuracy of +/- 3% for system power budgeting.

Part Context

This part belongs to the Lumissil IS32IO series of CAN FD transceivers. It is designed for robust communication in electrically noisy environments typical of automotive and industrial settings. The integration of the LDO reduces component count by eliminating the need for a separate regulator for the MCU or sensor interface.

Replacement Considerations

The IS32IO1163B-ZLA3-TR is a compatible alternative within the same family, offering an independent VIO pin for 3.3V IO compatibility instead of the internally shorted VIO found in the IS32IO1163A.
