IS32IO1163B-ZLA3-TR

Overview

The IS32IO1163B-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 an independent VIO pin for 3.3V or 5V logic interfaces. The built-in LDO provides up to 100mA at 5V nominal output (±3% accuracy) with a 150mA current limit. Operating voltage ranges from 6.3V to 32V, with a wide common-mode range of ±12V. It includes ±8kV HBM ESD protection on bus pins, over-temperature shutdown, and bidirectional reset functionality in an eTSSOP-14 package.

Feature Summary

• Supports high-speed CAN FD communication up to 5Mbps
• Integrates a 5V LDO capable of supplying external circuits like MCUs
• Features ISO 11898-6 compliant low power mode with remote wakeup capability
• Provides independent VIO supply for flexible 3.3V or 5V logic interface compatibility

Applications

• Automotive networks
• Industrial networks

Procurement Notes

Verify the specific ordering suffix ZLA3-TR corresponds to the eTSSOP-14 package with lead-free compliance and a reel quantity of 2500 units. Confirm that the B variant is selected for independent VIO pin functionality rather than the A variant where VIO is internally shorted to V1. Ensure the application environment operates within the specified -40°C to +125°C temperature range and adheres to the 6.3V to 32V supply constraints.

Selection Notes

Select the IS32IO1163B variant when the system requires an independent VIO supply voltage distinct from the internal LDO output, enabling 3.3V logic interfacing. Choose this component for applications needing integrated power regulation for peripheral devices such as sensors or actuators directly from the transceiver's LDO. Consider the thermal dissipation implications if utilizing the full 100mA LDO load capacity at higher battery voltages.

Part Context

This device belongs to the IS32IO1163 family of CAN FD transceivers manufactured by Lumissil Microsystems. The family includes the IS32IO1163A variant, which differs by having its VIO pin internally connected to the V1 LDO output, restricting it to 5V I/O compatibility only. Both variants share the same core transceiver specifications, packaging, and functional capabilities.
