IS32IO1028A-GRLA2-TR

Overview

The IS32IO1028A-GRLA2-TR is a LIN bus transceiver with an integrated LDO, compliant with LIN 2.0 through 2.2A and SAE J2602-2 standards. It operates on a battery voltage (VBAT) range of 6V to 30V, supporting data rates up to 20kBaud with slope control for secure communication. The device includes a built-in 5V LDO capable of supplying up to 100mA to external components. It features multiple operational modes including Normal, Standby, and Sleep to minimize current consumption. The component is housed in an eSOP-8 package with an exposed pad and is qualified under AEC-Q100 standards.

Feature Summary

• Compliant with LIN 2.X/SAE J2602 specifications
• Integrated LDO output for external component supply
• Supports sleep mode and local wakeup from EN pin
• TXD dominant time out function prevents bus locking

Applications

• Automotive networking
• Industrial networking
• Convenience electronics slave nodes

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm the exact LDO output voltage configuration. The datasheet lists IS32IO1028A as the 5V option and IS32IO1028B as the 3.3V option. Ensure the requested part number matches the required voltage level for your application design before finalizing procurement.

Selection Notes

Select this component when designing simple LIN slave nodes that require an integrated power regulator. The choice between the A and B variants depends strictly on whether a 5V or 3.3V LDO output is needed for the connected microcontroller. Consider the thermal characteristics and the exposed pad requirement for proper heat dissipation in the SOP-8 package layout.

Part Context

This transceiver belongs to the IS32IO1028 family designed for low-speed vehicle data communication. It integrates physical layer transmission with power regulation to simplify circuit designs. The device supports both remote and local wakeup mechanisms, making it suitable for applications requiring efficient power management in automotive and industrial environments.

Replacement Considerations

The IS32IO1028B-GRLA3-TR serves as a functional alternative if a 3.3V LDO output is required instead of the 5V version. Verify compatibility regarding the operating temperature range and package dimensions before substitution.
