ZIOL2411BI1W

Overview

The ZIOL2411BI1W is a dual-channel IO-Link high-voltage line driver IC manufactured by Renesas Electronics. It serves as the physical layer interface for sensor and actuator systems in factory automation, supporting the IO-Link communication standard. The device features two independent HV I/O channels with push-pull output stages that achieve an RDSon of less than 3.3Ω in tandem mode across all operational temperatures. It operates on a supply voltage range of 8V to 36V and includes an integrated SPI interface for accessing configuration and status registers. Configuration data is stored in on-chip EEPROM, which loads automatically during power-up.

Feature Summary

• Dual independent high-voltage I/O channels designed for IO-Link physical layer implementation
• Push-pull output drivers with low on-resistance in tandem mode for efficient signal transmission
• On-chip EEPROM storage for configuration settings with automatic loading at power-up
• Integrated SPI interface for register access and real-time status monitoring including overload and over-temperature conditions

Applications

• Factory automation sensor networks
• Actuator system interfaces
• IO-Link master transceiver implementations

Procurement Notes

Verify the specific suffix 'BI1W' against the manufacturer's official documentation to confirm package type and tape-and-reel specifications. Ensure compatibility with the required operating temperature range and supply voltage constraints before integration. Cross-reference the part number with authorized distributors to confirm current availability and lead times, as manufacturing cycles may vary.

Selection Notes

Select this component when designing IO-Link compliant systems requiring dual-channel high-voltage driving capabilities. It is suitable for applications needing configurable system features and robust status reporting via SPI. Consider the PQFN-24 package dimensions and thermal dissipation requirements relative to the 2.6W power dissipation rating. Ensure the host microcontroller supports the necessary SPI interface for configuration management.

Part Context

The ZIOL2411 belongs to Renesas' ZIOL2411 series of sensor interface ICs. This family addresses the physical layer requirements for industrial sensing and control applications. The device complements other interface solutions like the ZIOL2401, offering enhanced channel count and specific driver characteristics tailored for complex IO-Link topologies in automated environments.

Replacement Considerations

The ZIOL2401BI1W is a related single-channel variant within the same product family. Verify pinout compatibility and channel requirements before substitution, as the ZIOL2411 provides two independent channels compared to the single channel of the ZIOL2401.
