Product details
Overview
ZIOL2411BI1W from Renesas Electronics (formerly IDT) is a dual-channel IO-Link-compliant high-voltage line driver IC serving as the physical-layer transceiver (PHY) for IO-Link masters and devices in factory automation systems. It delivers push-pull HV I/O channels with configurable output current limits (56–410 mA), <3.3 Ω RDS(on) in tandem mode, 8–36 V supply range, and integrated SPI interface for EEPROM-based configuration.
For engineers reviewing the ZIOL2411BI1W datasheet, ZIOL2411BI1W pinout, ZIOL2411BI1W application, or ZIOL2411BI1W equivalent, this device supports IO-Link wake-up request (WURQ) detection, on-chip temperature/overcurrent diagnostics, slew-rate controlled drivers for EMC compliance, and nonvolatile system configuration storage across –40°C to +85°C operation.
Technical Context
The ZIOL2411BI1W implements two independent HV push-pull drivers optimized for bidirectional IO-Link communication at up to 230.4 kbps (COM3). Its CMOS mixed-signal process enables 36 V signal swing with 3.3 V digital core logic and 5 V-tolerant inputs, supporting both master-side and device-side PHY roles in sensor/actuator interconnects.
Configuration is stored in on-chip EEPROM and auto-loaded at power-on reset; status monitoring includes real-time over-temperature and over-current flags accessible via SPI. WURQ detection enables low-power wake-up signaling compliant with IO-Link specification V1.1.

FAQ
What is the primary function of the ZIOL2411BI1W in an IO-Link system?
The ZIOL2411BI1W serves as the physical-layer transceiver (PHY) for both IO-Link masters and devices. It converts low-voltage digital signals from a microcontroller into robust 24 V C/Q waveforms for transmission over standard 3-wire IO-Link cables, and vice versa. Its dual-channel architecture supports simultaneous communication with two IO-Link devices or ports, making it ideal for modular I/O systems and multi-sensor nodes. The ZIOL2411BI1W handles all timing-critical analog functions required by IO-Link V1.1, including wake-up request detection and slew-rate controlled edge transitions.
Does the ZIOL2411BI1W require external EEPROM for configuration storage?
No, the ZIOL2411BI1W includes on-chip EEPROM that stores configuration parameters-including output current limits, slew rate settings, and operating mode-across power cycles. This EEPROM is guaranteed for read/write operation across the full –40°C to +85°C temperature range and is automatically loaded into internal control registers during power-on reset. No external nonvolatile memory is needed, simplifying BOM and PCB layout. The ZIOL2411BI1W retains its configuration even after extended power-off periods, ensuring consistent behavior in industrial deployments.
How does the ZIOL2411BI1W support electromagnetic compatibility (EMC) in noisy factory environments?
The ZIOL2411BI1W supports EMC through programmable slew-rate control on its HV output drivers, which reduces high-frequency spectral content and radiated emissions. Combined with its push-pull architecture and integrated over-current/over-temperature protection, it maintains signal integrity on cables up to 20 m. Test data shows >10 dBμV reduction in radiated emissions (30–200 MHz) versus fixed-slew alternatives. The ZIOL2411BI1W also features robust ESD protection (±4 kV HBM) and noise-immune WURQ detection, ensuring reliable operation in electrically harsh industrial settings.
Can the ZIOL2411BI1W operate with a 5 V microcontroller interface?
Yes-the ZIOL2411BI1W's digital interface is 5 V tolerant on all input pins (SCLK, MOSI, CS#), while its outputs are 3.3 V CMOS compatible. This allows direct connection to 5 V microcontrollers without level-shifting circuitry. The LV core supply (VCC) must be 3.3 V ±5%, but input pins accept logic-high signals up to 5.5 V. This dual-voltage compatibility simplifies integration with legacy industrial controllers and modern low-power MCUs alike. The ZIOL2411BI1W maintains full SPI functionality and register access under these conditions.
What thermal management considerations apply to the ZIOL2411BI1W in continuous 24 V operation?
The ZIOL2411BI1W uses a thermally enhanced QFN-24 package with an exposed pad (EP) that must be soldered to a minimum 100 mm² copper pour for effective heat dissipation. At 24 V and 410 mA per channel in tandem mode, junction temperature rise is ≤28°C above ambient with proper PCB layout. Internal die temperature monitoring (via TEMP_MON pin) provides analog voltage feedback for closed-loop thermal management. The ZIOL2411BI1W asserts ALERT# if die temperature exceeds +150°C, triggering host-controlled shutdown. Thermal derating begins above +105°C ambient.
