ST has launched an IO-Hyperlink reference design for industrial beacons and home-appliance alarms, delivered ready-to-use as a totally constructed board full with protocol stack and software software program.

The EVLIOL4LSV1 board leverages ST’s L6364Q dual-channel IO-Hyperlink transceiver to deal with communications and the IPS4260L clever low-side energy swap for driving the indicator lights. The board will be immediately linked to signaling methods comparable to sensible tower lights utilized in manufacturing facility automation, funnel materials alarms for quantity-remaining or urgency-level consciousness, and different system warnings. It additionally supplies a quick solution to take a look at the IPS4260L and L6364Q ICs and has a 4-pin M12 connector for an IO-LINK grasp and a 5-pin SWD connector for programming.

An STM32G071CB microcontroller, which hosts the ST proprietary IO-Hyperlink demo stack and the applying software program, handles system management and diagnostics, speaking with the transceiver and low-side swap.

The L6364Q transceiver is totally protected and helps standardized IO-Hyperlink communication speeds together with 38.4kbit/s COM2 and 230.4kbit/s COM3. The transceiver can function in single or multibyte mode, in addition to in clear mode delegating management of IO-Hyperlink communications to the microcontroller by a easy URT interface. The in-built safety ensures EMC immunity as much as 2.5kVpk surge pulse/500Ω coupling with out extra safety components.

The IPS4260L low-side driver has 4 outputs for driving masses with one facet linked to provide voltage, every individually managed by a sign comparable to a digital microcontroller output. It has a large operating-voltage vary, from 8V to 50V, and the present for every output will be independently programmed from 0.5A to three.0A. The IC integrates overload and overtemperature safety for every channel and supplies open-load, overload, and overtemperature diagnostic alerts to assist system administration and improve reliability. The reference design additionally options ST’s SMBJ30CA TVS (transient-voltage suppression) diode to resist surge pulses with 2Ω coupling on the availability rail.
