Product Brief ISOFACE™ Galvanic Isolated 8-Channel High-Side Switch with 10-fold Diagnostics The ISO2H823V establishes a new standard in diagnostics for industrial control applications. For example, in industrial plants with capital intensive single-tool equipment at work or with time critical chemical processes running, obtaining in real-time differentiated feedback from the factory floor enables both, preventive maintenance and drastic reduction of the time to fix a problem. This is why the ISO2H823V is a highly desirable system solution. System designers benefit from the ISO2H823V through short time to market, reduced PCB area and uncompromised product reliability. Application Examples Programmable Logic Controllers (PLCs) Distributed Control Systems Robotics General Control Equipment The ISO2H823V integrates Robust 2.5kV galvanic isolation –– UL508 and CSA C22.2 No. 14 certified –– To protect the 3.3V control domain of an industrial control system from the harsh 24V process side –– Exceeding the IEC 61131-2 requirements for reinforced isolation 8-channel high-side power-switching capabilities –– Of up to 0.6A per channel –– With active current limitation and overtemperature protection 10-fold diagnostic feedback –– 5 types of feedback which are available individually for each of the eight outputs –– 5 types of IC-level feedback The ISO2H823V enables product designs which meet the stringent EMI requirements of the IEC 61131-2 norm (zone C) applicable for Programmable Logical Controllers (PLC). www.infineon.com/isoface Customer benefit of ISO2H823V with 10-fold diagnostics Preventive Maintenance Failure Localization Optimizing Equipment Uptimes Product Brief ISOFACE™ Galvanic Isolated 8-Channel High-Side Switch with 10-fold Diagnostics ISO2H823V Key Feature Overview Vbb operational range Max. continuous load current per channel 0.6A Load current increase by using outputs in parallel Switch ü Inductive claming energy per output µC Interface Diagnostics on per Channel-Level 150mJ ü Open load with output „on“ ü Open load with output „off“ ü Output shorted to Vcc ü optional Overtemperature at output ü SPI or parallel optional Vbb monitoring: 3 stages ü Overtemperature of package ü Incandescent bulb detection ü Communication integrity check ü All outputs in fact off ü 3.3V Isolation voltage (UL 508) Diagnostics on IC-level VISO = 2.5kV Creepage and clearance distances 3.5mm Active output current limitation per channel 1A (nom.)
