DescriptionThis demonstration board is based on the STs VIPower technology for driving two independent resistive or inductive loads with one side connected to ground. Active current limitation prevents the dropping of system power supply in case of a shorted load. Built-in thermal shutdown protects the chip from over-temperature and short-circuit. In overload condition, channel turns maintain the junction temperature between TTSD and TR. If this condition causes case temperature to reach TCSD, the overloaded channel is turned OFF and will restart only when case temperature has decreased down to TCR.In cases where more than one channel is in overload, the TCSD restart will not be current from the supply. Non overloaded channels continue to operate normally. The open drain diagnostics output indicates over-temperature.STEVAL-IFP010V1www.st.comBoard schematicSTEVAL-IFP010V12/6 1 Board schematicFigure 1.Schematic diagramC1 10nF C2 10nF C3 100nF + C4 47uF T2 GND OUT1OUT2+24Vdc 12 M2M.2VITEB Features Output current: 1 A per channelShorted load protectionJunction over-temperature protectionCase over-temperature protection for thermal Non-simultaneous TCSD (thermal case shutdown) restart for the various channelsProtection against loss of groundCurrent limitationUnder-voltage shutdownOpen load in OFF state and short to VCC Open drain diagnostic outputs3.3 V CMOS/TTL compatible inputsFast demagnetization of inductive loadsConforms to IEC 61131-2 supply voltage: +4 V to +36 V DescriptionThis demonstration board is based on the STs VIPower technology for driving two independent resistive or inductive loads with one side connected to ground.
