STEVAL-IFP010V1 Demonstration board for the VNI2140J dual high-side, solid-state smart power relay Data Brief Features Output current: 1 A per channel Shorted load protection Junction over-temperature protection Case over-temperature protection for thermal independence of the channels Non-simultaneous TCSD (thermal case shutdown) restart for the various channels Protection against loss of ground Current limitation Under-voltage shutdown Open load in OFF state and short to VCC detection STEVAL-IFP010V1 Open drain diagnostic outputs In cases where more than one channel is in 3.3 V CMOS/TTL compatible inputs overload, the TCSD restart will not be Fast demagnetization of inductive loads simultaneous, in order to prevent high peak current from the supply. Non overloaded channels Conforms to IEC 61131-2 supply voltage: +4 V continue to operate normally. The open drain to +36 V diagnostics output indicates over-temperature. Description This demonstration board is based on the VNI2140J, a monolithic device designed using ST s 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 OFF and back ON automatically in order to 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.
