STEVAL-IFP010V2 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 overtemperature protection ■ Case overtemperature 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 ■ Open drain diagnostic outputs ■ 3.3 V CMOS/TTL compatible inputs ■ Fast demagnetization of inductive loads ■ Conforms to IEC 61131-2 supply voltage: +4 V to +36 V ) s ( ct ) s ( ct u d o r P e t e l o bs STEVAL-IFP010V2 -O in order to prevent high peak current from the supply, if more than one channel is in an overload condition the TCSD restart will not be simultaneous. Non overloaded channels continue to operate normally. The open drain diagnostics output indicates an overtemperature condition. u d o r P e Description The STEVAL-IFP010V2 demonstration board is based on the VNI2140J dual high-side smart power solid-state relay. The VNI2140J is a monolithic device designed using ST’s VIPower technology to drive two independent resistive or inductive loads with one side connected to ground. Active current limitation prevents a drop in system power supply in the event of a shorted load. Built-in thermal shutdown protects the chip from overtemperature and short-circuits. In overload condition, the overloaded channel automatically turns OFF and ON to maintain the junction temperature between TTSD and TR. If this condition causes the case temperature to reach TCSD, the overloaded channel is turned OFF and will restart only when the case temperature has decreased down to TCR. t e l o s b O April 2009 Rev 1 For further information contact your local STMicroelectronics sales office. 1/5 www.st.com 5 VDD STAT2 STAT1 IN2 IN1 STAT2 IN1 VDD IN2 R7 10K 1206 R8 10K 1206 1K 1206 R6 R5 1K 1206 2 4 6 8 10 12 14 16 18 20 22 24 26 28 30 32 34 IC3 TLP281F IC4 TLP281F 1 1 2 4 3 IC5 TLP281F 2 3 4 2 3 4 1 4 3 2 1 STAT1 IC2 TLP281F EVALCOMMBOARD J1 1 3 5 7 9 11 13 15 17 19 21 23 25 27 29 31 33 10K 1206 R10 10K 1206 47K 1206 47K 1206 R9 R3 R4 T6 T5 T4 T3 2 3 5 6 7 Diag 1 Diag 2 In 2 In 1 Vcc 12 STAT1 VDD IN1 A B 2/5 Vcc s b O t e l o TAB P e Vcc d o r J4 2 4 6 8 10 12 14 GND DISC.
