3423
MC3423 Overvoltage Crowbar Sensing Circuit This overvoltage protection circuit (OVP) protects sensitive electronic circuitry from overvoltage transients or regulator failures when used in conjunction with an external “crowbar” SCR. The device senses the overvoltage condition and quickly “crowbars” or short circuits the supply, forcing the supply into current limiting or opening the fuse or circuit breaker. The protection voltage threshold is adjustable and the MC3423 can be programmed for minimum duration of overvoltage condition before tripping, thus supplying noise immunity. The MC3423 is essentially a “two terminal” system, therefore it can be used with either positive or negative supplies. http://onsemi.com MARKING DIAGRAMS 8 PDIP−8 P1 SUFFIX PLASTIC PACKAGE CASE 626 1 MC3423P1 AWL YYWW Features • Pb−Free Package is Available MC3423P1 = Device Code A = Assembly Location WL = Wafer Lot YY = Year WW = Work Week MAXIMUM RATINGS Rating Symbol Sense Voltage (2) Unit 40 Vdc VSense1 Sense Voltage (1) Value VCC−VEE Differential Power Supply Voltage 6.5 Vdc VSense2 6.5 Vact 7.0 Vdc Output Current IO 300 Operating Ambient Temperature Range TA 0 to +70 TJ 125 °C Tstg −65 to +150 °C 3423 ALYW °C Operating Junction Temperature SOIC−8 D SUFFIX PLASTIC PACKAGE CASE 751 mA Remote Activation Input Voltage Storage Temperature Range Vdc 8 8 Maximum ratings are those values beyond which device damage can occur. Maximum ratings applied to the device are individual stress limit values (not normal operating conditions) and are not valid simultaneously. If these limits are exceeded, device functional operation is not implied, damage may occur and reliability may be affected. 1 3423 A L Y W 1 = Device Code = Assembly Location = Wafer Lot = Year = Work Week PIN CONNECTIONS Current Limited DC Power Supply Cout Drive Output 7 VEE Sense 2 3 O.
