NCP112

NCP112 Supervisory IC for Desktop Power Supply Monitoring The NCP112 is a highly integrated supervisory circuit that incorporates all the functions necessary for monitoring and controlling a multi−output switch−mode power supply system. The NCP112 provides an ability to monitor the status of the power supply outputs and communicate it to the system controller. The programmable output delays protect against spurious fault indicators. Features Under and Overvoltage Protection for 3.3 V, 5.0 V and 12 V Outputs Additional Adjustable Overvoltage Protection Input Built−in Hysteresis on all Input Pins Programmable Undervoltage Blanking During Power−Up Fault Output with 20 mA Sink Capability Programmable Remote On/Off Delay Time Programmable Power Good Delay Time Precision Voltage Reference with 20 mA Source Capability Optimized for Low−Cost 100 nF Capacitors Enhanced Replacement to the TSM112 This is a Pb−Free Device Typical Applications Personal Computer Switch Mode Power Supply Monitoring Multi−Output Power Supplies Requiring System Supervision http://onsemi.com MARKING DIAGRAMS 14 1 SOIC−14 D SUFFIX CASE 751A NCP112DG AWLYWW 1 14 1 PDIP−14 P SUFFIX CASE 646 NCP112P AWLYYWWG 1 A = Assembly Location WL = Wafer Lot Y, YY = Year WW = Work Week G = Pb−Free Package PIN CONNECTIONS VS33 VS5 VS12 ADJ PGI CTUV GND VCC FAULT PGO CTPG CTREMOTE REMOTE VREF PDIP−14, SOIC−14 ORDERING INFORMATION See detailed ordering and shipping information in the ...
