NJU2103AD

NJU2103A System Reset IC ■FEATURES ■GENERAL DESCRIPTION ・Full compatible with NJM2103 ・Detection Voltage VSA=4.2V±1.0% ・Adjustable Detection Voltage VSB=1.22V±1.0% ・VSA and VSB have Hysteresis Characteristics at Reset release ・Possible to detect Over Voltage VSC=1.235V±1.0% ・Operating Temperature Ta=-40 to 125°C ・Low Quiescent Current 280µA typ. ・Reference Voltage can be taken out ・Low reset operation voltage 0.8V typ. ・Package DMP8, DIP8, TVSP8 ■APPLICATION The NJU2103A is a power supply voltage monitoring IC that instantaneously detects abnormality such as power supply voltage cutoff or drop and generates reset signal. It can monitor 2 systems of 5 V power supply and arbitrarily set voltage. It is possible to direct replacement from NJM2103 and the small TVSP8 package is added. Furthermore, it improves usability by extending operating temperature, standardizing AC characteristics, and making each parameter highly accurate. ■TYPICAL APPLICATION ・Industrial equipment ・Housing and facility equipment ・OA equipment ・Amusement equipment ■BLOCK DIAGRAM Ver.1.2 www.njr.com -1- NJU2103A ■PIN CONFIGURATION DMP8/DIP8/TVSP8 (Top View) PIN No. PIN NAME 1 CT 2 3 VSC OUTC 4 5 6 7 8 GND + V VSB/RESIN VSA RESET FUNCTION Connects Capacitor pin for setting RESET Output Pulse Width Comparator C input pin Comparator C output pin GND pin Power Supply pin Comparator B input pin Comparator A input pin RESET output pin (Active Low) ■PRODUCT NAME INFORMATION NJU2103A M (TE1) Device Package Name M:DMP8 Taping form D: DIP8 RB1:TVSP8 ■ORDERING INFORMATION PRODUCT NAME PACKAGE OUTLINE RoHS HalogenFree TERMINAL FINISH MARKING WEIGHT (mg) MOQ (pcs) NJU2103AM(TE1) DMP8 ○ ○ Sn-2Bi 2103A 95 2000 NJU2103AD DIP8 TVSP8 ○ ○ ○ Sn-2Bi Sn-2Bi 2103AD 2103A 510 18 2000 2000 NJU2103ARB1(TE1) Ver.1.2 www.njr.com -2- NJU2103A ■ABSOLUTE MAXIMUM RATINGS PARAMETER Supply Voltage SYMBOL + RATINGS UNIT -0.3 to 20 + -0.3 to V +0.3 (
