| NTE15044 Integrated Circuit CMOS, LSI for Supply Voltage Detection Description: The NTE15044 is an integrated circuit in a 3-Lead DIP type package which generates a reset signal for initializing microcomputers and LSI systems at their power-on time, and a reset signal for preventing an abnormal system run at power fluctuation time. Features: D Generates a Reset Signal at Power-On Time Until Reaching a Constant Voltage D Generates a Reset Signal Below a Constant Voltage at Power-Off Time D Generates a Reset Signal when the Supply Voltage Falls, and Cancels it when the Supply Voltage is Restored D Capable of Detecting a Battery Service Life D 3-Pin Adjustment-Free Device D High-Accuracy Voltage Detection D Low Power Consumption: 10A Typ @ VDD = 5V Absolute Maximum Ratings: (VSS = 0, TA = +25C unless otherwise specified) Supply Voltage, VDD . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 7V Output Voltage, VO . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . -0.3 to VDD +0.3V Operating Ambient Temperature, Topr . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . -20 to +70C Storage Temperature Range, Tstg . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . -55 to +125C Recommended Operating Conditions: (VSS = 0, TA = +25C unless otherwise specified) Parameter Supply Voltage Symbol VDD Test Conditions Min 2 Typ - Max 6 Unit V DC Electrical Characteristics: (VSS = 0, TA = -20 to +70C unless otherwise specified) Parameter Supply Current Detected Voltage Hysteresis Width Detected Voltage at Supply Voltage Fall Output Voltage High Level Output Voltage Low Level Symbol IDD VDL VD VOH VOL Test Conditions VDD = 5V at no-load output TA = +25C TA = +25C IOH = -40A IOL = 0.7mA, VDD = 3V Min - 4.0 100 0.8 VDD VSS Typ 10 - 200 - - Max 30 4.3 300 VDD 0.4 Unit A V mV V V AC Electrical Characteristics: Parameter Reset Cancel Time Reset Time Symbol tOH tOL Test Conditions Min - - Typ 5 5 Max - - Unit s s .271 (6.9) .098 (2.5) .137 (3.5) Out VDD VSS .039 (1.0) .039 (1.0) .177 (4.5) .122 (3.1) .161 (4.1) .098 (2.5) |
