BD45XXXG BD46XXXG Voltage detectors VOLTAGE DETECTOR IC with counter timer BD45XXXG BD46XXXG BD45XXXG and BD46XXXG are series of high-accuracy detection voltage and low current consumption VOLTAGE DETECTOR ICs adopting CMOS process. New lineup of 156 types with delay time circuit have developed. Delay time is fixed in the IC due to the built-in counter timer to require no external capacitor. Total 156 types of VOLTAGE DETECTOR ICs including BD45XXXG series (Nch open drain output) and BD46XXXG series (CMOS output), each of which has 26 kinds in every 0.1V step (2.3~4.8V) and three kinds of delay time (50msec, 100msec, 200msec) have developed. Applications BD45XXXG BD46XXXG Every kind of appliances with microcontroller and logic circuit 5 Features 1) Built-in delay time circuit 1 (Fixed delay time by the built-in 10% of high-accuracy counter timer) 2) No external capacitor for setting delay time required 3) 3 kinds of delay time: 50msec(Typ.)(BD45XX5G,BD46XX5G) 100msec(Typ.)(BD45XX1G,BD46XX1G) 200msec(Typ.)(BD45XX2G,BD46XX2G) 4) Detection voltage: 2.3V ~ 4.8V 0.1V step 5) High-accuracy detection voltage: 1.0% 6) Ultra low current consumption: 0.85A typ. 7) Output circuit: Nch open drain(BD45XXXG) CMOS(BD46XXXG) 8) Package: SSOP5(SMP5C2) 9) Operating temperature range: -40C ~ +105C 2 4 3 1pin : External RESET control 2pin : Connect to Sub, GND 3pin : GND 4pin : VOUT 5pin : VDD (UNIT:mm) 0.2MIN 2.80.2 0.2 1.6 + -0.1 2.90.2 (5) (4) 1.25MAX 1.1 0.050.05 0.05 (1) (2) (3) 0.95 0.13 +0.05 -0.03 0.05 0.42 + -0.04 0.1 SSOP5(SMP5C2) Application Circuit BD45XXXG BD46XXXG VDD VDD VDD VDD VDD Vout Reset Oscillation circuit counter timer Oscillation circuit counter timer Vref Vout Reset Vref GND ER GND Pin No. 1 2 3 4 5 SSOP5 ER Sub GND VOUT VDD ER 1/4 BD45XXXG BD46XXXG Voltage detectors Absolute Maximum Ratings (Ta=25C) Limits - 0.3 ~ + 10 GND - 0.3 ~ + 10 GND - 0.3 ~ VDD + 0.3 GND - 0.3 ~ VDD + 0.3 540 - 40 ~ + 105 - 55 ~ + 125 Symbol Parameter Power supply voltage VDD - GND Output Nch open drain output VOUT voltage CMOS output ER pin input voltage VCT Power dissipation:SSOP5 1 Pd Operating temperature range Topr Tstg Storage temperature range Unit V V V mW C C 1 Derating: 5.4mW/C for operation above Ta=25C.(Mounted on a 70.0mmX70.0mmX16mm glass epoxy PCB.)
