Voltage detectors BD45XXXG BD46XXXG 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 Every kind of appliances with microcontroller and logic circuit Features 1) Built-in delay time circuit 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: 0.85µA typ. 7) Output circuit: Nch open drain(BD45XXXG) CMOS(BD46XXXG) 8) Package: SSOP5(SMP5C2) 9) Operating temperature range: -40°C ~ +105°C Application Circuit BD45XXXG VDD VDD VDD BD45XXXG BD46XXXG 5 4 1pin : External RESET control 2pin : Connect to Sub, GND 3pin : GND 4pin : VOUT 5pin : VDD (Fixed delay time by the built-in ±10% of high-accuracy counter timer) 1 2 3 2.9±0.2 (5) (4) 2.8±0.2 0.2 1.6 + –0.1 (UNIT:mm) (1) (2) (3) 1.25MAX 1.1± 0.05±0.05 0.05 0.95 0.05 0.42 + –0.04 0.1 SSOP5(SMP5C2) BD46XXXG VDD VDD Vout Oscillation circuit counter timer Reset Oscillation circuit counter timer 0.2MIN 0.13 +0.05 –0.03 Vout Reset Vref Vref GND ER GND ER Pin No. SSOP5 1 ER 2 Sub 3 GND 4 VOUT 5 VDD 1/4 Voltage detectors Absolute Maximum Ratings (Ta=25˚C) 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 BD45XXXG BD46XXXG Symbol 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 Unit V V V Parameter ∗1 Derating: 5.4mW/˚C for operation above Ta=25˚C.(Mounted on a 70.0mmX70.0mmX16mm glass epoxy PCB.) mW ˚C ˚C Electrical characteristics (Unless otherwise noted; Ta=-25˚C ~ +105˚C) Detection voltage temperature coefficient Hysteresis voltage Circuit current when ON Parameter Symbol ∗1 ∗1 Min. — Typ. ±100 Max. ±360 Unit % µA µA V mA mA µA V V V µA Conditions RL=470KΩ, VDD=L→H→L VDET=2.3~3.1V VDD=VDET–0.2V VDET=3.2~4.2V VDET=4.3~4.8V VDET=2.3~3.1V VDET=3.2~4.2V VDD=VDET+2V VDET=4.3~4.8V RL=470kΩ, VOL≥0.4V VDS=0.5V, VDD=1.2V VDS=0.5V, VDD=2.4V (VDET≥2.7V) VDS=0.5V, VDD=4.8V VDET=2.3~4.2V VDS=0.5V, VDD=6.0V VDET=4.3~4.8V VDD=VDS=10V BD45XX5G, BD46XX5G RL=100kΩ BD45XX1G, BD46XX1G CL=100pF BD45XX2G, BD46XX2G VER=2.0V VDET/∆T ppm/˚C Ta=-40˚C ~ +105˚C ∗1 Circu.
