TECHNICAL DATA
KIA7419P/F~KIA7445P/F
BIPOLAR LINEAR INTEGRATED CIRCUIT
VOLTAGE DETECTOR
This IC series is usable for the CPU system of all types and wired
logic system as it has the function of detecting the power supply voltage
at the time of initial resetting after switching the power supply on and
after instantaneous break in power supply voltage there-by accurately
resetting the system this particular series has especially been designed
as the high resetting output type.
FEATURES
Current Consumption is Low. ICCL=30 A Typ.
ICCH=300 A Typ.
Resetting Output Minimum Guarantee Voltage is Low 0.8V Typ.
Hysteresis Voltage is Provided 50mV Typ.
Reset Signal Generation Starting Voltages:
KIA7419P/F 1.9V Typ. KIA7433P/F 3.3V Typ.
KIA7421P/F 2.1V Typ. KIA7434P/F 3.4V Typ.
KIA7423P/F 2.3V Typ. KIA7435P/F 3.5V Typ.
KIA7425P/F 2.5V Typ. KIA7436P/F 3.6V Typ.
KIA7427P/F 2.7V Typ. KIA7439P/F 3.9V Typ.
KIA7429P/F 2.9V Typ. KIA7442P/F 4.2V Typ.
KIA7431P/F 3.1V Typ. KIA7445P/F 4.5V Typ.
KIA7432P/F 3.2V Typ.
Taping Type is also Available.
APPLICATIONS
(1) As Control Circuit of Battery-Backed Memory Units.
(2) As Measure Against Erroneous Operations at Power Supply ON-OFF Time.
(3) As Measure Against System Runaway at Instantaneous Break of Power
Supply etc.
(4) As Resetting Function for the CPU-Mounted Equipment, such as Personal
Computers, Printers, VTRs and so forth.
