SEMICONDUCTOR
TECHNICAL DATA
VOLTAGE SUPERVISOR WITH DELAY TIME
CONTROL IC. [1.25V 50mV]
Function of this IC is accurately resetting the system after detecting
voltage with delay time control application at the time of switching
power on and instantaneous power on and instantaneous power off in
various CPU systems and other logic systems.
FEATURES
Few External Components.
Current Consumption is Low : (ICCH=360 A Typ.).
Resetting Output Minimum Guarantee Voltage is Low : (0.6V Typ.).
Large Delay Time Can Generate Only by Adding a Small Capacitor.
(at 0.33 F, td 100mS)
Wide Operating Supply Voltage Range : (VCC=2 17V).
Hysteresis Voltage is Provided : (15mV Typ.).
Reset Signal Generation Sensing Voltage : (1.25V 50mV).
APPLICATIONS
As System Control Circuit Against Erroneous Operations at Power ON-OFF.
As Control Circuit of Battery-Backed Memory, Battery Indicator, Level
Detector, Waveform Shapper, Delayed Waveform Generator, DC-DC
Convertor, Over Voltage Protector, and So forth.
As Resetting Function for the CPU, MCU, PCH, NCH, CMOS and Logic.
