eet4U.comMicro Monitor Supply Control
ataShThe IN1705 is designed to control power supply and to start mi-
.Dcrocontroller and microprocessor systems. It is used for securing
wstable functioning of the system when starting and halting the device
was well as in the case of the supply voltage drops.
w Manufactured in 8-pin SOIC/DIP package MS-012AA.
TECHNICAL DATA
IN1705
mLSI features:
orated supply voltage 5.0 V;
.cgeneration of reset signal when power supply is on for
correct start of microprocessor;
Ugeneration of reset signal when power supply drops below
the operating one to avoid incorrect functioning of
t4microprocessor;
generation of reset signal when pushing reset button;
epossibility to program threashold voltage
eat which reset signal is generated.
ORDERING INFORMATION
IL1705N Plastic

TA = -40° to 85° C for all packages.
ShThe IN1705 contains a source of reference voltage,
two analog comparators, watchdog timer, digital sampler,
tadigital delay..
aFunctions:
.Dgeneration of reset signal per fixed level of supply
wvoltage;
generation of reset signal from external “Reset” button;
wgeneration of signal of watchdog timer status;
wemergency interruption of primary power source.
