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:
o• rated supply voltage 5.0 V;
.c• generation of reset signal when power supply is on for
correct start of microprocessor;
U• generation 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;
e• possibility to program threashold voltage
eat which reset signal is generated.
ORDERING INFORMATION

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:
.D• generation of reset signal per fixed level of supply
wvoltage;
• generation of reset signal from external “Reset” button;
w• generation of signal of watchdog timer status;
w• emergency interruption of primary power source.
