TECHNICAL DATA
Micro Monitor Supply Control
IN1705
The IN1705 is designed to control power supply and to start mi-
crocontroller and microprocessor systems. It is used for securing sta-
ble functioning of the system when starting and halting the device as
well as in the case of the supply voltage drops.
Manufactured in 8-pin SOIC/DIP package MS-012AA.
LSI features:
rated supply voltage 5.0 V;
generation of reset signal when power supply is on for
correct start of microprocessor;
generation of reset signal when power supply drops below
the operating one to avoid incorrect functioning of
microprocessor;
generation of reset signal when pushing reset button;
possibility to program threashold voltage
at which reset signal is generated.
ORDERING INFORMATION
IL1705N Plastic
IL1705D SOIC
TA = -40° to 85° C for all packages.
The IN1705 contains a source of reference voltage,
two analog comparators, watchdog timer, digital sampler,
digital delay.
Functions:
generation of reset signal per fixed level of supply
voltage;
generation of reset signal from external “Reset” button;
generation of signal of watchdog timer status;
emergency interruption of primary power source.

Exposure to absolute maximum rating conditions may affect reliability of IC and its functional operation.
Upon removing the absolute maximum ratings conditions, functional operation is guaranteed in recommended operating
conditions.
* Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device.
These are stress ratings only and functional operation of the device at these or any other conditions beyond those indi-
cated under “recommended operating conditions” is not implied.
Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
