TECHNICAL DATA
Micro Monitor Supply Control
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.
IN1705
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.
