Overview

Micro Monitor ee Supply Control The IN1705 is designed to control power supply and to start microcontroller and microprocessor systems.
It is used for securing stable 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.
