TECHNICAL DATA Micro Monitor 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. 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. 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.

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 indicated under “recommended operating conditions” is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. 2011, February, Rev. 01 Free Datasheet http://www.datasheet4u.com/ IN1705 Table 3 – DC electrical characteristics (TA = - 40° to + 85°С) Symbol VIL VIH IOL IOH IOH1 VOH ILIL1 ILIL2 ILIL3 ILIH IСС VCCTP VTP Parameter Input voltage, low level Test conditions min Typical max Units VСС=from 2.4 to 5.5V Input voltage, high level VСС=from 2.4 to 5.5V Output current, low VСС=from 2.4 to 5.5V level (NMI, RST) VOL= 0.4V Output current, high VСС=from 4.5 to 5.5V level (WDS, NMI) VOH= 2.4V Output cur.
