POWER SUPPLY CHECK MICROCIRCUIT WITH HOST PRIMARY SUPPLY

MONITORING CIRCUIT

IN1705D microcircuit is purposed to check power supply and to start up microcontroller

and microprocessor systems. It is applied to ensure regular standard operation of the circuit

when the device is switched on\off and also when there is alarm emergency dropping of

supply voltage.

Physically the microcircuit is made in 8-pin SO-package MS012AA.

LSIIC Characteritics:

• Standard supply voltage

5,0 В

• Operation temperature range Т = from -40°to +85°С

• RESET signal generation when ^Apower supply is provided for regular start-up of

microprocessor

RESET signal generation when power supply is dropped below operation one to exclude

incorrect operation of microprocessor.

• RESET signal generation when reset key is pressed

• Option of threshold voltage programming when RESET signal is generated

Microcircuit includes:

Pins’ designation in package

•

reference voltage source

• two analog comparators

guard timer

• digitizer, (digital sampler)

digital delay

•

Functions performed

• RESET signal generation by fixed supply voltage level

• RESET signal generation from external RESET key

• Generation of guard timer state signal

Alarm interrupt of host power supply
