NJM2103

SYSTEM RESET IC

■

GENERAL DESCRIPTION

NJM2103

is supply voltage supervisory IC to detect the abnormal

conditions, such as shut down of all supply voltages at once, or sudden

voltage down and then generate the reset signal. It supervises both 5V

supply voltage and the voltage optionally set up.
