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.
■ FEATURES
● Precise Detection of Supply Voltage Down (VSA=4.2V±2.5%)
● Possible Detection of Optional Voltage Down (VSB=1.22V±1.5%)
● Possible Detection of Optional Over-loading
● Low Operating Current
(ICC≦560µA@VSB=5V)
● Reference Voltage can be taken out.
● Low Reset Validated Voltage
(V+=0.8V Typ.)
● Voltage Detection with Hystersis Feature
● Package Outline
DIP8, DMP8, SIP8
● Bipolar Technology
