VOLTAGE DETECTOR

GENERAL DESCRIPTION

The NJU7706/07 is a high precision voltage detector with a

built-in delay time generator of fixed time.

The NJU7706/07 is useful for preventing malfunction of

microprocessor or DSP through monitoring power supply voltage.

The delay function achieves set wait time when supply voltage

is unstable. Moreover, the delay function can make a sequence

that other devices in application work and stabilize before

microcomputer or DSP works.

The detection voltage is internally fixed with an accuracy of 1.0%,

and three fixed delay times 50ms, 100ms and 200ms are

available. Manual reset function can output reset signal

irrespective of detection voltage.

NJU7706 is Nch. Open Drain and NJU7707 is a C-MOS output

type.

Small packaging makes NJU7706 and NJU7707 suitable for

space conscious applications.
