NJU7707
NJU7707 is VOLTAGE DETECTOR manufactured by New Japan Radio.
- Part of the NJU7706 comparator family.
- Part of the NJU7706 comparator family.
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 microputer 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.
