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 dev.
