Nisshinbo NJU2103A & NJU2103B System Reset ICs
Nisshinbo NJU2103A and NJU2103B System Reset ICs are power supply voltage monitoring ICs that instantaneously detect an abnormality and generate a reset signal. These abnormalities include power supply voltage cutoffs or drops. The NJU2103A and NJU2103B ICs can monitor two 5V power supply systems and arbitrarily set the voltage. These ICs are fully compatible with the NJM2103 supervisory ICs. Typical applications include industrial equipment, housing/facility equipment, OA equipment, and amusement equipment.
