UC3843 Current Mode PWM Controller

The NCP/NCV302 and NCP/NCV303 series are second generation ultra-low current voltage detectors that include a programmable time delay generator. These devices are designed as reset controllers for portable microprocessor-based systems where long battery life is critical. Each family features a high-accuracy brown-out detector with hysteresis, and an externally programmable time-delay generator. This combination of features prevents erroneous system reset operations. The NCP/NCV302 family consists of complementary output devices and provides active high or active low reset. The NCP/NCV303 series has an open-drain N-channel output with an active-low reset output.
