NCP304A Voltage Detector Series The NCP304A is a second generation ultralow current voltage detector. This device is specifically designed for use as a reset controller in portable microprocessor based systems where extended battery life is paramount. This device features a highly accurate undervoltage detector with NCP304A MAXIMUM RATINGS (Note 1) Rating Symbol Value Unit Input Power Supply Voltage (Pin 4) V 12 V in Output Voltage (Pin 3) V V OUT 0.3 to V +0.3 Complementary, NCP304A in Output Current (Pin 3) (Note 2) I 70 mA OUT Thermal Resistance, JunctiontoAir 285 C/W R JA Maximum Junction Temperature T +125 C J Storage Temperature Range T 55 to +150 C stg Latchup Performance (Note 3) I mA LATCHUP 500 Positive 170 Negative Stresses exceeding Maximum Ratings may damage the device. Maximum Ratings are stress ratings only. Functional operation above the Recommended Operating Conditions is not implied. Extended exposure to stresses above the Recommended Operating Conditions may affect device reliability. 1.
