NCP300, NCP301 Voltage Detector Series The NCP300 and NCP301 series are second generation ultra−low current voltage detectors. These devices are specifically designed for use as reset controllers in portable microprocessor based systems where extended battery life is paramount. Each series features a highly accurate undervoltage detector with www.onsemi.com hysteresis which prevents erratic system reset operation as the comparator threshold is crossed. MARKING DIAGRAM The NCP300 series consists of complementary output devices that 5 are available with either an active high or active low reset output. The TSOP−5/ NCP301 series has an open drain N−Channel output with either an 5 SOT23−5 xxx AYW(cid:2) (cid:2) active high or active low reset output. 1 CASE 483 1 The NCP300 and NCP301 device series are available in the Thin TSOP−5 package with standard undervoltage thresholds. xxx = Specific Device Code Additional thresholds that range from 0.9 V to 4.9 V in 100 mV steps A = Assembly Location Y = Year can be manufactured.

NCP300, NCP301 V TRANSIENT REJECTION FACTORS TO BE CONSIDERED FOR VOLTAGE CC The NCP300 and NCP301 series provides accurate V OPTION SELECTION CC monitoring and reset timing during power−up, The following hysteresis graph depicts V DET−_min/max power−down, and brownout/sag conditions, and rejects and V for an active low Reset device: DET+_min/max negative glitches on the power supply line. Figure 22 shows the maximum transient duration vs. maximum negative Output excursion (overdrive) for glitch rejection. Any combination VDET−_typ of duration and overdrive which lies under the curve will not generate a reset signal. A below−V condition (on the CC right) is detected as a brownout or power−down. Typically, any transient that goes 100 mV below the reset threshold and lasts 5.0 (cid:2)s or less will not cause a reset pulse. VDET−_min VDET−_max VDET+_min VDET+_max Transient immunity can be improved by adding a capacitor in close proximity to the V pin of the NCP30x.

When the input voltage falls outside of the window established by the upper and lower device OV 1 Output thresholds, the LED will turn on indicating a fault. As the input voltage falls within the NCP301 window, increasing from 1.0 V and exceeding the active low device’s hysteresis HSN43T1 Reset Output threshold, or decreasing from the peak towards 1.0 V and falling below the active high device’s undervoltage threshold, the LED will turn off.
