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 hysteresis which prevents erratic system reset operation as the comparator threshold is crossed. The NCP300 series consists of complementary output devices that are available with either an active high or active low reset output. The NCP301 series has an open drain N−Channel output with either an active high or active low reset output. The NCP300 and NCP301 device series are available in the Thin TSOP−5 package with standard undervoltage thresholds. Additional thresholds that range from 0.9 V to 4.9 V in 100 mV steps can be manufactured. http://onsemi.com MARKING DIAGRAM 5 5 1 xxx A Y W G Features • • • • • • • Quiescent Current of 0.5 mA Typical High Accuracy Undervoltage Threshold of 2.0% Wide Operating Voltage Range of 0.8 V to 10 V Complementary or Open Drain Reset Output Active Low or Active High Reset Output Specified Over the −40°C to +125°C Temperature Range (Except for Voltage Options from 0.9 to 1.1 V) Pb−Free Packages are Available 1 = Specific Device Code = Assembly Location = Year = Work Week = Pb−Free Package (Note:Microdot may be in either location) PIN CONNECTIONS Reset Output 1 Input 2 Ground 3 5 N.C. 4 N.C.

NCP300H/1L Series 4.5 V Reset Output Sink Current versus Output Voltage http://onsemi.com 14 NCP300, NCP301 OPERATING DESCRIPTION The NCP300 and NCP301 series devices are second generation ultra−low current voltage detectors. Figures 20 and 21 show a timing diagram and a typical application. Initially consider that input voltage Vin is at a nominal level and it is greater than the voltage detector upper threshold (VDET+), and the reset output (Pin 1) will be in the high state for active low devices, or in the low state for active high devices. If there is a power interruption and Vin becomes significantly deficient, it will fall below the lower detector threshold (VDET−). This sequence of events causes the Reset output to be in the low state for active low devices, or in the Input Voltage, Pin 2 Reset Output (Active Low), Pin 1 high state for active high devices. After completion of the power interruption, Vin will again return to its nominal level and become greater than the VDET+. The voltage detector has built−in hysteresis to prevent erratic reset operation as the comparator threshold is crossed. Although these device series are specifically designed for use as reset controllers in portable microprocessor based systems, they offer a cost−effective solution in numerous applications where precise voltage monitoring is required. Figure 25 through Figure 32 shows various application examples. Vin VDET+ VDET− Vin VDET+ VDET− 0V Reset Output (Active High), Pin 1 Vin VDET+ VDET− 0V Figure 21. Timing Waveforms http://onsemi.com 15 NCP300, NCP301 VCC TRANSIENT REJECTION The NCP300 and NCP301 series provides accurate VCC monitoring and reset timing during power−up, power−down, and brownout/sag conditions, and rejects negative glitches on the power supply line. Figure 22 shows the maximum transient duration vs. maximum negative excursion (overdrive) for glitch rejection. Any combination of duration and overdrive which lies under the curve will not generate a reset signal. A below−VCC condition (on the right) is detected as a brownout or power−down. Typically, any transient that goes 100 mV below the reset threshold and lasts 5.0 ms or less will not cause a reset pulse. Transient immunity can be improved by adding a capacitor in close proximity to the VCC pin of the NCP30x. PROPAGATION DELAY VARIATION On the other hand (see above paragraph), a minimum overdrive value from Vthreshold to VCC must be respected. That means Vin (minimum value of VCC) must be higher enough than VDET+ (VDET− + hysteresis) at the risk of significantly increasing propagation delay. (Figure 24) This propagation delay is temperature sensitive. To avoid acceptable time response, a minimum 100 mV difference between Vin and VDET+ must be selected.

When the input voltage falls outside of the window established by the upper and lower device thresholds, the LED will turn on indicating a fault. As the input voltage falls within the window, increasing from 1.0 V and exceeding the active low device’s hysteresis 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. The device thresholds shown can be used for a single cell lithium−ion battery charge detector. Figure 27.
