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.

NCP300 and NCP301 series are measured with a 10 pF capacitive load. NCP301 has an additional 470 k pull-up resistor connected from the reset output to +5.0 V. The reset output voltage waveforms are shown for the active low `L' devices. The upper detector threshold, VDET+ is the sum of the lower detector threshold, VDET- plus the input hysteresis, VHYS.

OPERATING DESCRIPTION The NCP300 and NCP301 series devices are second generation ultra-low current voltage detectors. Figures 21 and 22 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 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 22 through Figure 29 shows various application examples.

Vsupply Fault 10 V Active High Device Thresholds Active Low Device Thresholds 1.0 V UV Fault OK OV Fault OV Fault OK UV Fault Input 2 The above circuit combines an active high and an active low reset output device to form a window detector for monitoring battery or power supply voltages. 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. Input 1 Reset Output Output 2 Input 1 Reset Output

Comparator hysteresis can be increased with the addition of resistor RH. The hysteresis equations have been simplified and do not account for the change of input current Iin as Vin crosses the comparator threshold. The internal resistance, Rin is simply calculated using Iin = 0.26 mA at 2.6 V.

A simple voltage monitor can be constructed by connecting several voltage detectors as shown above. Each LED will sequentially turn on when the respective voltage detector threshold (VDET- +VHYS) is exceeded. Note that detector thresholds (VDET-) that range from 0.9 V to 4.9 V in 100 mV steps can be manufactured.
