NCP302, NCP303 Voltage Detector Series with Programmable Delay
The NCP302 and NCP303 series are second generation ultra-low current voltage detectors that contain a programmable time delay generator. 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 and an externally programmable time delay generator. This combination of features prevents erratic system reset operation. The NCP302 series consists of complementary output devices that are available with either an active high or active low reset. The NCP303 series has an open drain N-Channel output with an active low reset output.

NCP302 and NCP303 series are measured with a 10 pF capacitive load. NCP303 has an additional 470 k pullup resistor connected from the reset output to +5.0 V. The reset output voltage waveforms are shown for the active low `L' devices. Output time delay tD1 and tD2 are dependent upon the delay capacitance. Refer to Figures 30, 31, and 32. The upper detector threshold, VDET+ is the sum of the lower detector threshold, VDET- plus the input hysteresis, VHYS.

NCP302, NCP303
OPERATING DESCRIPTION The NCP302 and NCP303 series devices consist of a precision voltage detector that drives a time delay generator. Figures 37 and 38 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+). The voltage at Pin 5 and capacitor CD will be at the same level as Vin, 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-) and the external time delay capacitor CD will be immediately discharged by an internal N-Channel MOSFET that connects to Pin 5. 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 will turn off the N-Channel MOSFET and allow pullup resistor RD to charge external capacitor CD, thus creating a programmable delay for releasing the reset signal. When the voltage at Pin 5 exceeds the inverter/buffer threshold, typically 0.675 Vin, the reset output will revert back to its original state. The reset output time delay versus capacitance is shown in Figures 12 through 14. The voltage detector and inverter/buffer have built-in hysteresis to prevent erratic reset operation. 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 and time delay are required. Figures 38 through 45 show various application examples.

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.

Figure 45. Undervoltage Detection with Independent Reset Signal Control
This circuit monitors VDD for undervoltage. If the VDD input falls below the detector threshold (VDET-), then the capacitor on the CD pin will be immediately discharged resulting in the reset output changing to its active state indicating that an undervoltage event has been detected. The addition of a logic gate (Logic 1) provides for reset output control which is independent of VDD. If the output of the
logic gate is tristated the undervoltage detector will behave normally. If the tristate is de-asserted, the logic gate will pull the CD pin low resulting in the Reset Output pin changing to an active state. This independent control is useful in power supply sequencing applications when the Reset Output is tied to the enable input of an LDO or DC-DC converter.

Figure 46. Multi-Rail Supply Undervoltage Monitor with Power Good
This circuit monitors multiple power supply rails for undervoltage conditions. If any of the three power supplies are in an undervoltage condition, the NCP302 reset output will be immediately set to an active low level. All three power supplies must be above their minimum voltage levels for the NCP302 reset output to generate a "Power Good" level (Reset Output = Power Supply 1 or VP). Optionally, R1 may be added to provide a smaller effective CD pin pullup resistance, (RD'), where RD' = R1 || RD, with RD (internal CD pin pullup resistance)
approximately equal to 1.0 MW, and R1 > 5 kW. If R1 << RD, then R1 also can decrease the reset output delay time (tD2) variance over the operating temperature range. The Power Good signal time delay (tD2) can be estimated by: tD2 RD * CD, with RD in Ohms, and CD in Farads. If R1 is installed, then RD' is substituted for RD. RP is added only if using the NCP303 to replace the NCP302. This allows the Reset Output to be pulled up to VP, which can be the Power Supply 1 or an independent power supply rail.
