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.

Features

• Quiescent Current of 0.5 A 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

• Pb−Free Packages are Available

T ypical Applications

• Microprocessor Reset Controller

• Low Battery Detection

• Power Fail Indicator

• Battery Backup Detection

Maximum ratings are those values beyond which device damage can occur. Maximum ratings applied to the device are individual stress limit values (not normal operating conditions) and are not valid simultaneously . If these limits are exceeded, device functional operation is not implied, damage may occur and reliability may be affected.

1. This device series contains ESD protection and exceeds the following tests: Human Body Model 2000 V per MIL−STD−883, Method 3015. Machine Model Method 200 V.

2. The maximum package power dissipation limit must not be exceeded.

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 (V

), and the reset output (Pin 1) will be in the high state

DET+

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 (V

). This sequence of events causes the Reset

DET−

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 V

. The voltage detector

DET+

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.

Device Thresholds

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.

NOTE: The ordering information lists standard undervoltage thresholds with active low outputs. Additional active low threshold devices,

ranging from 0.9 V to 4.9 V in 100 mV increments and NCP300/NCP301 active high output devices, ranging from 0.9 V to 4.9 V in 100 mV increments can be manufactured. Contact your ON Semiconductor representative for availability. The electrical characteristics of these additional devices are shown in Tables 1 through 4.
