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.

http://onsemi.com

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.

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.

Figures 37 and 38 show a timing diagram and a typical

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
