VOLTAGE DETECTORS WITH

BUILT-IN DELAY TIME

DESCRIPTION

The UTC 81CXXX and 81NXXX series are good

performance voltage detector and manufactured by CMOS

technologies with highly accurate, low power consumption. A

delay circuit is built-in to each detector, therefore, peripherals

are unnecessary and high density mounting is possible. Detect

voltage is extremely accurate with minimal temperature drift.

Both CMOS and N-channel open drain output configurations are

available.

FEATURES

*Highly Accurate : Detect voltage ± 2%

*Built-In Delay time :

1ms ~ 50ms,

50ms ~ 200ms,

200ms ~ 400ms,

*Detect Voltage Temperature Characteristics:

TYP± 100ppm/℃

*Wide Operating Voltage Range : 0.7V ~ 10.0V
