81N33 - VOLTAGE DETECTORS

Download the 81N33 datasheet PDF. This datasheet also covers the 81NXXX variant, as both devices belong to the same voltage detectors family and are provided as variant models within a single manufacturer datasheet.

General Description

The UTC 81CXX and 81NXX 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.

Key Features

  • S.
  • Highly Accurate: Detect voltage ± 2%.
  • Built-In Delay time : 1ms ~ 50ms 50ms ~ 200ms 200ms ~ 400ms.
  • Detect Voltage Temperature Characteristics: TYP± 100ppm/°C.
  • Wide Operating Voltage Range : 0.7V ~ 10.0V.
  • Low Current Consumption : TYP 1.0μA (VIN=2.0V).

UNISONIC TECHNOLOGIES CO., LTD 81CXX/81NXX VOLTAGE DETECTORS WITH BUILT-IN DELAY TIME CMOS IC  DESCRIPTION The UTC 81CXX and 81NXX 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/°C * Wide Operating Voltage Range : 0.7V ~ 10.0V * Low Current Consumption : TYP 1.
