SGM892B/SGM893B

Standard CMOS Voltage Detector ICs

GENERAL DESCRIPTION

FEATURES

The SGM892B and SGM893B are low power

consumption voltage detectors with high accuracy

detection. These miniature devices offer tremendous

flexibility with an adjustable threshold that is available

from 1V to 5V with 0.1V increments. These devices are

ideal for use in power-supply sequencing, reset

sequencing, and power-switching applications.

● High Accuracy Detection: ±1% (TYP)

● Low Power Consumption: 0.4μA (TYP) at V_IN= 1V

● Detection Voltage Range: 1V to 5V (0.1V Increments)

● Operating Voltage Range: 1V to 6V

● Detection Voltage Temperature Coefficient:

±40ppm/℃ (TYP)

● Manual-Reset Input (SGM893B Only)

● N-Channel Open-Drain Output

The VOUT pin is an N-channel open-drain output with

active-low reset. An active-low manual-reset input (nMR)

is included in SGM893B.

● -40℃ to +125℃ Operating Temperature Range

● Small Packaging:

SGM892B Available in Green SOT-23-5, SOT-23-3

and UTDFN-1×1-4L Packages

The SGM892B is available in Green UTDFN-1×1-4L,

SOT-23-3 and SOT-23-5 packages. The SGM893B is

available in Green SOT-23-5 and UTDFN-1×1-4L

packages. They are specified over the -40℃ to +125℃

operating temperature range.
