XC6126
Series
Ultra Small, Highly Accurate, Single Voltage Detector
ETR0214-005a
■GENERAL
DESCRIPTION
The XC6126 series is an ultra small, highly accurate CMOS single voltage detector with very low power consumption. The
device includes a highly accurate reference voltage source and uses laser trimming technologies, it maintains high accuracy
over the full operation temperature range.
The device is available in both CMOS and N-channel open drain output configurations.
Ultra small package USPN-4B02 is ideally suited for small design of portable devices and high densely mounting
applications. The conventional package SSOT-24 is also available for upper compatible replacements.
