General Description
The XC61A is a highly precise detector series manufactured using CMOS
and laser trimming technologies.
The series is very accurate and offers standard voltage sourced low power
consumption.The series consists of hysteresis, output driver, and linear
characterised delay circuits, together with a comparator. Detect voltage is
extremely accurate with minimal temperature drift. Both CMOS and N-
channel open drain output configurations are available.
Integrating the above functions in a single, mini-molded package, the
XC61A series offers significant space saving and high-density mounting,
suitable for use with portable products.
