■ General Description
The XC61A is a highly precise detector series manufactured using CMOS
and laser trimming technologies.
■ Features
Highly accurate: Detect voltage ±2% (±1% for semi-custom products)
Low power consumption: Typ.1.0µA (VIN=2V)
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.
Selectable detect voltage: 0.8V ~ 2.0V in 0.1V increments.
Operating voltage: From 0.7V ~ 6.0V.
Temperature Characteristics: Typ.±100ppm/
:
Output configuration: N-channel open drain or CMOS
Ultra small package: SOT-23 (150mW) mini-mold and SOT-89 (500mW)
