General Description
The AF70XXM series devices are a set of three
terminal low power voltage detectors implemented
in CMOS technology. Each voltage detector in the
series detects a particular fixed voltage ranging
from 0.9V to 5.0V. The voltage detectors consist of
a high-precision and low power consumption
standard voltage source as well as a comparator,
hysteresis circuit, and an output driver (CMOS
inverter or NMOS open drain). CMOS technology
ensures low power consumption.
Although designed primarily as fixed voltage
detectors, these devices can be used with external
components to detect user specified threshold
voltages.
