ME70XXA Voltage Detector
General Description
The ME70XXA series is 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 2.4V to 5V. The
voltage detectors consist of a high-precision voltage
divider circuit, band gap voltage source, a comparator
and an output driver. 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 (NMOS
open drain type only).
