Ordering Information
The FS8822 series are highly accurate, ultra-low
current consumption voltage detectors, developed
using CMOS process. A delay circuit is built-in for
microprocessor supervisory circuits in MCU and
digital systems. Two output forms N-channel
open-drain and CMOS output are available. The
device is ideal for battery- powered MCU systems or
portable devices which require low current
consumption.
The FS8822 consists of a comparator, a voltage
reference unit, a resistor divider, an output driver, a
hysteresis circuit, and a delay circuit. The detection
voltage is fixed internally with
±2.0%
accuracy by
advanced trimming technology.
The devices are available in SOT-23, SOT-89, and
TO-92 packages.
