CAT808
Low-Power Precision Voltage Detector
FEATURES
Ultra Low Current Consumption 2.4µA
Accurate Voltage Detection Threshold
Fine Voltage Detection Threshold Resolution
Open Drain Output (Active Low)
Industrial temperature range -40°C to +85°C
5-pin TSOT-23 and 3-pin SOT-89 RoHS
compliant packages
The CAT808 open-drain output is active low until the
V
DD
voltage exceeds the detection threshold. A low
hysteresis is built into the device to minimize output
“chatter”, while V
DD
passes through the detection
threshold, and the output transitions high.
After the CAT808 asserts the output high condition, it
continues to monitor V
DD
until it drops below the
detection threshold, when the output goes low until
V
DD
once again exceeds the detection threshold.
DESCRIPTION
The CAT808 is a high-precision voltage detector
designed for monitoring single cell and multi-cell batteries.
Voltage detection thresholds between 2.0V and 3.5V are
provided with 0.1V resolution and ±3.0% accuracy.
APPLICATIONS
Battery-Powered Systems
Power Supply Monitoring
Handheld and Portable Equipment
Processor Supervisor Reset
