CAT808

Low-Power Precision Voltage Detector

FEATURES

DESCRIPTION

Ultra Low Current Consumption 2.4µA

Accurate Voltage Detection Threshold

Fine Voltage Detection Threshold Resolution

Active Low Open Drain Output

The CAT808 is a high-precision voltage detector

designed for monitoring single cell and multi-cell batteries.

Voltage detection thresholds between 2.0V and 3.2V are

provided with 0.1V resolution and ±3.0% accuracy.

The CAT808 open-drain output is active low until the

V_DDvoltage exceeds the detection threshold. A low

hysteresis is built into the device to minimize output

“chatter”, while V_DDpasses through the detection

threshold, and the output transitions high.

Available in 5-pin TSOT- 23 and 3-pin SOT- 89

RoHS compliant packages

Industrial temperature range -40°C to +85°C

APPLICATIONS

Battery-Powered Systems

Power Supply Monitoring

After the CAT808 asserts the output high condition, it

continues to monitor V_DDuntil it drops below the

detection threshold, when the output goes low until

V_DDonce again exceeds the detection threshold.
