CAT808
Low-Power Precision
Voltage Detector
Description
The CAT808 is a high−precision voltage detector designed for
monitoring single cell and multi−cell batteries. Voltage detection
thresholds between 2.0 V and 3.5 V are provided with 0.1 V resolution
and 3.0% accuracy.
http://onsemi.com
The CAT808 open−drain output is active low until the V voltage
DD
exceeds the detection threshold. A low hysteresis is built into the
5
1
device to minimize output “chatter”, while V
passes through the
DD
detection threshold, and the output transitions high.
After the CAT808 asserts the output high condition, it continues to

monitor V until it drops below the detection threshold, when the
DD
output goes low until V once again exceeds the detection threshold.

Stresses exceeding Maximum Ratings may damage the device. Maximum Ratings are stress ratings only. Functional operation above the
Recommended Operating Conditions is not implied. Extended exposure to stresses above the Recommended Operating Conditions may affect
device reliability.
1. The Minimum DC input voltage is −0.5 V. During transitions, inputs may undershoot to −2.0 V for periods of less than 20 ns. Maximum DC
voltage on output pins is V +0.5 V, which may overshoot to V +2.0 V for periods of less than 20 ns.

Operation – Voltage Detector
The CAT808 has an active low output that asserts (pulls
low) when the supply voltage drops below the detection

threshold voltage (V
). The open−drain output requires
DET
an external pull−up resistor between the output pin and the
supply voltage (as shown in the typical application
diagram). On power−up, OUT is held active low until the

supply voltage (V ) rises above V . While V is above
