Product 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.
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.
