CAT808
Low-Power Precision Voltage Detector
DESCRIPTION
FEATURES
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.
Ultra Low Current Consumption 2.4µA
Accurate Voltage Detection Threshold
Fine Voltage Detection Threshold Resolution
Open Drain Output (Active Low)
The CAT808 open-drain output is active low until the
VDD voltage exceeds the detection threshold. A low
hysteresis is built into the device to minimize output
“chatter”, while VDD passes through the detection
threshold, and the output transitions high.
Industrial temperature range -40°C to +85°C
5-pin TSOT-23 and 3-pin SOT-89 RoHS
compliant packages
APPLICATIONS
After the CAT808 asserts the output high condition, it
continues to monitor VDD until it drops below the
detection threshold, when the output goes low until
VDD once again exceeds the detection threshold.

Notes:
(1) Stresses above those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings
only and functional operation of the devices at these or any other conditions outside of those listed in the operational sections of this
specification is not implied. Exposure to any absolute maximum rating for extended periods may affect device performance and
reliability.
(2) The Minimum DC input voltage is -0.5V. During transitions, inputs may undershoot to -2.0V for periods of less than 20ns. Maximum DC
voltage on output pins is VCC +0.5V, which may overshoot to VCC +2.0V for periods of less than 20ns.
(3) Latch-up protection is provided for stresses up to 100mA on all pins from -1V to VCC +1V.
(4) The temperature change ratio in the detection voltage [ppm/°C] is calculated by using the following equation:
Δ − VDET
ΔTA • -VDET
×1,000,000[ppm /º C]

CAT808
OPERATION – VOLTAGE DETECTOR
BLOCK DIAGRAM
The CAT808 has an active low output that asserts
(pulls low) when the supply voltage drops below the
detection threshold voltage (VDET). The open-drain
output requires an external pull-up resistor between
the output pin and the supply voltage (as shown in the
OUT
VDD

typical application diagram). On power-up, OUT is

REFERENCE
held active low until the supply voltage (VDD) rises
above VDET. While VDD is above VDET, OUT stays high
¯¯¯¯
¯¯¯¯
until VDD drops below VDET, then OUT once again
goes low.
