THE CDT7230 SERIES

1. Non-adjusting voltage detector by using CMOS Technology, 2.0-15.0VDC operating range.

2. The detecting voltage is fixed internally, and can be changed by new masking.

3. Composed of Standard Voltage Source, a Comparator, a Hysteresis Circuit, and an Output

Driver.

4. Output Structure is a N-ch Open-Drain Output.

5. Normally LED is off. It will turn on when voltage is low.
