VOLTAGE DETECTOR
■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.
