VOLTAGE DETECTOR IC
■THE CDT5430 SERIES
1. Non-adjusting voltage detector by using CMOS Technology.
2. 1.5 – 6.0VDC operating range.
3. The detecting voltage is fixed internally, and can be changed by new masking.
4. Composed of Standard Voltage Source, a Comparator, a Hysteresis Circuit,
And an Output Driver.
5. Output Structure is an N-ch Open-Drain Output.
6. Normally LED is OFF. It will turn on when voltage is low.
7. With ±0.1V Voltage Compensation Design by Pad Bonding Option
