Controls
1. First,STB terminal set Low,then Power On Reset circuit operate.This Power On Reset circuit resets Built-in logic
circuits.
2. After Power On Reset circuit stoped,Surround light Hold Capacitor quik charge between the first CONT pulse
edge from High to Low and second CONT pulse edge from High to Low.
3. After quik charge,set Stabilization Period for about 1ms.
4. After quik charge,Surround light hold between the first CONT pulse edge from Low to High and second CONT
pulse edge from Low to High.
5, After quik charge,Zone judges at the first CONT pulse edge from High to Low and output the Zone Data to
OUT1,OUT2 terminals by 2bit at next CONT pulse edge from Low to High.
6. It can repeat distance detection by continuing control of 4 and 5.
7. It needs the signal synchronized with timing of Surround light hold as radiation control signal of IRED.
