PSD ON CHIP DISTANCE DETECTION SIGNAL PROCESSOR
DESCRIPTION M52959FP is a semiconductor integrated circuit built-in PSD(Position Sensitive Device) and distance detection signal processor for 3V supply voltage. This device transforms each signal current(I1 and I2) from PSD sensor to the voltage, and outputs it as the 4 Zone data after doing calculation of I1/(I1+I2). FEATURES * PSD on chip (Sensor size=0.5mm x 0.7mm) * Wide operating supply voltage range Vcc=2.0V to 5.5V * Built-in clamp circuit PIN CONFIGURATION (TOP VIEW)

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.
