DISTANCE DETECTION SIGNAL PROCESSING
FOR 3 V SUPPLY VOLTAGE
REJ03F0039-0100Z
Rev.1.0
Sep.16.2003
Description
M61006FP is a semiconductor integrated circuit including distance detection signal processing circuit for 3 V supply
voltage. This device transforms each optical inflow current I1 and I2 from PSD SENSOR into the voltage, and
integrates the output after doing calculation corresponds to I1 / (I1+I2), and outputs it as the voltage data.
Features
• Wide supply voltage range: Vcc = 2.2 to 5.5 V
• Including clamp level switching circuit
(It is possible to set a clamp level to 15 points with outside control.)
• Including infinity discrimination function
(clamp on detection function)
• Including POWER ON RESET function
• Including simple temperature detection function
(It is possible to correct temperature with transmitting this output to the microcomputer. )
Application
• Auto focus control for a camera, short distance sensor, etc.
Recommended Operating Condition
• Supply voltage range …… 2.2 V to 5.5 V
• Rated supply voltage …… 3.0 V

a. The dielectric polarty contermeasure of integlation capacitance:
The dielectric polarity contermeasure circuit of integration capacitance run between reset and rise edge of
first CONT pin.
b. CH rapid charge:
After reset cancel, CH capacitance is charged rapidy between the fall edge of first clock and second ones.
c. AFOUT pin reset:
After reset cannel, accumulated chage at capacitance added to AFOUT pin is removed
between the fall clock edges of 1 to 2 and 5 to 6.
d. Temperrature correct integlation:
After reset cannel, temperature correct integration is carried out betweeen the fall edge of 3rd clock and
4th clock. This voltage of temperature corrent integration mentioned above is maintained at AFOUT pin.
This voltage is currected temperature (including time charge correct of AFOUT pin added capacotance)
as compared with base voltage estabilished previously.
e. Stationaly light hold:
After 7th clock from reset cuncel (from 7th clock rise to 8th clock rise), stationary light hold is carried out over
and over.
f. Distance measurement integration:
After 7th clock from reset cancel (from 7th clock fall to 8th clock rise ), distance measurement integration is
carried out over and over.
