M61006FP Datasheet | Hitachi Semiconductor

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 microputer. ) Application - Auto focus control for a camera, short distance sensor, etc. Remended Operating Condition - Supply voltage range …… 2.2 V to 5.5 V - Rated supply voltage …… 3.0 V Block Diagram Vcc1 5 CHN Capacitance for stationary lihgt hold Vcc2 12 NC 16 TESTN 0.032 µF AFOUT 1 DIELECTRIC DIVIDEPOLE MEASURES CIRCUIT TEMPERATURE DETECTION CIRCUIT 1 µF I1 OUTPUT CIRCUIT 14 PSDN STATIONARY LIGHT REMOVE I/V TRANSFORM AMP RECKON I1 I1 + I2 HOLD HOLD I2 INFINITY JUDGE CIRCUIT 9 NC PSDF 11 CHF 1 µF Capacitance for stationary lihgt hold STATIONARY LIGHT REMOVE I/V TRANSFORM...
