PHOTO IC Photo IC for encoder S4506 Photo IC for photointerrupters with encoder functions S4506 incorporates a 4-element photodiode array that provides 2-phase digital output in response to the input light status. Photointerrupters with encoder functions can be easily configured by using S4506. Features Applications l 2-phase (phases A and B) digital output l Integrated with 4-element photodiode (pitch: 0.39 mm) l Direct TTL connection l Miniature plastic package l Encoders for office machine, robots, and NC machines ■ Absolute maximum ratings (Ta=25 °C) Parameter Symbol Value Supply voltage Vcc -0.5 to +7 Output current IO 20 Power dissipation *1 Po 250 Operating temperature Topr -30 to +80 Storage temperature Tstg -40 to +85 Soldering 230 °C, 5 s, at least 1.8 mm away from package surface *1: Derate power dissipation at a rate of 3.3 mW/°C above Ta=25 °C Unit V mA mW °C °C - ■ Electrical and optical characteristics (Ta =25 °C, Vcc=5 V, unless otherwise noted) Parameter Supply voltage Low level output voltage High level output voltage Current consumption Peak sensitivity wavelength Slit movement speed Duty ratio *4 Symbol Vcc VOL VOH ICCL ICCH λp Vp DA DB Condition IOL=8 mA IOH=0 mA VOA=VOB= “L” VOA=VOB= “H” Ev=200 lx *2 *3 Ev=200 lx *2 f=2.5 kHz Min. 4.5 4.5 - Typ. 0.1 6 3 870 - Max. 5.5 0.4 12 12 10,000 Unit V V V mA mA nm slit/s 35 50 65 % Transfer Phase f=2.5 kHz, Ev=200~700 lx *2 60 90 120 deg θAB characteristics difference Threshold lx EVD “A” light source, f=2.5 kHz 30 120 illuminance *5 *2: Ev is illuminance emitted from a CIE standard “A” light source (tungsten lamp). *3: A collimated light source and a recommended slit moving at a constant speed are used. [Delay time between the instant that the slit passes through the output transition position and the actual output transition should be less than 1/8 of the slit cycle.] *4: See next page. *5: Minimum illuminance from an “A” light source when the duty ratio of phases A and B is between 35 and 65 %. 1 Photo IC for encoder ■ Block diagram ■ Dimensional outline (unit: mm) CONSTANT VOLTAGE CIRCUIT I3 P1 S4506 5.0 CENTER OF ACTIVE AREA 2.5 ± 0.2 VOA + I1 5.2 ± 0.3 (INCLUDING BURR) Vcc 2.0 1.0 PD 3 1.0 (DEPTH 0.15 MAX.) 0.55 + (0.8) P4 0.45 I2 GND PD 4 PHOTODIODE 5˚ VOB 2.0 (DEPTH 0.15 MAX.) 10˚ P3 (1.0) I4 16.5 ± 1.0 PD 2 5.0 2.5 ± 0.2 5.2 ± 0.3 (INCLUDING BURR) - PD 1 P2 PRE-AMPLIFIER HYSTERESIS OUTPUT CIRCUIT COMPARATOR (1.27) (1.27) (1.27) OUTPUT P1 < P3 P1 < P3 P1 > P3 P1 > P3 P2 > P4 P2 < P4 P2 > P4 P2 < P4 VOA L L H H 0.25 +0.15 -0.1 (SPECIFIED AT THE LEAD ROOT) VOB L H L H 0.7 ± 0.15 INPUT 10˚ PHOTOSENSITIVE SURFACE VOA Vcc GND VOB KPICC0012EC Tolerance unless otherwise noted: ±0.1, ±2˚ Shaded area indicates burr.
