Photo IC for laser beam synchronous detection S9684 series S11282-01DS High-sensitivity and high-speed photo IC for high precision printing The S9684 series and S11282-01DS photo IC use a dual-element Si PIN photodiode and compare the two signals to obtain a highly stable output even when laser power or ambient temperature fluctuates. The current amplifier is available with two gain levels (6 times and 20 times) according to laser power to be used. The S11282-01DS operates at a low voltage (3.3 V) compatible with low-voltage peripheral components. HAMAMATSU also provides single-element Si PIN photodiode types (S9703/S10317 series). Features Applications Photo IC for precision printing Print start timing detection for laser printers, digital copiers, fax machines, etc. High sensitivity Current amplifier gain: 20 times (S9684, S11282-01DS) 6 times (S9684-01) Digital output Small package Suitable for lead-free solder reflow Photosensitive area (PD1: 2.5 × 0.3 mm, PD2: 2.5 × 0.5 mm) Low voltage (3.3 V) operation (S11282-01DS) Absolute maximum ratings Parameter Supply voltage Power dissipation*1 Output voltage*2 Output current Ro1, Ro2 terminal current Operating temperature Storage temperature Reflow soldering conditions*3 Symbol Vcc P Vo Io IRO Topr Tstg Tsol Condition Ta=25 °C Ta=25 °C Ta=25 °C Ta=25 °C Ta=25 °C Value -0.5 to +7 300 -0.5 to +7 5 3 -25 to +80 -40 to +85 Peak temperature 240 °C, 1 time Unit V mW V mA mA °C °C - *1: Power dissipation decreases at a rate of 4 mW/°C above Ta=25 °C *2: Vcc=+0.5 V or less *3: JEDEC level 5a Note: Exceeding the absolute maximum ratings even momentarily may cause a drop in product quality.

The photodiode chip is internally connected to the IC chip as shown in the block diagram. The products should be used with terminals Ro1 and Ro2 connected to an external gain resistance. Two photocurrents are generated when a laser beam enters the dual-element photodiode. Each photocurrent is fed to the input terminal of the IC and, after being amplified by the current amplifier, flows to the external gain resistance. At this time, voltages VRO1 and VRO2 at terminals Ro1 and Ro2 are given by the following expression. VRO1 (VRO2)=A × S × PI × Ro1 (Ro2) [V] A: Current amplifier gain (S9684, S11282-01DS: 20 times, S9684-01: 6 times) S: Photodiode sensitivity [A/W] (approx. 0.45 A/W at 780 nm) PI: Input power [W] Ro1, Ro2: External gain resistance [Ω]; usable range 2 kΩ to 10 kΩ VRO1 and VRO2 are input to the internal comparator so the output Vo is "high" when VRO1 > VRO2 or "low" when VRO1 < VRO2. Note that VRO1 and VRO2 should not exceed 8 times of the voltage calculated from the threshold light level.
