| TPS830(F) TOSHIBA Photo-IC Si Monolithic Photo-IC TPS830(F) Unit : mm Lead(Pb)-Free High-Speed Optical Remote Controllers Wireless Mouse, Wireless keyboard IR Data Communications * * * * * Photodiode, I-V converter, band-pass filter and AGC amplifier all incorporated in a single chip Carrier frequency: fo = 455kHz (typ.) Supply voltage: VCC = 5V Visible light cut-off frequency: > 700nm TLN105B(F) and TLN231(F) available as infrared LEDs for remote controllers TOSHIBA Weight: 0.3 g (typ.) 0-6A1 Absolute Maximum Ratings (Ta = 25C) Characteristic Supply voltage Output current Operating temperature range Storage temperature range Soldering temperature range (5 s) Symbol VCC IO Topr Tstg Tsol Rating 7 10 -20~60 -30~100 260 Unit V A C C C Note: Using continuously under heavy loads (e.g. the application of high temperature/current/voltage and the significant change in temperature, etc.) may cause this product to decrease in the reliability significantly even if the operating conditions (i.e. operating temperature/current/voltage, etc.) are within the absolute maximum ratings and the operating ranges. Please design the appropriate reliability upon reviewing the Toshiba Semiconductor Reliability Handbook ("Handling Precautions"/"Derating Concept and Methods") and individual reliability data (i.e. reliability test report and estimated failure rate, etc). 1 2007-10-01 TPS830(F) Optical And Electrical Characteristics (VCC = 5V, Ta = 25C, C = 1000pF: Note 1) Characteristic Supply voltage Supply current Electromagnetic sensitivity Transmission range High-level output voltage Low-level output voltage On pulse width Off pulse width Carrier frequency Peak sensitivity wavelength Radiation angle Symbol VCC ICC ES E=0 (Note 5) Test Condition Min 3 3 4 16 (Note 6) (Note 6) 55 25 Typ. 5 1.2 250 6 25 63 455 900 63 30 Max 7 3 0.5 40 Unit V mA Vp-p / m m V V s s kHz nm L (Note 3) The burst wave shown in Note VOH VOL TON TOFF fo P H V 4 is transmitted by a standard transmitter (Note 2). External light intensity < 500 lx Output current < 10A Horizontal angle, L / 2 Vertical angle, L / 2 Note 1: Measurements for the TPS830(F) are based on a standard circuit which includes a 1000-pF capacitor between VO and GND to prevent oscillation. Note 2: Standard transmitter In the figure above, the transmitter output VOUT is 80m Vpp. The TPS703(F) in this application has a short-circuit current of Isc = 1.24A when measured at E = 0.1mW/cm2. (E is the radiant incidence when a CIE standard light source A is used.) 20cm 10k 10F +10V VOUT GND TPS703(F) Transmitter (TLN115A(F) is used.) f0 = 455kHz Duty = 50% 10k Note 3: Transmission range L Standard transmitter (TLN105B(F)) L L is the maximum distance at which burst waves can be received from the transmitter unit, and at which data can be processed by the receiver unit. Note that when signals other than the recommended burst wave are transmitted, the transmission range may be reduced or a malfunction may occur. (*) The TLN105B(F) is used as the standard LED transmitter. If the TLN231(F) is used instead, the transmission range is 1.2 times that of the TLN105B(F). Example: 6m (with TLN105B(F)) 10.1m (with TLN231(F)) 2 2007-10-01 TPS830(F) Note 4: Burst wave 30s 55s VCC 2.5V GND TON TOFF Carrier frequency:fo = 455kHz Duty = 50% VOH VOL Note 5: Electromagnetic sensitivity TPS830(F) d 50 VP ES = VP/d (VP-P / m) Mount the device between two parallel boards separated by a distance of d. Apply voltages modulated using frequencies ranging from 10kHz to 50MHz across the boards and read off the voltage at which noise is generated in the output from the device. (*) Usage in strong electromagnetic fields may affect the device. Please evaluate product in this type of environment before releasing them for actual use.

GND Bit Pattern Designing Example (reference) * Example of code signal = 11010010 Sequence of LED signals = 1 must be avoided. If LED signals of 1 sequence, TPS830(F) may not receive LED signals properly. After an LED signal of 1, 0 must be sent (55 or longer interval necessary). Please take this into account when designing a bit pattern. The following shows the bit pattern t example that is converted at first code signals to LED signals as shown on the right diagram. Precautions 1. 2. 3. 4. 5. 6. To stabilize the power line, insert a bypass capacitor of up to 0.01F between VCC and GND, close to the device. At power-on the internal circuit takes about 100s to stabilize. During this period the output signal is unstable and may change. To avoid unnecessary oscillation, insert a bypass capacitor of 1000pF between VCC and GND. When using the device, please take the device's characteristics, the operating environment and the characteristics of pairing LED device into considerations. Soldering temperature: 260C, soldering time : 5s (Soldering must be performed under the 2mm from the body of the device.) When forming the leads, bend each lead under the 2mm from the body of the device. Soldering must be performed after the leads have been formed. 4 2007-10-01 TPS830(F) ICC - Ta 1.6 1.4 (typ.) 1.2 Relative L - Ta (typ.)
