    rmeza
    Based on feedback from its recent ti.com release, limited sample quantities of the TALP1000B dual-axis pointing mirror can now be purchased through the TI eStore. This eStore option allows purchase of 3 or 6 mirrors for evaluation. For quotes and availability of larger quantities of TALP1000B mirrors...

    Stephanie Waite
    Hi, I was wondering what was the largest size available is for the MEMS pointing mirrors. I am looking for something with a 6 or 7 mm diameter. I some of the literature, the largest MEMS mirrors available is 5 mm diameter. Are specs available for a part that large? For the TALP1000B, is there any...

    The Application Report DLPA009 shows code snippets from different sources, e.g. it mentions a file called "control.c". Does anyone know if these source files are available (for prototyping in a research project)?

    Hi, We ordered a sample TALP1000B device a few weeks back which arrived broken (mirror missing) & was replaced by the supplier Mouser UK. Last week I ordered a further two (again through Mouser UK) which arrived today both broken (one has mirror missing, the other detached). Given that two...

    sb57429
    Hello, I just wanted to check if the coil current at maximum rotation applies for one coil or the whole axis as the circuit schematic looks like there are two coils in parallel per axis which would give me 130mA max. per axis. How much current can the mirror take per coil/axis max. (e.g. in case...

  • Forum Post: TALP1000B Replacement Recommendations?

    Bradford Chew
    Since TI has announced that the TALP1000B is no longer recommended for new designs, does TI recommend a replacement for the TALP1000B? The TALP1000B works fine for my application. If TI is getting out of the analog MEMS business, has an alternate supplier been identified? Thanks! Brad

    Hi Mike, We do have long term life test data on a different product that uses the same SmCo magnets. A total of 64 parts were actuated for >20,000Hrs at 60C with no significant increase in drive current (no change in magnitization). Regards, Arthur

    Hi Mikhail, These devices are resoanant scanning mirrors. The error in the drive current measurement is +/- 5%. We saw no change to this level. Regards, Arthur

    Hi Jasna, Could you provide a basic application description (use the mirror in a pointing or scanning mode) and a basic discription of your PWM drive circuit. These will help us better answer your frequency question. Regards, Arthur

    Hi Mike, The TALP1000B does have mechanical rotation stops. These stops limit the maximum rotation angles to a value between 5 and 6 degrees. Regards, Arthur

    Hi Ash, The TALP1000B mirror is coated with a Au reflecting surface that will reflect over 95% on the incident laser power (typically ~98% in the near IR). The TALP1000B has resonant frequencies (mirror and gimbals) near 120Hz. Scanning the mirror at 800Hz with drive powers below 700mW will result...

    Hi Mike, The rotation stops are an integral part of the design. The TALP1000B has 8 magnets which (in conjuction with the 4 drive coils) provide the torgue required for rotation. Four magnets are easily visible on the reflective mirror side and 4 additional magnets are attached to the underside of...

    Hi Mike, Sorry I just now noticed you post. Average deflection efficiencies are calculated on the currents measured at constant angle, in this case, +/-5 degrees mechanical. "Average" means that only the +/-5 degree currents are used, small non-linearities produce slightly different deflection...

    Hi Mike, TI recommends that the TALP1000B be operated within the data sheet operational angle specification which is +/-5 degrees mechanical for both axis. All qualification and reliability testing was restricted to this angle range. The mirror hinges can be damaged if a current corresponding to large...

    Hi Mike, The TALP1000B uses a push/pull type actuator. The coil winding and magnet polarities are arranged so that coil current pushes up on one magnet and pulls down on the other. There is no force on the rotation axis so there should be no sag. The previous statement is strictly true only for small...

    Hi Ash, Applying 0.7V across pins 1 and 2 or across pins 11 and 12 should result in current flow in the circuit. Please verify that current is flowing (10mA for 0.7 V DC and 7.5mArms for 0.7 V AC). The current flow should result in mirror motion. If this is not the case then the divice may have been...
