Other Parts Discussed in Thread: LP55281, TLC5951, TLC59116, TLC5941, TLC5940
Hi Experts,
May I ask for help? I am looking for an available alternative of TLC5947 for our customer.
The specific features they are interested in are the following:
- SPI interface (or control interface with max 4 wires)
- Constant current sink
- Channels can be combined to increase the power output capability of the chip
- Enough channels able to provide enough power to drive at least 4 LEDs at 150mA (combining channels)
- Cascadable (as many slave devices as possible)
- Individually controllable and dimmable via PWM
- Internal PWM clock
- Thermal shutdown and thermal pad for heat dissipation are desireable
- Maximum voltage applied to output as high as possible is a bonus
This should be it in terms of specification - for your reference, we are looking to control the chip using the Teknic ClearCore industrial motion controller: www.teknic.com/.../clearcore_user_manual.pdf
I have found LP55281, but was not sure if this will fit. If this wont fit, please help us by suggesting a better product that can meet the above requirements. Thank you so much.
Kind regards,
Gerald
