Frequently Asked Questions
What is the maximum output current per channel on the TLC59281RGET?
The TLC59281RGET supports a constant output current range of 5mA to 40mA per channel, set by an external resistor (REXT). All 16 channels share the same reference resistor, ensuring matched current output across channels for uniform LED brightness.
How many LED channels can the TLC59281RGET control, and can multiple devices be cascaded?
The TLC59281RGET controls 16 independent constant-current LED channels. It supports daisy-chaining via its SPI-compatible serial interface, allowing multiple TLC59281 devices to be cascaded together to drive 32, 48, or more channels using a single microcontroller SPI bus.
What interface does the TLC59281RGET use and what voltage levels are supported?
The TLC59281RGET uses a 3-wire SPI-compatible serial interface (SDI, CLK, LE) for data input and latch control. It supports both 3.3V and 5V logic levels, making it compatible with a wide range of microcontrollers including those based on ARM Cortex-M, AVR, and PIC architectures.
What package is the TLC59281RGET available in, and what are the dimensions?
The TLC59281RGET is offered in a 24-pin VQFN (QFN) package with a compact 4mm x 4mm footprint. The small form factor makes it well suited for high-density PCB layouts in LED signage, display, and industrial control applications where board space is limited.
Where can I buy the TLC59281RGET and what is the typical price?
The TLC59281RGET is available through FindMyChip starting from $0.6642 per unit. Stock is available with worldwide shipping. You can submit a quote request to receive bulk pricing and lead time information for your specific quantity requirements.
