What are the key features of TLC5916IPW-P?
- 8-channel constant-current outputs up to 120 mA each for uniform LED brightness across all channels
- SPI-compatible serial interface enables daisy-chaining multiple drivers with only 3 control lines
- Hardware output-enable pin provides PWM dimming down to 0% duty cycle without microcontroller overhead
What is TLC5916IPW-P used for?
The TLC5916IPW-P is designed for driving LED arrays in signage, industrial panel indicators, and consumer display backlights where consistent brightness across 8 channels is required. Its SPI daisy-chain capability allows a single microcontroller to control large LED matrices by cascading multiple devices. The constant-current architecture eliminates per-LED resistors, reducing BOM cost and PCB area in high-density LED applications.

Frequently Asked Questions
How many LEDs can a single TLC5916IPW-P drive, and what is the maximum output current per channel?
The TLC5916IPW-P provides 8 independent constant-current output channels, each capable of sinking up to 120 mA. This means one device can simultaneously drive 8 LEDs at full brightness. The constant-current design keeps LED forward current stable regardless of supply voltage variations, ensuring uniform luminance across all 8 outputs in indicator and display applications.
How does daisy-chaining TLC5916IPW-P devices scale an LED matrix beyond 8 channels?
Multiple TLC5916IPW-P devices share a common SPI bus by connecting the serial data output of one chip to the serial data input of the next. A 3-wire SPI interface — clock, data, and latch — controls up to dozens of cascaded drivers, expanding LED count in multiples of 8 channels per device. This architecture reduces GPIO pin usage on the host microcontroller to just 3 pins regardless of total LED count.
For an industrial panel with 64 LEDs, is TLC5916IPW-P a lower-cost alternative to discrete transistor arrays?
Yes. Using 8 cascaded TLC5916IPW-P devices to drive 64 LEDs eliminates 64 current-limiting resistors and discrete transistors, reducing BOM cost and PCB area significantly. The integrated constant-current sources maintain LED current accuracy within ±3% across channels, which discrete resistor networks cannot match without tight tolerance 1% resistors. The TSSOP-16 package occupies roughly 32 mm² per device, far less than equivalent discrete solutions.
