Frequently Asked Questions
What is the maximum output current per channel for the TLC5917IPW?
The TLC5917IPW supports up to 120mA maximum output current per channel. The output current is set globally for all 8 channels using a single external resistor connected to the REXT pin, allowing easy adjustment to match your LED forward current requirements.
How do you control the TLC5917IPW LED driver?
The TLC5917IPW uses an SPI-compatible serial interface with SDI (serial data input), CLK (clock), and LE (latch enable) signals. Data is shifted in serially on the rising edge of CLK, and all 8 channel outputs update simultaneously when LE is pulsed high. Multiple devices can be daisy-chained by connecting SDO of one device to SDI of the next.
What package does the TLC5917IPW come in?
The TLC5917IPW comes in a 20-pin TSSOP (TSSOP-20) surface-mount package. The 'PW' suffix in the part number denotes the TSSOP package. This compact package is well-suited for space-constrained PCB designs in consumer and industrial electronics applications.
Does the TLC5917IPW have any fault detection features?
Yes, the TLC5917IPW includes open-circuit detection functionality. It can detect when an LED or output load is missing or has failed open, and report this fault condition through the serial interface. This makes it suitable for applications requiring LED health monitoring, such as industrial indicators and automotive lighting systems.
What is a compatible alternative to the TLC5917IPW?
Compatible alternatives to the TLC5917IPW include the TLC5916IPW (similar 8-channel driver without open-circuit detection) and the TLC5919IPW (with additional PWM brightness control). From other manufacturers, the TPIC6595 and A6276 offer similar 8-channel serial-input LED driver functionality at comparable voltage and current ratings.
