Procurement Notes
Verify the specific suffix BQFT against official datasheets to confirm tape and reel packaging and lead-free status. Confirm end-of-life status as distribution channels may vary. Ensure compatibility with existing PCB footprints and thermal requirements before finalizing procurement orders.
Selection Notes
Select this component when 16 individually addressable channels with per-LED calibration are required. It is suitable for applications needing high contrast ratios and low power consumption in compact form factors. Compare pinout and electrical specifications against alternative drivers if space constraints or interface protocols differ from standard SPI configurations.
Part Context
This part belongs to the AS1112 family of LED drivers designed for mobile and portable electronics. It shares functional similarities with other series members but differs in packaging and specific electrical characteristics. The family is widely used in smartphone and tablet display backlights where size and efficiency are critical design parameters.
Replacement Considerations
Check for direct substitutes such as AS1112 variants with different suffixes. Verify pin-to-pin compatibility and electrical equivalence before substitution. Consult manufacturer notices for recommended replacements if the part is discontinued.
FAQ
What type of dimming does the AS1112C-BQFT support?
It supports both analog and pulse-width modulation (PWM) dimming methods.
How many output channels are available on this IC?
The device provides 16 independent constant current sink channels.
