Automotive 12-channel 75 mA constant-current LED driver with SPI diagnostics and dot correction, HTSSOP-28 PowerPAD
The Texas Instruments TLC6C5712QPWPRQ1 is an AEC-Q100 Grade 1, 12-channel constant-current LED sink driver for automotive instrument clusters and other lighting where uniform brightness matters. Each channel sinks up to 75 mA set by one external resistor, with 8-bit dot correction, six PWM inputs and a 16-bit SPI interface with full diagnostics (open, short, adjacent-pin short, thermal prewarning). Lead times on automotive TI LED drivers remain extended; Cerametronics helps buyers locate traceable stock.

Quality & Traceability
Cerametronics is ISO 9001 certified and products are RoHS compliant, with counterfeit screening and full traceability on every shipment. A Certificate of Conformance is available on request. For allocation-sensitive or high-risk lots, independent third-party lab verification can be arranged — just flag it on your RFQ. Any lot that fails incoming inspection is quarantined and never shipped.
FAQ
Is there a version with more channels?
Yes. TI lists the TLC6C5716-Q1 as the 16-channel member of the same family. Check its package and pinout against your layout before switching; plan for a board change.
How is the channel current set?
A single external reference resistor sets the full-scale current for all channels; the 8-bit dot correction then trims each channel through SPI.
