Automotive mini-LED local dimming backlight driver with 60-mA 16-channel integrated current sink | PWP | 28 | -40 to 125

TLC696x1-Q1 is a 16-channel, constant current sink driver. Each device integrates 16

constant current sinks with SRAM for brightness storage. The device connects to each other

by two-wire serial interface in daisy chain topology and supports up to 1024 devices for

16,000 local dimming zones.

To optimize system efficiency, the device is

equipped with adaptive headroom voltage control scheme to directly control DC/DC. Only the

FB pin from last device in serial chain should be connected to DC/DC to achieve simplified

system layout. The device also integrates minimum brightness update latency, black insertion

and VRR features to improve display quality.

TLC696x1-Q1 has three error flags: LED open detection (LOD), LED short detection (LSD)

and thermal shutdown detection (TSD) for diagnostic. The device implements two options for

readback including UART/INT and SOUT/CLKO which is programmable by register.
