3 Description

TLC696x0-Q1 is a scan MOSFET controller

compatible with current-sink driver TLC696x2/4/8-Q1

to achieve 2/4/8 time-multiplexing control. Each

device integrates with 16 constant current sinks for

up to 8 scan MOSFETs control. The device equips

with ghost-cancellation function to eliminate upside

ghosting.

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.

TLC696x0-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/CLK_O which is programmable

by register.
