3 Description

TLC696x0 is a scan MOSFET controller compatible

with current-sink driver TLC696x2/4/8 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 equips 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 acheive

simplified system layout. The device also integrates

minimum brightness update latency, black insertion

and VRR features to improve display quality.

TLC696x0 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.
