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.
