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.
