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.
