Texas Instruments TLC696x0/TLC696x0-Q1 8-Scan MOSFET Controllers are 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 a ghost-cancellation function to eliminate upside ghosting.
The device uses an adaptive headroom voltage control scheme to control DC/DC directly to optimize system efficiency. Only the FB pin from the last device in the serial chain should be connected to DC/DC to achieve a simplified system layout. The device also integrates minimum brightness update latency, black insertion, and VRR features to improve display quality.
The Texas Instruments TLC696x0/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 the register. The LTLC696x0-Q1 devices are AEC-Q100 qualified for automotive applications.
