Descrizione

Traduzione AI

TLC696x2/4/8 devices are a family of LCD local dimming back-light driver compatible with TLC696x0 which is a scan MOSFET controller to achieve 2/4/8 time-multiplexing control. Each device integrates 16 constant current sinks with corresponding size of SRAM for brightness storage. The device connects to each other by two-wire serial interface in diasy chain topology and supports up to 1024 devices for more than 32,000 local dimming zones. 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 achieve simplified system layout. The device also integrates minimum brightness update latency, black insertion and VRR features to improve display quality. TLC696x2/4/8 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.
