DESCRIPTION
The LD1072 is a 16-channel, constant-current sink, LED driver. Each channel has a individually adjustable12- Bit PWM brightness control and a 64-step/256-step dot correction. The dot correction adjusts the brightness variations between LED channels and other LED Drivers. In 8-Bit Mode, LD1072 has 256-step Programmable Adjust Data Mode which controls 16 output current simultaneously. Both PWM control and dot correction are accessible via a serial interface. An external resistor sets the maximum current value of all 16 channels.
The LD1072 features two error information circuits. The LED open detection (LOD) indicates a broken or disconnected LED at an output terminal. The thermal error flag (TEF) indicates an over temperature status.
