SCT2024 16-bit Serial-In/Parallel-Out Constant-Current LED Driver
Features
* 16 robust constant current sinker with LED powersupply voltage up to 17V
* Constant output current : 5 – 30/45mA@3.3/5V
* Wide power supply voltages: 3.3V to 5V
* Excellent regulation to load, supply voltage and temperature
Temperature regulation: ±0.005%/°C,
Load regulation: ±0.1%/V
Line regulation: ±0.5%/V
* High current matching accuracy: ±1% between outputs, ±2% between ICs
* Fine grayscale response with 180ns PWM pulse width
* Dropout voltage 0.5V@20mA, VDD=5V
* CMOS Schmitt trigger inputs with clock rate up to 25MHz @ cascade connection
* The constant current value of 16 outputs is set by a single external resistor
* Interlaced 30ns delay of output, preventing instant current surge and output bouncing overstress
* Builtin power on reset(POR) circuit forces all the outputs off while power on
* Package: SSOP24, SSOP241, SOP24 and TQFN24
