AL58263数据手册Diodes中文资料规格书

描述 Description

The AL58263 is a 16-channel constant-current LED driver with 16-bit grayscale Adaptive Pulse Density Modulation (APDM) and supports error diagnostics, power-saving functionality, and current gain control. This distinctive APDM technology abates the non-ideal IOUT distortion due to non-symmetric transient responses and enhances the refresh rate by efficiently separating the frame waveform.


The device operates over a 3V to 5.5V input voltage range, 15V output channel voltage, fast 25MHz DCK input, and delivers up to 55mA of high-accuracy current to each LED string. Each channel’s output current is programmable by an external current-sensing resistor and can be adjusted by 6-bit global current control.


The AL58263 has built-in diagnostics and LED open/short protection, including error detection. These error results are stored in a register for the MCU to read out.


The AL58263 is available in the TSSOP-24EP (Type A1-B) package and specified over the -40°C to +85°C ambient temperature range.
