- DESCRIPTION
LED Matrix programmed via 1MHz I2C patible interface. Each LED can be dimmed individually with 8-bit PWM data, and each CSx has 8-bit DC scaling (Color Calibration) data which allowing 256 steps of linear PWM dimming for each dot and 256 steps of DC current adjustable level for each CSx.
Additionally, each LED open and short state can be detected, HTR3229 store the open or short information in Open-Short Registers. The Open-Short Registers allowing MCU to read out via I2C patible interface. Inform MCU whether there are LEDs open or short and the locations of open or short LEDs.
The HTR3229 operates from 2.5V to 5.5V and features a very low shutdown and operational current. HTR3229 is available in QFN-32 (4mm×4mm) package. It operates from 2.5V to 5.5V over the temperature range of -40°C to +125°C.
HTR3229 是 一 款 通 过 1MHz 的 I2C 接 口 进 行编程的支持16×8或15×9阵列的LED驱动 芯片，每路LED都支持8位PWM数据进行独立 调光，并且每路CSx都有8位的直流扫描数据用 来支持每个点的256阶的线性PWM调光，并且 每个CSx都支持256阶的直流电流可调节等级。
另外，每个LED的开路和短路状态都能被 检测，HTR3229能够把开路和短路信息存储在 Open-Short寄存器组中。这个寄存器组允许 MCU通过I2C接口读取用以告诉MCU这些LED 灯是否是在开路或者短路状态以及位置信息。...
