LV5234V中文资料LED Driver, 9-Channel数据手册ONSEMI规格书

描述 Description

The LV5234V is a 9-channel LED driver IC that is capable of switching between constant-current output and open drain output. It enables 3-wire serial bus control (address designation)/I2C serial bus control to be set arbitrarily using an external pin. Also possible are 9-channel LED ON/OFF control and the setting of the PWM luminance in 256 steps. The device also has a built-in fade-in/fade-out function. Up to 32 driver ICs can be connected using the slave address
setting pins.

特性 Features

• 9-channel output constant-current LED driver/open drain output LED driver (selected by using an external pin)
• Luminance adjustment using internal PWM control (256 steps)
• Fade-in/fade-out function (PWM control priority), supporting synchronous connection
• Selection of 3-wire/I2C serial bus control signals enabled (switching using an external pin)
• Low current consumption
• Output malfunction protection circuits (thermal protection function, UVLO detection protection function)

简介

LV5234V属于集成电路（IC）的LED驱动器。由制造生产的LV5234VLED 驱动器器件属于 LED 驱动器电源管理集成电路 (PMIC) 系列，可通过标称固定电压的电源为负载（通常为发光二极管）提供电流，并且电流可控。它与用于电压调节的类似产品的主要区别在于，这类器件提供较低的反馈电压（以提高系统能效），而且通常可对器件工作点进行外部控制，可在照明应用中用于实现调光功能。
