LV52511MN中文资料Linear LED Driver, 24-channel, BUS controlled数据手册ONSEMI规格书

描述 Description

The LV52511MN is a serial bus controlled linear low side driver for LEDs (or other loads). The 24 channels are grouped in 3 color blocks (RGB) of 8bit channels each. The ON-time for each channel can be programmed by 8bit resister. The reference current is decided by a single resister (3 to 100%) of the reference current to adjust for color temperature.
Systems parameters can be programmed via 2 wire serial bus, or 3 wire SPI bus with EN, and I2C serial bus format.

特性 Features

• System Supply from 3V to 20V with Transient Tolerance up to 24V
• Up to 60mA Resistor Defined Maximum Current for All Channels
• 5bit Individually Adjustable Current for each Color Group RGB
• 8bit Luminance Dimming for each Channel
• 2 or 3 Wire Bus Interface with up to 56 Slave Address
• TSD and UVLO protection
• Thermally Efficient Exposed Die 48 pin QFN Package for Operation up to 85deg Ambient

应用 Application

• LED Displays
• LED Drivers
• Gamming (Slot Machine) and Entertainment Equipment
• Digital Information Signs
• Indicator of various machine

简介

LV52511MN属于集成电路（IC）的LED驱动器。由制造生产的LV52511MNLED 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。
