LC75760UJA数据手册集成电路（IC）的LED驱动器规格书PDF

描述 Description

The LC75760UJA is 12 Channel LED driver having shift register circuit (serial input, series / parallel output), latch circuit, LED driver of the constant current output type. It is usable for display such as illumination, the backlight LED, the warning light of the instrument panel. This LSI has 6ch PWM (Pulse Width Modulation) function to perform brightness adjustment of the LED. Furthermore, built-in the thermal protection function and open / short / adjacent outputs short detection function.

特性 Features

• The LED driver outputs of up to 12-ch can drive LED directly- Absolute maximum rating 6.8 V, maximum operating voltage 6.3 V- Absolute maximum rating 60 mA, maximum operating current 50 mA- Output current regulation function (256 Steps)- Open / short / adjacent outputs short detection function- Slew rate limited switching function
• Serial data communication supports 4-line serial format- Support 3.3 V and 5.0 V operation- Maximum operating frequency 2 MHz
• Built-in 6ch PWM function for brightness adjustment of LED- Resolution of 128, 256, 512 or 1024 steps- PWM frame frequency can be controlled by serial data
• Built-in thermal protection function(125 °C : automatic adjustment of PWM, 150 ºC : forced-off all LEDs)
• Provides the ERR output pin(125 °C temperature abnormality, open / short / adjacent outputs short abnormality, LED pull-up supply voltage abnormality, external resistance abnormally, fundamental clock abnormality, reset action)
• Provides a RES pin and built-in voltage detection type reset circuit (VDET) for LSI internal initialization
• Switch of the internal oscillator operating mode and the external clock operating mode can be controlled by serial data

简介

LC75760UJA属于集成电路（IC）的LED驱动器。由制造生产的LC75760UJALED 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。
