LED8102S集成電路（IC）的LED驅(qū)動器規(guī)格書PDF中文資料

LED8102S屬于集成電路（IC）的LED驅(qū)動器。由意法半導(dǎo)體集團制造生產(chǎn)的LED8102SLED 驅(qū)動器器件屬于 LED 驅(qū)動器電源管理集成電路 (PMIC) 系列，可通過標(biāo)稱固定電壓的電源為負載（通常為發(fā)光二極管）提供電流，并且電流可控。它與用于電壓調(diào)節(jié)的類似產(chǎn)品的主要區(qū)別在于，這類器件提供較低的反饋電壓（以提高系統(tǒng)能效），而且通常可對器件工作點進行外部控制，可在照明應(yīng)用中用于實現(xiàn)調(diào)光功能。

Description

The LED8102S is a monolithic, low voltage, 8 low-side-channel LED driver. The

LED8102S guarantees up to 19 V output driving capability allowing users to connect

several LEDs in series. In the output stage, 8 regulated current sources provide from

5 mA to 100 mA constant current to drive the LEDs. Current is programmed through

a single external resistor.

LED8102S is equipped with a thermal management that protects the device forcing

it in shutdown (typically: power-off at 170 °C with 15 °C hysteresis to restart). The

thermal protection switches OFF only the output channels.

The operative supply voltage range is between 3 V and 5.5 V. The output control

is provided by four switch inputs, providing an on/off toggle action suitable also for

local dimming. Moreover, on all active output LEDs brightness can be adjusted with a

global PWM signal applied to the output enable pin (OE). Outputs can be connected

in parallel, or left unconnected if not used, as required by the application.

Applications
